Title: Color converting substrate and display device including same

Description:
This application claims priority to Korean Patent Application 10-2019-0060380 filed on May 23, 2019, and Korean Patent Application 10-2020-0047482 filed on Apr. 20, 2020, all the benefits accruing therefrom under 35 U.S.C. 119, the contents of which in their entirety are herein incorporated by reference. 
     TECHNICAL FIELD 
     The disclosure relates to a color converting substrate and a display device including the same. 
     BACKGROUND ART 
     A display device is becoming more important with developments in multimedia technology. Accordingly, various display devices such as a liquid crystal display (“LCD”) device, an organic light-emitting diode (“OLED”) display device, and the like have been used. 
     A self-luminous display device, which is a type of the display device, includes self-luminous elements such as OLEDs. Each of the self-luminous elements may include two electrodes facing each other and an emission layer interposed between the two electrodes. In a case where the self-luminous elements are OLEDs, electrons and holes from the two electrodes may recombine together in the emission layer to generate excitons, and light may be emitted in response to the transition of the excitons from an excited state to a ground state. 
     The self-luminous display device does not need a separate light source and can thus be implemented as a low-power consumption, thin, light-weight display device with high-quality characteristics such as wide viewing angles, high luminance and contrast, and a fast response speed, drawing attention as a next-generation display device.

     MODES OF THE INVENTION 
     The invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. 
     It will also be understood that when a layer is referred to as being “on” another layer or substrate, it can be directly on the other layer or substrate, or intervening layers may also be. The same reference numbers indicate the same components throughout the specification. 
     Spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper” and the like, may be used herein for ease of description to describe one element or feature&#39;s relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. 
     It will be understood that, although the terms “first,” “second,” “third,” “fourth,” etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For instance, a first element discussed below could be termed one of a second element, a third element, and a fourth element without departing from the teachings of the invention. 
     The invention will be described with reference to perspective views, cross-sectional views, and/or plan views, in which preferred embodiments of the invention are shown. Thus, the profile of a view may be modified according to manufacturing techniques and/or allowances. That is, the embodiments of the invention are not intended to limit the scope of the invention but cover all changes and modifications that can be caused due to a change in manufacturing process. Thus, regions shown in the drawings are illustrated in schematic form and the shapes of the regions are presented simply by way of illustration and not as a limitation. 
     Hereinafter, embodiments will be described with reference to the accompanying drawings. 
       FIG. 1  is a perspective view of a display device according to an embodiment of the disclosure.  FIG. 2  is a cross-sectional view taken along line Xa-Xa′ of  FIG. 1 . 
     Referring to  FIGS. 1 and 2 , a display device  1  may be applicable to various electronic devices, for example, a mid- to small-size electronic device such as a tablet personal computer (“PC”), a smartphone, a vehicular navigation unit, a camera, the center information display (“CID”) of a vehicle, a wristwatch-type electronic device, a personal digital assistant (“PDA”), a portable multimedia player (“PMP”), or a gaming console and a mid- to large-size electronic device such as a television (“TV”), an electronic billboard, a monitor, a PC, or a notebook computer, but the disclosure is not limited thereto.

The display substrate  10  and the color converting substrate  30  may be coupled to each other by the sealing portion  50 . In some embodiments, the sealing portion  50  may be formed of an organic material. In one example, the sealing portion  50  may be formed of an epoxy resin, but the disclosure is not limited thereto.

In some embodiments, the filler  70  may not be provided. 
       FIG. 3  is a plan view of the display substrate in the display area of the display device of  FIGS. 1 and 2 .  FIG. 4  is a plan view of a color converting substrate in the display area of the display device of  FIGS. 1 and 2 . 
     Referring to  FIGS. 1 through 4 , a plurality of emission regions LA (LA 1 , LA 2 , LA 3 , LA 4 , LA 5 , and LA 6 ) and the non-emission region NLA may be defined in the display area DA of the display substrate  10 . The emission regions LA (LA 1 , LA 2 , LA 3 , LA 4 , LA 5 , and LA 6 ) may be regions through which light generated by light-emitting elements is released to the outside from the display substrate  10 , and the non-emission region NLA may be a region through which light is not released to the outside from the display substrate  10 . 
     In one example, light released by the emission regions (LA 1 , LA 2 , LA 3 , LA 4 , LA 5 , and LA 6 ) to the outside of the display substrate  10  may be light of a first color. In some embodiments, light of the first color may be blue light and may have a peak wavelength of about 440 nanometers (nm) to about 480 nm. 
     The display area DA of the display substrate  10  may include emission regions (LA 1 , LA 2 , and LA 3 ) that are arranged in a first row RL 1  and emission regions (LA 4 , LA 5 , and LA 6 ) that are arranged in a second row RL 2 . First emission regions LA 1 , second emission regions LA 2 , and third emission regions LA 3  may be arranged in the first row RL 1  along the first direction DR 1 . In one example, the display substrate  10  may include a first region where the first emission regions LA 1 , the second emission regions LA 2 , and the third emission regions LA 3  are arranged in the order of first, second, and third emission regions LA 1 , LA 2 , and LA 3  along the first direction DR 1  and a second region where the first emission regions LA 1 , the second emission regions LA 2 , and the third emission regions LA 3  are arranged in the order of third, second, and first emission regions LA 3 , LA 2 , and LA 1  along the first direction DR 1 . 
     In the first row RL 1  of the display substrate  10 , the first emission regions LA 1 , the second emission regions LA 2 , and the third emission regions LA 3  may be arranged in the order of first, second, and third emission regions LA 1 , LA 2 , and LA 3  along the first direction DR 1  and then in the order of third, second, and first emission regions LA 3 , LA 2 , and LA 1  along the first direction DR 1 . Accordingly, a third emission region LA 3  may be disposed adjacent to another third emission region LA 3  in the first direction DR 1 , but the disclosure is not limited thereto. Although not specifically illustrated, a first emission region LA 1  may also be disposed adjacent to another first emission region LA 1  in the first direction DR 1 , but the disclosure is not limited thereto. In some embodiments, even a second emission region LA 2  may also be disposed adjacent to another second emission region LA 2  in the first direction DR 1 . 
     The display substrate  10  may include regions where identical emission regions LA (this is a representative name of the emission regions LA 1  to LA 6 ) are disposed adjacent to one another. In the second row RL 2 , which is adjacent to the first row RL 1  in the second direction DR 2 , the fourth emission regions LA 4 , the fifth emission regions LA 5 , and the sixth emission regions LA 6  may be arranged in the order of fourth, fifth, and sixth emission regions LA 4 , LA 5 , and LA 6  along the first direction DR 1  and then in the order of sixth, fifth, and fourth emission regions LA 6 , LA 5 , and LA 4  along the first direction DR 1 . In the regions where identical emission regions LA are disposed adjacent to one another, identical light transmitting regions TA (this is a representative name of the emission regions TA 1  to TA 6 ) of the color converting substrate  30  that will be described later may also be disposed adjacent to one another. This will be described later in detail. 
     In some embodiments, a first width WL 1 , in the first direction DR 1 , of first emission regions LA 1  may be greater than each of a second width WL 2 , in the first direction DR 1 , of second emission regions LA 2  and a third width WL 3 , in the first direction DR 1 , of third emission regions LA 3 . Also, the second width WL 2  of the second emission regions LA 2  may differ from the third width WL 3  of the third emission regions LA 3 . In one example, the second width WL 2  of the second emission regions LA 2  may be greater than the third width WL 3  of the third emission regions LA 3  in the first direction DR 1 . In some embodiments, the size of the first emission regions LA 1  may be greater than each of the size of the second emission regions LA 2  and the size of the third emission regions LA 3 . The size of the second emission regions LA 2  may be greater than the size of the third emission regions LA 3 . 
     However, the disclosure is not limited to this. The first width WL 1  of the first emission regions LA 1 , the second width WL 2  of the second emission regions LA 2 , and the third width WL 3  of the third emission regions LA 3  may all be substantially the same in another embodiment. Also, in some embodiments, the size of the second emission regions LA 2  may be smaller than the size of the third emission regions LA 3 . Also, the size of the first emission regions LA 1 , the size of the second emission regions LA 2 , and the size of the third emission regions LA 3  may all be substantially the same in another embodiment. The width of emission regions LA is illustrated as gradually decreasing from the first emission regions LA 1  to the third emission regions LA 3 , but the disclosure is not limited thereto. 
     Fourth emission regions LA 4 , which are adjacent to their respective first emission regions LA 1  in the second direction DR 2 , may be the same as the first emission regions LA 1  except that they are arranged in the second row RL 2 , and the width, size, and arrangement of the fourth emission regions LA 4  may be substantially the same as the width, size, and arrangement of the first emission regions LA 1 . Similarly, fifth emission regions LA 5 , which are adjacent to their respective second emission regions LA 2  in the second direction DR 2 , may substantially the same structure as the second emission regions LA 2 , and sixth emission regions LA 6 , which are adjacent to their respective third emission regions LA 3  in the second direction DR 2 , may substantially the same structure as the third emission regions LA 3 . 
     The color converting substrate  30  may face the display substrate  10  in a plan view. A plurality of light transmitting regions TA (TA 1 , TA 2 , TA 3 , TA 4 , TA 5 , and TA 6 ) and light blocking regions BA may be defined in the display area DA of the color converting substrate  30 . The light transmitting regions TA (TA 1 , TA 2 , TA 3 , TA 4 , TA 5 , and TA 6 ) may be regions through which light emitted from the display substrate  10  is provided to the outside of the display substrate  10  through the color converting substrate  30 . The light blocking regions BA may be regions that do not transmit light emitted from the display substrate  10  therethrough. 
     The color converting substrate  30  may include light transmitting regions (TA 1 , TA 2 , and TA 3 ) that are arranged in a first row RT 1  and light transmitting regions (TA 4 , TA 5 , and TA 6 ) that are arranged in a second row RT 2 . First light transmitting regions TA 1 , second light transmitting regions TA 2 , and third light transmitting regions TA 3  may be arranged in the first row RT 1  along the first direction DR 1 . In one example, the color converting substrate  30  may include a first region where the first light transmitting regions TA 1 , the second light transmitting regions TA 2 , and the third light transmitting regions TA 3  are arranged in the order of first, second, and third light transmitting regions TA 1 , TA 2 , and TA 3  along the first direction DR 1  and a second region where the first light transmitting regions TA 1 , the second light transmitting regions TA 2 , and the third light transmitting regions TA 3  are arranged in the order of third, second, and first light transmitting regions TA 3 , TA 2 , and TA 1  along the first direction DR 1 . 
     First light transmitting regions TA 1  may correspond to or overlap with the first emission regions LA 1  in the plan view.

As described above, the first emission regions LA 1 , the second emission regions LA 2 , and the third emission regions LA 3  may be arranged in the order of first, second, and third emission regions LA 1 , LA 2 , and LA 3  or third, second, and first emission regions LA 3 , LA 2 , and LA 1  in the first direction DR 1 , and the first light transmitting regions TA 1 , the second light transmitting regions TA 2 , and the third light transmitting regions TA 3 , which correspond to or overlap with the first emission regions LA 1 , the second emission regions LA 2 , and the third emission regions LA 3  in the plan view, respectively, may be arranged in the order of first, second, and third light transmitting regions TA 1 , TA 2 , and TA 3  or third, second, and first light transmitting regions TA 3 , TA 2 , and TA 1  in the first direction DR 1 . The third light transmitting regions TA 3  are illustrated as being disposed adjacent to each other, but the disclosure is not limited thereto. The first light transmitting region TA 1  may also be disposed adjacent to other first light transmitting regions TA 1 , but the disclosure is not limited thereto. Alternatively, the second light transmitting regions TA 2  may be disposed adjacent to other second light transmitting regions TA 2 . 
     First-color light provided by the display substrate  10  may be provided to the outside of the display device  1  through the first light transmitting regions TA 1 , the second light transmitting regions TA 2 , and the third light transmitting regions TA 3 . When light emitted from the first light transmitting regions TA 1  to the outside of the display device  1  is referred to as first outgoing light, light emitted from the second light transmitting regions TA 2  to the outside of the display device  1  is referred to as second outgoing light, and light emitted from the third light transmitting regions TA 3  to the outside of the display device  1  is referred to as third outgoing light, the third outgoing light may be light of the first color, the second outgoing light may be light of a second color, which is different from the first color. The first outgoing light may be light of a third color, which is different from the first and second colors. In some embodiments, light of the first color may be blue light having a peak wavelength of about 440 nm to about 480 nm, light of the second color may be green light having a peak wavelength of about 510 nm to about 550 nm, and light of the third color may be red light having a peak wavelength of about 610 nm to about 650 nm. 
     In the second row RT 2 , which is adjacent to the first row RT 1  in the second direction DR 2 , fourth light transmitting regions TA 4 , fifth light transmitting regions TA 5 , and sixth light transmitting regions TA 6  may be arranged. The fourth light transmitting regions TA 4 , the fifth light transmitting regions TA 5 , and the sixth light transmitting regions TA 6  may be arranged in the order of fourth, fifth, and sixth light transmitting regions TA 4 , TA 5 , and TA 6  or sixth, fifth, and fourth light transmitting regions TA 6 , TA 5 , and TA 4  in the first direction DR 1 . The fourth emission regions TA 4  may correspond to or overlap with the fourth emission regions LA 4 , the fifth light transmitting regions TA 5  may correspond to or overlap with the fifth emission regions LA 5 , and the sixth light transmitting regions TA 6  may correspond to or overlap with the sixth emission regions LA 6  in the plan view. 
     In some embodiments, a width WT this is a representative name of the widths WT 1  to WT 3 ), in the first direction DR 1 , of the first light transmitting regions TA 1 , the second light transmitting regions TA 2 , and the third light transmitting regions TA 3  may be similar to the width of the first emission regions LA 1 , the second emission regions LA 2 , and the third emission regions LA 3 . In one example, a first width WT 1 , in the first direction DR 1 , of the first light transmitting regions TA 1  may be greater than each of a second width WT 2 , in the first direction DR 1 , of the second light transmitting regions TA 2  and a third width WT 3 , in the first direction DR 1 , of the third light transmitting regions TA 3 . Also, the second width WT 2  of the second light transmitting regions TA 2  may differ from the third width WT 3  of the third light transmitting regions TA 3 . In one example, the second width WT 2  of the second light transmitting regions TA 2  may be greater than the third width WT 3  of the third light transmitting regions TA 3 . 
     Also, in some embodiments, size of the first light transmitting regions TA 1  may be greater than each of the sizes of the second light transmitting regions TA 2  and the third light transmitting regions TA 3 , and the size of the second light transmitting regions TA 2  may be greater than the size of the third light transmitting regions TA 3 . The configurations of the fourth light transmitting regions TA 4 , the fifth light transmitting regions TA 5 , and the sixth light transmitting regions TA 6  may be substantially the same as the configurations of the first light transmitting regions TA 1 , the second light transmitting regions TA 2 , and the third light transmitting regions TA 3 , which are adjacent to the fourth light transmitting regions TA 4 , the fifth light transmitting regions TA 5 , and the sixth light transmitting regions TA 6 , respectively, in the second direction DR 2 . The colors of light emitted to the outside of the display device  1  through the fourth light transmitting regions TA 4 , the fifth light transmitting regions TA 5 , and the sixth light transmitting regions TA 6  may be substantially the same as the colors of light emitted to the outside of the display device  1  through the first light transmitting regions TA 1 , the second light transmitting regions TA 2 , and the third light transmitting regions TA 3 , respectively. 
     The light blocking regions BA may be positioned around the light transmitting regions (TA 1 , TA 2 , TA 3 , TA 4 , TA 5 , and TA 6 ), in the display area DA of the color converting substrate  30 . In some embodiments, the light blocking regions BA may include first light blocking regions BA 1 , second light blocking regions BA 2 , a third light blocking region BA 3 , fourth light blocking regions BA 4 , fifth light blocking regions BA 5 , a sixth light blocking region BA 6 , seventh light blocking regions BA 7 , eighth light blocking regions BAB, and ninth light blocking regions BA 9 .

The seventh light blocking regions BA 7  may be positioned between the first light transmitting regions TA 1  and other first light transmitting regions TA 1  (not illustrated). That is, the first light blocking regions BA 1  and the second light blocking regions BA 2  may each be positioned between two different adjacent light transmitting regions, for example, between first and second light transmitting regions TA 1  and TA 2  or between second and third light transmitting regions TA 2  and TA 3 . Each of the third light blocking region BA 3  and the seventh light blocking regions BA 7  may be positioned between two identical adjacent light transmitting regions, for example, between two first light transmitting regions TA 1  or between two third light transmitting regions TA 3 .

That is, the fourth light blocking regions BA 4  and the fifth light blocking regions BA 5  may each be positioned between two different adjacent light transmitting regions, for example, between fourth and fifth light transmitting regions TA 4  and TA 5  or between fifth and sixth light transmitting regions TA 5  and TA 6 . Each of the sixth light blocking region BA 6  and the eighth light blocking regions BA 8  may be positioned between two identical adjacent light transmitting regions, for example, between two sixth light transmitting regions TA 6  or between two fourth light transmitting regions TA 4 . 
     The ninth light blocking regions BA 9  may be positioned between the first and second rows RT 1  and RT 2 , which are adjacent to each other in the second direction DR 2 . 
     The structure of the display device  1  will hereinafter be described in detail. 
       FIG. 5  is a cross-sectional view taken along line X 1 -X 1 ′ of  FIGS. 3 and 4 .  FIG. 6  is a cross-sectional view taken along line X 2 -X 2 ′ of  FIGS. 3 and 4 .  FIG. 7  is an enlarged cross-sectional view of part Q of  FIG. 5 .  FIGS. 8 and 9  are cross-sectional views of modified examples of the part Q of  FIG. 7 . 
       FIG. 5  is a cross-sectional view taken across first, second, and third emission regions LA 1 , LA 2 , and LA 3  of the display substrate  10  and across first, second, and third light transmitting regions TA 1 , TA 2 , and TA 3  of the color converting substrate  30 .  FIG. 6  is a cross-sectional view taken across a second emission region LA 2 , a third emission region LA 3 , and another third emission region LA 3  of the display substrate  10  and across a second light transmitting region TA 2 , a third light transmitting region TA 3 , and another third light transmitting region TA 3  of the color converting substrate  30 . 
     Referring to  FIGS. 5 through 9  and further to  FIGS. 3 and 4 , the display device  1  may include the display substrate  10  and the color converting substrate  30 , as described above, and may further include the filler  70 , which is positioned between the display substrate  10  and the color converting substrate  30 . The display substrate  10  will hereinafter be described in detail. 
     The display substrate  10  may include a first base part  110  and a plurality of switching elements (T 1 , T 2 , and T 3 ), which are disposed on the first base part  110 . 
     The first base part  110  may be formed of a material a light transmitting property. In some embodiments, the first base part  110  may be a glass substrate or a plastic substrate. In a case where the first base part  110  is a plastic substrate, the first base part  110  may have flexibility. In some embodiments, the first base part  110  may include a separate layer (e.g., a buffer layer or an insulating layer) positioned on a glass substrate or a plastic substrate. In some embodiments, the emission regions (LA 1 , LA 2 , LA 3 , LA 4 , LA 5 , and LA 6 ) and the non-emission region NLA may be defined on the first base part  110 . 
     The switching elements (T 1 , T 2 , and T 3 ) may be disposed on the first base part  110 . In some embodiments, first switching elements T 1  may be positioned in the first emission regions LA 1 , second switching elements T 2  may be positioned in the second emission regions LA 2 , and third switching elements T 3  may be positioned in the third emission regions LA 3 . However, the disclosure is not limited to this. In other embodiments, the first switching elements T 1 , the second switching elements T 2 , and/or the third switching elements T 3  may be positioned in the non-emission region NLA. 
     In some embodiments, the first switching elements T 1 , the second switching elements T 2 , and the third switching elements T 3  may be thin-film transistors including polysilicon or an oxide semiconductor. 
     Although not specifically illustrated, a plurality of signal lines (e.g., gate lines, data lines, and power lines) for transmitting signals to each switching element may be further disposed on the first base part  110 . 
     An insulating film  130  may be disposed on the first switching elements T 1 , the second switching elements T 2 , and the third switching elements T 3 . In some embodiments, the insulating film  130  may be a planarization film. In some embodiments, the insulating film  130  may be formed as an organic film. In one example, the insulating film  130  may include an acrylic resin, an epoxy resin, an imide resin, or an ester resin. In some embodiments, the insulating film  130  may include a positive photosensitive material or a negative photosensitive material. 
     First anode electrodes AE 1 , second anode electrodes AE 2 , and third anode electrodes AE 3  may be disposed on the insulating film  130 . The first anode electrodes AE 1  may be positioned in the first emission regions LA 1  and may extend at least in part into the non-emission region NLA. The second anode electrodes AE 2  may be positioned in the second emission regions LA 2  and may extend at least in part into the non-emission region NLA, and the third anode electrodes AE 3  may be positioned in the third emission regions LA 3  and may extend at least in part into the non-emission region NLA. The first anode electrodes AE 1  may be connected to the first switching elements T 1  through the insulating film  130 , the second anode electrodes AE 2  may be connected to the second switching elements T 2  through the insulating film  130 , and the third anode electrodes AE 3  may be connected to the third switching elements T 3  through the insulating film  130 . 
     In some embodiments, the first anode electrodes AE 1 , the second anode electrodes AE 2 , and the third anode electrodes AE 3  may have different widths or areas from each other. In one example, the width of the first anode electrodes AE 1  may be greater than the width of the second anode electrodes AE 2 , and the width of the second anode electrodes AE 2  may be smaller than the width of the first anode electrodes AE 1 , but greater than the width of the third anode electrodes AE 3 . The area of the first anode electrodes AE 1  may be greater than the area of the second anode electrodes AE 2 , and the area of the second anode electrodes AE 2  may be smaller than the area of the first anode electrodes AE 1 , but greater than the area of the third anode electrodes AE 3 . However, the disclosure is not limited to this. Alternatively, the area of the first anode electrodes AE 1  may be smaller than the area of the second anode electrodes AE 2 , and the area of the third anode electrodes AE 3  may be greater than the area of the second anode electrodes AE 2  and the area of the first anode electrodes AE 1 . Alternatively, the first anode electrodes AE 1 , the second anode electrodes AE 2 , and the third anode electrodes AE 3  may have substantially the same width or area. 
     The first anode electrodes AE 1 , the second anode electrodes AE 2 , and the third anode electrodes AE 3  may be reflective electrodes, in which case, the first anode electrodes AE 1 , the second anode electrodes AE 2 , and the third anode electrodes AE 3  may be metal layers including a metal such as Ag, Mg, Al, Pt, Pd, Au, Ni, Nd, Ir, or Cr. In some embodiments, the first anode electrodes AE 1 , the second anode electrodes AE 2 , and the third anode electrodes AE 3  may further include metal oxide layers deposited on the metal layers. In one example, the first anode electrodes AE 1 , the second anode electrodes AE 2 , and the third anode electrodes AE 3  may have a double-layer structure such as ITO/Ag, Ag/ITO, ITO/Mg, or ITO/MgF or a multilayer structure such as ITO/Ag/ITO. 
     A pixel defining film  150  may be disposed on the first anode electrodes AE 1 , the second anode electrodes AE 2 , and the third anode electrodes AE 3 . The pixel defining film  150  may include openings that expose the first anode electrodes AE 1 , openings that expose the second anode electrodes AE 2 , and openings that expose the third anode electrodes AE 3  and may define the first emission regions LA 1 , the second emission regions LA 2 , the third emission regions LA 3 , and the non-emission region NLA. That is, parts of the first node electrodes AE 1  not covered, but exposed by the pixel defining film  150  may be the first emission regions LA 1 . Similarly, parts of the second node electrodes AE 2  not covered, but exposed by the pixel defining film  150  may be the second emission regions LA 2 , and parts of the third node electrodes AE 3  not covered, but exposed by the pixel defining film  150  may be the third emission regions LA 3 . The pixel defining film  150  may be positioned in the non-emission region NLA. 
     In some embodiments, the pixel defining film  150  may include an organic insulating material such as an acrylic resin, an epoxy resin, a phenolic resin, a polyamide resin, a polyimide resin, an unsaturated polyester resin, a polyphenylene resin, a polyphenylene sulfide resin, or benzocyclobutene (“BCB”). 
     In some embodiments, parts of the pixel defining film  150  may overlap with light blocking members  220 , barriers  370 , and a light blocking pattern  240  in the plan view. Here, the light blocking member  220  is a representative name of a first to nine light blocking member  221  to  229 . In one example, as illustrated in  FIG. 5 , the pixel defining film  150  may overlap with first light blocking members  221 , second light blocking members  222 , seventh light blocking members  227 , and the barriers  370  in the plan view. Also, the pixel defining film  150  may overlap with the light blocking pattern  240 , which is positioned between the third light transmitting regions TA 3 . 
     An emission layer OL may be positioned on the first anode electrodes AE 1 , the second anode electrodes AE 2 , and the third anode electrodes AE 3 . In some embodiments, the emission layer OL may have the shape of a continuous film formed across the emission regions (LA 1 , LA 2 , LA 3 , LA 4 , LA 5 , and LA 6 ) and the non-emission region NLA. The emission layer OL will be described later in detail. 
     A cathode electrode CE may be disposed on the emission layer OL. In some embodiments, the cathode electrode CE may be semi-transmissive or transmissive. In a case where the cathode electrode CE is semi-transmissive, the cathode electrode CE may include Ag, Mg, Cu, Al, Pt, Pd, Au, Ni, Nd, Ir, Cr, Li, Ca, LiF/Ca, LiF/Al, Mo, Ti, or a compound or mixture thereof (e.g., the mixture of Ag and Mg). Also, in a case where the cathode electrode CE has a thickness of several tens to hundreds of angstroms, the cathode electrode CE may have semi-transmissivity. 
     In a case where the cathode electrode CE is transmissive, the cathode electrode CE may include a transparent conductive oxide (“TCO”). In one example, the cathode electrode CE may include tungsten oxide (WxOx), titanium oxide (TiO 2 ), indium tin oxide (“ITO”), indium zinc oxide (“IZO”), zinc oxide (ZnO), indium tin zinc oxide (“ITZO”), or magnesium oxide (MgO). 
     The first anode electrodes AE 1 , the emission layer OL, and the cathode electrode CE may form first light-emitting elements ED 1 , the second anode electrodes AE 2 , the emission layer OL, and the cathode electrode CE may form second light-emitting elements ED 2 , and the third anode electrodes AE 3 , the emission layer OL, and the cathode electrode CE may form third light-emitting elements ED 3 . The first light-emitting elements ED 1 , the second light-emitting elements ED 2 , and the third light-emitting elements ED 3  may emit outgoing light L, and the outgoing light L may be provided to the color converting substrate  30 . 
     The display substrate  10  of the display device  1  may include first-type light-emitting elements that are adjacent to light-emitting elements ED of different types therefrom and second-type light-emitting elements that are adjacent to light-emitting elements of their type. As illustrated in  FIGS. 5 and 6 , a second light-emitting element ED 2  is adjacent to light-emitting elements ED of different types therefrom, i.e., first and third light-emitting elements ED 1  and ED 3 , in the first direction DR 1  and may thus be a first-type light-emitting element. 
     On the contrary, a third light-emitting elements ED 3  is adjacent to a second light-emitting element ED 2  and another third light-emitting element ED 3 . That is, a third light-emitting element ED 3  may be disposed adjacent to another light-emitting element of its type, i.e., another third light-emitting element ED 3 , and may thus be a second-type light-emitting element. Although not specifically illustrated, a first light-emitting element ED 1  is adjacent to another first light-emitting element ED 1  and a second light-emitting element ED 2  in the first direction DR 1  and may thus be a second-type light-emitting element. 
     The arrangement of the light-emitting elements ED may be associated with the arrangement of the emission regions LA and the light transmitting regions TA. As described above, as the third emission regions LA 3  are disposed adjacent to each other and the third light transmitting regions TA 3  are disposed adjacent to each other, the third light-emitting elements ED 3  may also be disposed adjacent to each other. This type of arrangement of the light-emitting elements ED may be obtained by arranging two identical light transmitting regions such as third light transmitting regions TA 3  adjacent to each other in the color converting substrate  30  and arranging two identical light-emitting elements adjacent to each other to correspond to the two identical light transmitting regions. The barriers  370  and the light blocking members  220  may not be provided between the third light transmitting regions TA 3  of the color converting substrate  30 , and the light blocking pattern  240  may be disposed between the third light transmitting regions TA 3  of the color converting substrate  30 . This will be described later in detail. 
     The emission layer OL of the light-emitting elements ED may have a stack of multiple layers. As illustrated in  FIGS. 7 through 9 , the emission layer OL may include a first hole transport layer HTL 1 , which is positioned on the first anode electrodes AE 1 , a first light-emitting material layer EL 11 , which is positioned on the first hole transport layer HTL 1 , and a first electron transport layer ETL 1 , which is positioned on the first light-emitting material layer EL 11 . The emission layer OL may include only one light-emitting layer, for example, only the first light-emitting material layer EL 11  as a light-emitting layer, and the first light-emitting material layer EL 11  may be a blue light-emitting layer. However, the stack structure of the emission layer OL is not particularly limited to that illustrated in  FIG. 7  and may vary, as illustrated in  FIGS. 8 and 9 . 
     Referring to  FIG. 8 , the emission layer OL may further include a first charge generation layer CGL 11 , which is positioned on a first light-emitting material layer EL 11 , and a second light-emitting material layer EL 12 , which is positioned on the first charge generation layer CGL 11 , and a first charge transport layer ETL 1  may be positioned on the second light-emitting material layer EL 12 . 
     The first charge generation layer CGL 11  may inject charges into each light-emitting layer adjacent thereto. The first charge generation layer CGL 11  may control the charge balance between the first and second light-emitting material layers EL 11  and EL 12 . In some embodiments, the first charge generation layer CGL 11  may include an n-type charge generation layer and a p-type charge generation layer. The p-type charge generation layer may be disposed on the n-type charge generation layer. 
     The second light-emitting material layer EL 12 , like the first light-emitting material layer EL 11 , may emit blue light, but the disclosure is not limited thereto. The second light-emitting material layer EL 12  may emit blue light having the same peak wavelength as, or a different peak wavelength from, the first light-emitting material layer EL 11 . Alternatively, the first and second light-emitting material layers EL 11  and EL 12  may emit light of different colors. That is, the first light-emitting material layer EL 11  may emit blue light, and the second light-emitting material layer EL 12  may emit green light. 
     As the above-described emission layer OL includes two light-emitting layers, the emission efficiency and the life of the emission layer OL can be improved as compared to the example of  FIG. 7 . 
       FIG. 9  illustrates an example in which the emission layer OL includes three light-emitting material layers (EL 11 , EL 12 , and EL 13 ) and two charge generation layers (CGL 11  and CGL 12 ). Referring to  FIG. 9 , the emission layer OL may further include a first charge generation layer CGL 11 , which is positioned on a first light-emitting material layer EL 11 , a second light-emitting material layer EL 12 , which is positioned on the first charge generation layer CGL 11 , a second charge generation layer CGL 12 , which is positioned on the second light-emitting material layer EL 12 , and a third light-emitting material layer EL 13 , which is positioned on the second charge generation layer CGL 12 . A first charge transport layer ETL 1  may be positioned on the third light-emitting material layer EL 13 . 
     The third light-emitting material layer EL 13 , like the first and second light-emitting material layers EL 11  and EL 12 , may emit blue light. In one example, the first, second, and third light-emitting material layers EL 11 , EL 12 , and EL 13  may all emit blue light. The peak wavelengths of beams of blue light emitted by the first, second, and third light-emitting material layers EL 11 , EL 12 , and EL 13  may all have the same peak wavelength, or some of the wavelengths of the beams of blue light emitted by the first, second, and third light-emitting material layers EL 11 , EL 12 , and EL 13  may differ. Alternatively, the first, second, and third light-emitting material layers EL 11 , EL 12 , and EL 13  may emit light of different colors. In one example, each of the first, second, and third light-emitting material layers EL 11 , EL 12 , and EL 13  may emit blue or green light or may emit red light, green light, and blue light, thereby emitting white light as a whole. 
     Referring again to  FIGS. 5 and 6 , a thin-film encapsulation layer  170  is disposed on the cathode electrode CE. The thin-film encapsulation layer  170  may be disposed in common in the first emission regions LA 1 , the second emission regions LA 2 , the third emission regions LA 3 , and the non-emission region NLA. In some embodiments, the thin-film encapsulation layer  170  may directly cover the cathode electrode CE. In some embodiments, a capping layer (not illustrated), which covers the cathode electrode CE, may be further disposed between the thin-film encapsulation layer  170  and the cathode electrode CE, in which case, the thin-film encapsulation layer  170  may directly cover the capping layer. 
     In some embodiments, the thin-film encapsulation layer  170  may include a first encapsulation inorganic film  171 , an encapsulation organic film  173 , and a second encapsulation inorganic film  175 , which are sequentially deposited on the cathode electrode CE. 
     In some embodiments, the first and second encapsulation inorganic films  171  and  175  may be formed of silicon nitride, aluminum nitride, zirconium nitride, titanium nitride, hafnium nitride, tantalum nitride, silicon oxide, aluminum oxide, titanium oxide, tin oxide, cerium oxide, silicon oxynitride (SiON), or lithium fluoride. 
     In some embodiments, the encapsulation organic film  173  may be formed of an acrylic resin, a methacrylic resin, polyisoprene, a vinyl-based resin, an epoxy-based resin, a urethane-based resin, a cellulose-based resin, or a perylene-based resin. 
     The structure of the thin-film encapsulation layer  170  is not particularly limited and may vary. 
     A panel light-blocking member  190  may be positioned on the thin-film encapsulation layer  170 . The panel light-blocking member  190  may be positioned on the thin-film encapsulation layer  170 , in the non-emission region NLA. The panel light-blocking member  190  may prevent light from infiltrating between adjacent emission regions to cause color mixing, and as a result, color reproducibility can be further improved. 
     In some embodiments, the panel light-blocking member  190  may be positioned in the non-emission region NLA and may be disposed to surround the emission regions (LA 1 , LA 2 , LA 3 , LA 4 , LA 5 , and LA 6 ) in a plan view. 
     The panel light-blocking member  190  may include an organic light blocking material and may be formed by coating an organic light blocking material and subjecting the organic light blocking material to an exposure process. 
     The color converting substrate  30  will hereinafter be described. 
       FIG. 10  is a cross-sectional view taken along line X 3 -X 3 ′ of  FIGS. 3 and 4 .  FIG. 11  is a cross-sectional view taken along line X 4 -X 4 ′ of  FIGS. 3 and 4 . 
     Referring to  FIGS. 10 through 17  and further to  FIGS. 3 through 6 , the color converting substrate  30  may include a second base part  310 , a plurality of color filters ( 231 ,  232 , and  233 ), a plurality of light blocking members ( 221 ,  222 , and  227 ), the light blocking pattern  240 , the barriers  370 , a plurality of wavelength converting patterns ( 330  and  340 ), and light transmitting patterns  350 . 
     The second base part  310  may be formed of a light transmitting material. In some embodiments, the second base part  310  may include a glass substrate or a plastic substrate. In some embodiments, the second base part  310  may further include a separate layer (e.g., an insulating layer such as an inorganic film) positioned on the glass substrate or the plastic substrate. As described above, the light transmitting regions (TA 1 , TA 2 , TA 3 , TA 4 , TA 5 , and TA 6 ) and the light blocking regions BA of  FIG. 4  may be defined on the second base part  310 , and detailed descriptions thereof will be omitted. 
     The color filters ( 231 ,  232 , and  233 ), the light blocking members ( 221 ,  222 , and  227 ), and the light blocking pattern  240  may be positioned on a surface of the second base part  310  that faces the display substrate  10 . 
     The color filters ( 231 ,  232 , and  233 ) may include first color filters  231 , second color filters  232 , and third color filters  233 . 
     The first color filters  231  may be positioned on the surface of the second base part  310 , in the first light transmitting regions TA 1  and the fourth light transmitting regions TA 4 . In some embodiments, first color filters  231  positioned in the first light transmitting regions TA 1  and first color filters  231  positioned in the fourth light transmitting regions TA 4  may be connected to one another. That is, first color filters  231  positioned in the first row RT 1  may be connected to first color filters  231  positioned in the second row RT 2 . The first color filters  231  may extend in the second direction DR 2 , and ninth light blocking members  229  that will be described later may be positioned in the overlapping areas of the first color filters  231  and the ninth light blocking regions BA 9 . The ninth light blocking members  229  may divide the first light transmitting regions TA 1  and the fourth light transmitting regions TA 4  in the second direction DR 2 . 
     However, the disclosure is not limited to this. Alternatively, the first color filters  231  positioned in the first light transmitting regions TA 1  may be spaced apart from the first color filters  231  positioned in the fourth light transmitting regions TA 4 . That is, the first color filters  231  may be arranged as stripes that extend in the second direction DR 2  or as islands that are spaced apart from one another in the second direction DR 2 . 
     The first color filters  231  may selectively transmit light of the third color (e.g., red light) therethrough and may block or absorb light of the first color (e.g., blue light) and light of the second color (e.g., green light). In some embodiments, the first color filters  231  may be red color filters and may include a red colorant such as a red dye or a red pigment. The term “colorant”, as used herein, may be understood as encompassing both a dye and a pigment. 
     The second color filters  232  and the third color filters  233 , like the first color filters  231 , may also be disposed on the surface of the second base part  310 . The second color filters  232  may be positioned in the second light transmitting regions TA 2  and the fifth light transmitting regions TA 5 , and the third color filters  233  may be positioned in the third light transmitting regions TA 3  and the sixth light transmitting regions TA 6 . In some embodiments, as the second color filters  232  and the third color filters  233  extend in the second direction DR 2 , second color filters  232  positioned in the first row RT 1  and third color filters  233  positioned in the first row RT 1  may be connected to second color filters  232  positioned in the second row RT 2  and third color filters  233  positioned in the second row RT 2 . The ninth light blocking members  229  that will be described later may be positioned in the overlapping areas of the second color filters  232  and the ninth light blocking regions BA 9  and of the third color filters  233  and the ninth light blocking regions BA 9 . However, the disclosure is not limited to this. Alternatively, the second color filters  232  and the third color filters  233  may also be spaced apart between the first and second rows RT 1  and RT 2 . That is, the second color filters  232  and the third color filters  233  may also be arranged as stripes that extend in the second direction DR 2  or as islands that are spaced apart from one another in the second direction DR 2 . 
     The second color filters  232  may selectively transmit light of the second color (e.g., green light) therethrough and may block or absorb light of the first color (e.g., blue light) and light of the third color (e.g., red light). In some embodiments, the second color filters  232  may be green color filters and may include a green colorant such as a green dye or a green pigment. 
     The third color filters  233  may selectively transmit light of the first color (e.g., blue light) therethrough and may block or absorb light of the second color (e.g., green light) and light of the third color (e.g., red light). In some embodiments, the third color filters  233  may be blue color filters and may include a blue colorant such as a blue dye or a blue pigment. 
     The light blocking members  220  may be disposed on the surface of the second base part  310  that faces the display substrate  10 . The light blocking members  220  may be positioned in some of the light blocking regions BA to block the transmission of light. In some embodiments, the light blocking members  220  may be arranged substantially in a lattice shape in a plan view, as illustrated in  FIG. 13 . 
     In some embodiments, the light blocking members  220  may include an organic light blocking material and may be formed by coating an organic light blocking material and subjecting the organic light blocking material to an exposure process. External light directed to the display device  1  may distort the color reproducibility of the color converting substrate  30 . The light blocking members  220 , which are positioned on the second base part  310 , can absorb at least some of the external light. Thus, the light blocking members  220  can reduce the distortion of colors by the reflection of the external light. In some embodiments, the light blocking members  220  can prevent light from infiltrating between adjacent light transmitting regions to cause color mixing, and as a result, color reproducibility can be further improved. 
     In some embodiments, the light blocking members  220  may include first light blocking members  221 , which are positioned in the first light blocking regions BA 1 , second light blocking members  222 , which are positioned in the second light blocking regions BA 2 , fourth light blocking regions BA 4 , which are positioned in the fourth light blocking regions BA 4 , a sixth light blocking region  226 , which is positioned in the sixth light blocking region BA 6 , seventh light blocking members  227 , which are positioned in the seventh light blocking regions BA 7 , eighth light blocking members  228 , which are positioned in the eighth light blocking regions BAB, and the ninth light blocking members  229 , which are positioned in the ninth light blocking region BA 9 . In some embodiments, the first light blocking members  221 , the second light blocking members  222 , and the seventh light blocking members  227  may be connected to the ninth light blocking members  229 , and the fourth light blocking members  224 , the fifth light blocking members  225 , and the eighth light blocking members  228  may also be connected to the ninth light blocking members  229 . The light blocking members  220  may be formed to have substantially the same shape as the light blocking regions BA. 
     That is, the first light blocking members  221 , the second light blocking members  222 , the fourth light blocking members  224 , the fifth light blocking members  225 , the seventh light blocking members  227 , and the eighth light blocking members  228  may extend in the second direction DR 2 , and the ninth light blocking members  229  may extend in the first direction DR 1 . The light blocking members  220  may be substantially integrally formed into a single pattern, and the reference numerals assigned to the light blocking members  220  may be understood as being for distinguishing the light blocking members  220  from one another for their locations. 
     In some embodiments, first sides of the first color filters  231  may be positioned on the seventh light blocking members  227 , in the seventh light blocking regions BA 7 . Second sides of the first color filters  231  may be disposed on the first light blocking members  221 , in the first light blocking regions BA 1 . Similarly, first sides of the second color filters  232  may be positioned on the first light blocking members  221 , in the first light blocking regions BA 1 , and second sides of the second color filters  232  may be disposed on the second light blocking members  222 , in the second light blocking regions BA 2 . 
     In some embodiments, the first color filters  231  and the second color filters  232  may be formed as stripes that extend in the second direction DR 2  and may extend across the ninth light blocking regions BA 9 , between the first and second rows RT 1  and RT 2 . The first color filters  231  and the second color filters  232  may be positioned on the ninth light blocking members  229 , in the ninth light blocking regions BA 9 , and may be disposed to cover the ninth light blocking members  229 . However, the disclosure is not limited to this. Alternatively, the first color filters  231  and/or the second color filters  232  may be disposed to be spaced apart from the ninth light blocking region BA 9  between the first and second rows RT 1  and RT 2 , along the second direction DR 2 . That is, the first color filters  231  and the second color filters  232  may be formed as islands. 
     Meanwhile, the light blocking members  220  may not be disposed in the third and sixth light blocking regions BA 3  and BA 6 . The display device  1  may include the light blocking pattern  240 , which is positioned in at least part of the color converting substrate  30 . The light blocking pattern  240 , unlike the light blocking members  220 , may be disposed between adjacent identical light transmitting regions, for example, between the third light transmitting regions TA 3 . Accordingly, first sides of the third color filters  233 , which are disposed in the third light transmitting regions TA 3 , may be positioned on the second light blocking members  222 , in the second light blocking regions BA 2 , but second sides of the third color filters  233  may be in contact with the light blocking pattern  240  in the third light blocking region BA 3 . In some embodiments, as the light blocking pattern  240  extends in the second direction DR 2 , the light blocking patterns  240  may be disposed in the third and sixth light blocking regions BA 3  and BA 6  to form stripes. 
     The light blocking pattern  240  may perform substantially the same functions as the light blocking members  220 . That is, the light blocking pattern  240  may be positioned in the third light blocking region BA 3  to block the transmission of light. The light blocking pattern  240  can prevent beams of light emitted from adjacent identical light transmitting regions, for example, from the third light transmitting regions TA 3 , from being mixed together. 
     As will be described later, the light transmitting patterns  350 , which are disposed in adjacent third light transmitting regions TA 3 , may be connected to each other beyond the third light blocking region BA 3 . Light emitted from the third light-emitting elements ED 3  of the display substrate  10  may be released from the third light transmitting regions TA 3  through the light transmitting patterns  350  and the third color filters  233 . Here, the light blocking pattern  240 , which is positioned between the adjacent third light transmitting regions TA 3 , can prevent light from infiltrating between the light transmitting regions through the light transmitting patterns  350  to cause color mixing. As a result, the light blocking pattern  240  can improve color reproducibility. Also, the light blocking pattern  240  can absorb at least some of external light and can reduce the distortion of colors. The light blocking pattern  240  may be formed by applying laser light to the third light blocking region BA 3  after the formation of the third color filters  233  during the fabrication of the color converting substrate  30 . That is, the light blocking pattern  240  may be formed by carbonizing parts of the third color filters  233  and parts of the light transmitting patterns  350 , but the disclosure is not limited thereto. Alternatively, the light blocking pattern  240  may include an organic light blocking material and may be formed by coating an organic light blocking material and subjecting the organic light blocking material to an exposure process. This will be described later in detail. 
     A first capping layer  391 , which covers the light blocking members  220 , the first color filters  231 , the second color filters  232 , and the third color filters  233 , may be positioned on the surface of the second base part  310 . In some embodiments, the first capping layer  391  may be in direct contact with the first color filters  231 , the second color filters  232 , and the third color filters  233 . 
     The first capping layer  391  may be in contact with the light blocking members  220 . In some embodiments, in the first light blocking regions BA 1 , the first light blocking members  221  may be in direct contact with the first capping layer  391 . Also, in the second light blocking regions BA 2 , the second light blocking members  222  may be in contact with the first capping layer  391 , and in the seventh light blocking regions BA 7 , the seventh light blocking members  227  may be in contact with the first capping layer  391 . Also, in the ninth light blocking regions BA 9 , the ninth light blocking members  229  may be in direct contact with the first capping layer  391 . Meanwhile, the light blocking pattern  240  that will be described later may be disposed in the third light blocking region BA 3  and may be formed by carbonizing part of the first capping layer  391  with laser light. That is, the first capping layer  391  may be disposed on the entire surface of the second base part  310 , but may be divided in part by the third light blocking region BA 3 . 
     The first capping layer  391  may prevent the light blocking members  220 , the first color filters  231 , the second color filters  232 , and the third color filters  233  from being damaged or contaminated by impurities from the outside such as moisture or the air. Also, the first capping layer  391  may prevent the colorants from the first color filters  231 , the second color filters  232 , and the third color filters  233  from diffusing into elements other than the first color filters  231 , the second color filters  232 , and the third color filters  233 , such as, for example, first wavelength converting patterns  330  and second wavelength converting patterns  340 . In some embodiments, the first capping layer  391  may be formed of an inorganic material. For example, the first capping layer  391  may include silicon nitride, aluminum nitride, zirconium nitride, titanium nitride, hafnium nitride, tantalum nitride, silicon oxide, aluminum oxide, titanium oxide, tin oxide, cerium oxide, or silicon oxynitride. 
     The barriers  370  may be positioned in some of the light blocking regions BA and may overlap with the non-emission region NLA in the plan view. The barriers  370  may be disposed to surround the first light transmitting regions TA 1 , the second light transmitting regions TA 2 , the fourth light transmitting regions TA 4 , and the fifth light transmitting regions TA 5 . In some embodiments, the barriers  370  may form a lattice shape in a plan view. 
     The first wavelength converting patterns  330 , the second wavelength converting patterns  340 , and the light transmitting patterns  350  that will be described later may be formed by inkjet printing using an ink composition. The barriers  370 , which are formed in the color converting substrate  30 , may guide the ink composition for forming the first wavelength converting patterns  330 , the second wavelength converting patterns  340 , and the light transmitting patterns  350 , such that the ink composition can be stably placed at any desired location. 
     In some embodiments, the barriers  370  may be formed of an organic material, particularly, a photosensitive organic material. The photosensitive organic material may be a negative photosensitive material that is cured when illuminated with light, but the disclosure is not limited thereto. Also, in some embodiments, the barriers  370  may further include light blocking members. That is, the barriers  370  may be positioned in the light blocking regions BA to block the transmission of light. Specifically, the barriers  370  may be positioned between the first wavelength converting patterns  330  and the second wavelength converting patterns  340  and between the second wavelength converting patterns  340  and the light transmitting patterns  350 . The barriers  370  may prevent beams of light emitted from adjacent different light transmitting regions from being mixed together. 
     The first wavelength converting patterns  330 , the second wavelength converting patterns  340 , and the light transmitting patterns  350  may be disposed on the first capping layer  391 . In some embodiments, the first wavelength converting patterns  330 , the second wavelength converting patterns  340 , and the light transmitting patterns  350  may be formed by inkjet printing, but the disclosure is not limited thereto. In other embodiments, the light transmitting patterns  350 , the first wavelength converting patterns  330 , and the second wavelength converting patterns  340  may be formed by applying a photosensitive material and exposing and developing the photosensitive material. The light transmitting patterns  350 , the first wavelength converting patterns  330 , and the second wavelength converting patterns  340  will hereinafter be described as being formed by inkjet printing. 
     The first wavelength converting patterns  330  may be positioned on the first capping layer  391 , in the first light transmitting regions TA 1  and the fourth light transmitting regions TA 4 . In some embodiments, the first wavelength converting patterns  330  may be formed as stripes that extend in the second direction DR 2  and may extend across the ninth light blocking region BA 9  between the first and second rows RT 1  and RT 2 , but the disclosure is not limited thereto. In other embodiments, the first wavelength converting patterns  330  may be formed as islands that are spaced apart between the first light transmitting regions TA 1  and the fourth light transmitting regions TA 4 . 
     The first wavelength converting patterns  330  may convert or shift convert the peak wavelength of incident light into a particular peak wavelength. In some embodiments, the first wavelength converting patterns  330  may convert emission light L provided by the first light-emitting elements ED 1  into red light having a peak wavelength of about 610 nm to about 650 nm and may emit the red light. 
     In some embodiments, the first wavelength converting patterns  330  may include a first base resin  331  and a first wavelength converting material  335 , which is dispersed in the first base resin  331 , and may further include a first scatterer  333 , which is dispersed in the first base resin  331 . The first base resin  331  may be formed of a material having a high light transmittance. In some embodiments, the first base resin  331  may be formed of an organic material. In some embodiments, the first base resin  331  may include an organic material such as an epoxy resin, an acrylic resin, a cardo resin, or an imide resin, but the disclosure is not limited thereto. 
     The first wavelength converting material  335  may convert or shift the peak wavelength of incident light into a particular peak wavelength. In some embodiments, the first wavelength converting material  335  may convert the emission light L provided by the first light-emitting elements ED 1  into red light having a single peak wavelength of about 610 nm to about 650 nm and may emit the red light. 
     Examples of the first wavelength converting material  335  include quantum dots, quantum rods, and a phosphor. In one example, the quantum dots may be a particulate material that emits light of a particular color in response to the electrons transitioning from the conduction band to the valance band. 
     The quantum dots may be a semiconductor nanocrystal material. Since the quantum dots have a predetermined band gap depending on their composition and size, the quantum dots absorb light and emit light of a predetermined wavelength. The semiconductor nanocrystal material includes a group IV element, a group II-VI compound, a group III-V compound, a group IV-VI compound, and a combination thereof. 
     The group II-VI compound may be selected from the group consisting of: a binary compound selected from among CdSe, CdTe, ZnS, ZnSe, ZnTe, ZnO, HgS, HgSe, HgTe, MgSe, MgS, and a mixture thereof; a ternary compound selected from among InZnP, AgInS, CuInS, CdSeS, CdSeTe, CdSTe, ZnSeS, ZnSeTe, ZnSTe, HgSeS, HgSeTe, HgSTe, CdZnS, CdZnSe, CdZnTe, CdHgS, CdHgSe, CdHgTe, HgZnS, HgZnSe, HgZnTe, MgZnSe, MgZnS, and a mixture thereof; or a quaternary compound selected from among HgZnTeS, CdZnSeS, CdZnSeTe, CdZnSTe, CdHgSeS, CdHgSeTe, CdHgSTe, HgZnSeS, HgZnSeTe, HgZnSTe, and a mixture thereof. 
     The group III-V compound may be selected from the group consisting of: a binary compound selected from among GaN, GaP, GaAs, GaSb, AlN, AlP, AlAs, AlSb, InN, InP, InAs, InSb, and a mixture thereof; a ternary compound selected from among GaNP, GaNAs, GaNSb, GaPAs, GaPSb, AlNP, AINAs, AlNSb, AlPAs, AlPSb, InGaP, InNP, InAiP, InNAs, InNSb, InPAs, InPSb, GaAlNP, and a mixture thereof; and a quaternary compound selected from among GaAlNAs, GaAlNSb, GaAlPAs, GaAlPSb, GaInNP, GaInNAs, GaInNSb, GaInPAs, GaInPSb, InAlNP, InAlNAs, InAlNSb, InAlPAs, InAlPSb, and a mixture thereof. 
     The group IV-VI compound may be selected from the group consisting of: a binary compound selected from among SnS, SnSe, SnTe, PbS, PbSe, PbTe, and a mixture thereof; a ternary compound selected from among SnSeS, SnSeTe, SnSTe, PbSeS, PbSeTe, PbSTe, SnPbS, SnPbSe, SnPbTe, and a mixture thereof; and a quaternary compound selected from among SnPbSSe, SnPbSeTe, SnPbSTe, and a mixture thereof. The group IV element may be selected from the group consisting of Si, Ge, and a mixture thereof. The group IV compound may be a binary compound selected from among SiC, SiGe, and a mixture thereof. 
     These binary, ternary, or quaternary compounds may exist in a uniform concentration or in a partially different concentration in particles. The quantum dots may have a core-shell structure in which one quantum dot surrounds another quantum dot. The interfaces between the cores and the shells of the quantum dots may have a concentration gradient in which the concentration of the element(s) in the shells of the quantum dots gradually decreases toward the centers of the shells of the quantum dots. 
     In some embodiments, the quantum dots may have a core-shell structure consisting of a core including the above-described semiconductor nanocrystal material and a shell surrounding the core. The shells of the quantum dots may serve as protective layers for maintaining the semiconductor characteristics of the quantum dots by preventing chemical denaturation of the cores of the quantum dots and/or as charging layers for imparting electrophoretic characteristics to the quantum dots. The shells of the quantum dots may have a single-layer structure or a multilayer structure. The interfaces between the cores and the shells of the quantum dots may have a concentration gradient in which the concentration of the element(s) at the shells of the quantum dots gradually decreases toward the centers of the shells of the quantum dots. The shells of the quantum dots may include a metal or non-metal oxide, a semiconductor compound, or a combination thereof. 
     In one example, the metal or non-metal oxide may be a binary compound such as SiO 2 , Al 2 O 3 , TiO 2 , ZnO, MnO, Mn 2 O 3 , Mn 3 O 4 , CuO, FeO, Fe 2 O 3 , Fe 3 O 4 , CoO, Co 3 O 4 , or NiO or a ternary compound such as MgAl 2 O 4 , CoFe 2 O 4 , NiFe 2 O 4 , or CoMn 2 O 4 , but the disclosure is not limited thereto. 
     In one example, the semiconductor compound may be CdS, CdSe, CdTe, ZnS, ZnSe, ZnTe, ZnSeS, ZnTeS, GaAs, GaP, GaSb, HgS, HgSe, HgTe, InAs, InP, InGaP, InSb, AlAs, AlP, or AlSb, but the disclosure is not limited thereto. 
     Light emitted by the first wavelength converting material  335  may have a full width at half maximum (“FMHM”) of about 45 nm or less, about 40 nm or less, or about 30 nm or less, and thus, the purity of colors displayed by the display device  1  and the color reproducibility of the display device  1  can be further improved. Also, the first wavelength converting material  335  can emit light in various directions regardless of the incidence direction of the light. The side visibility of the third color displayed in the first light transmitting regions TA 1  can be improved. 
     Some of the emission light L provided by the first light-emitting elements ED 1  may not be converted into red light by the first wavelength converting material  335 , but may be emitted through the first wavelength converting patterns  330 . Components of the emission light L that are incident upon the first color filters  231  without being converted by the first wavelength converting patterns  330  may be blocked by the first color filters  231 . On the contrary, red light obtained from the emission light L by the first wavelength converting patterns  330  may be emitted to the outside through the first color filters  231 . That is, light emitted form the first light transmitting regions TA 1  may be red light. 
     The first scatterer  333  may have a different refractive index from the first base resin  331  and may form an optical interface with the first base resin  331 . In one example, the first scatterer  333  may include light-scattering particles. The material of the first scatterer  333  is not particularly limited as long as it can scatter at least some light, and the first scatterer  333  may include, for example, particles of a metal oxide or particles of an organic material. The metal oxide may be titanium oxide (TiO 2 ), zirconium oxide (ZrO 2 ), aluminum oxide (Al 2 O 3 ), indium oxide (In 2 O 3 ), zinc oxide (ZnO), or tin oxide (SnO 2 ), and the organic material may be an acrylic resin or a urethane resin. The first scatterer  333  may scatter light in random directions, regardless of the incident direction of the light, without substantially changing the wavelength of light passing through the first wavelength converting patterns  330 . 
     The second wavelength converting patterns  340  may be positioned on the first capping layer  391 , in the second light transmitting regions TA 2  and the fifth light transmitting regions TA 5 . In some embodiments, the second wavelength converting patterns  340  may be formed as stripes that extend in the second direction Dr 2  and may extend across the ninth light blocking region BA 9  between the first and second rows RT 1  and RT 2 , but the disclosure is not limited thereto. In other embodiments, the second wavelength converting patterns  340  may be formed as islands that are spaced apart between the second light transmitting regions TA 2  and the fifth light transmitting regions TA 5 . 
     The second wavelength converting patterns  340  may convert or shift convert the peak wavelength of incident light into a particular peak wavelength. In some embodiments, the second wavelength converting patterns  340  may convert emission light L provided by the second light-emitting elements ED 2  into green light having a peak wavelength of about 510 nm to about 550 nm and may emit the green light. 
     In some embodiments, the second wavelength converting patterns  340  may include a second base resin  341  and a second wavelength converting material  345 , which is dispersed in the second base resin  341 , and may further include a second scatterer  343 , which is dispersed in the second base resin  341 . 
     The second base resin  341  may be formed of a material having a high light transmittance. In some embodiments, the second base resin  341  may be formed of an organic material. In some embodiments, the second base resin  341  may be formed of the same material as the first base resin  331  or may include at least one of the above-described materials for the first base resin  331 , but the disclosure is not limited thereto. 
     The second wavelength converting material  345  may convert or shift the peak wavelength of incident light into a particular peak wavelength. In some embodiments, the second wavelength converting material  345  may convert blue light having a peak wavelength of 440 nm to 480 nm into green light having a peak wavelength of 510 nm to 550 nm. 
     Examples of the second wavelength converting material  345  include quantum dots, quantum rods, and a phosphor. The second wavelength converting material  345  is substantially the same as the first wavelength converting material  335 , and thus, a detailed description thereof will be omitted. 
     In some embodiments, the first and second wavelength converting materials  335  and  345  may both be formed of quantum dots. In this case, the particle size of the first wavelength converting material  335  may be greater than the particle size of the second wavelength converting material  345 . 
     The second scatterer  343  may have a different refractive index from the second base resin  341  and may form an optical interface with the second base resin  341 . In one example, the second scatterer  343  may include light-scattering particles. The second scatterer  343  is substantially the same as the first scatterer  333 , and thus, a detailed description thereof will be omitted. 
     The emission light L emitted by the second light-emitting elements ED 2  may be provided to the second wavelength converting patterns  340 , and the second wavelength converting material  345  may convert the emission light L provided by the second light-emitting elements ED 2  into green light having a peak wavelength of about 510 nm to about 550 nm and emit the green light. 
     The light transmitting patterns  350  may be positioned on the first capping layer  391 , in the third light transmitting regions TA 3  and the sixth light transmitting regions TA 6 . In some embodiments, the light transmitting patterns  350  may be formed as stripes that extend in the second direction DR 2  and may extend across the ninth light blocking region BA 9  between the first and second rows RT 1  and RT 2 , but the disclosure is not limited thereto. In other embodiments, the light transmitting patterns  350  may be formed as islands that are spaced apart between the third light transmitting regions TA 3  and the sixth light transmitting regions TA 6 . 
     Also, the light transmitting patterns  350  may be positioned in the adjacent third light transmitting regions TA 3 . In one example, a light transmitting pattern  350  positioned in one third light transmitting region TA 3  may be connected to a light transmitting pattern  350  positioned in another third light transmitting region TA 3 , thereby forming a single light transmitting pattern  350  together. The light transmitting patterns  350  may also be positioned in the third light blocking region BA 3  and may have a larger width than a width of each of the first wavelength converting patterns  330  and the second wavelength converting patterns  340 . As described above, the light blocking pattern  240  may be disposed in the third light blocking region BA 3 , between the adjacent third light transmitting regions TA 3 . Accordingly, even though the light transmitting patterns  350  are disposed in and across the adjacent third light transmitting regions TA 3 , light incident upon the light transmitting patterns  350  from one third light-emitting element ED 3  may be emitted to a third light transmitting region TA 3  corresponding to the third light-emitting element ED 3 , but not to a third light transmitting region TA 3  corresponding to a neighboring third light-emitting element ED 3 . That is, the light blocking pattern  240  can prevent beams of light incident upon the light transmitting patterns  350  from being emitted to other light transmitting regions, for example, other third light transmitting regions TA 3  that do not correspond to an arbitrary third light-emitting element ED 3 . 
     In one example, a thickness TH 240  of the light transmitting patterns  240  in the third direction DR 3  (i.e., thickness direction of the color converting substrate  30 ) may be greater than a thickness TH 220  of the light blocking members  220 , but smaller than the thickness of the barriers  370 . As will be described later, the light blocking pattern  240  may be formed by applying laser light to the third light blocking region BA 3  during the fabrication of the color converting substrate  30 . The light blocking pattern  240  may be formed by carbonizing parts of the light transmitting patterns  350 , the third color filters  233 , and the first capping layer  391  in the third light blocking region BA 3  with the laser light. Here, the light blocking pattern  240  may have a sufficient thickness to prevent light incident upon the light transmitting patterns  350  from the third light-emitting elements ED 3  to other third light transmitting regions TA 3  that do not correspond to the third light transmitting elements ED 3 . The thickness TH 240  of the light blocking pattern  240  may be smaller than the thickness of the barriers  370 , but greater than the thickness TH 220  of the light blocking members  220 . In one example, the thickness TH 240  of the light blocking pattern  240  may be less than half the thickness of the barriers  370 , but the disclosure is not limited thereto. 
     The light transmitting patterns  350  may transmit incident light therethrough. Emission light L provided by the third light-emitting elements ED 3  may be emitted to the outside of the display device  1  through the light transmitting patterns  350  and the third color filters  233 . That is, light emitted from the third light transmitting regions TA 3  may be blue light. 
     In some embodiments, the light transmitting patterns  350  may include a third base resin  351  and may further include a third scatterer  353 , which is dispersed in the third base resin  351 . 
     The third base resin  351  may be formed of a material having a high light transmittance. In some embodiments, the third base resin  351  may be formed of an organic material. In some embodiments, the third base resin  351  may be formed of the same material as the first base resin  331  or may include at least one of the above-described materials for the first base resin  331 , but the disclosure is not limited thereto. 
     The third scatterer  353  may have a different refractive index from third base resin  351  and may form an optical interface with the third base resin  351 . In one example, the third scatterer  353  may include light-scattering particles. The third scatterer  353  is substantially the same as the first scatterer  333 , and thus, a detailed description thereof will be omitted. 
     A second capping layer  393  may be positioned on the light transmitting patterns  350 , the first wavelength converting patterns  330 , and the second wavelength converting patterns  340 . The second capping layer  393  may cover and seal the light transmitting patterns  350 , the first wavelength converting patterns  330 , the second wavelength converting patterns  340 , and the barriers  370 . As a result, the light transmitting patterns  350 , the first wavelength converting patterns  330 , and the second wavelength converting patterns  340  can be prevented from being damaged or polluted by impurities from the outside such as moisture or the air. In some embodiments, the second capping layer  393  may be formed of an inorganic material. In some embodiments, the second capping layer  393  may be formed of the same material as the first capping layer  391  or may include at least one of the above-described materials for the first capping layer  391 , but the disclosure is not limited thereto. 
     As described above, the filler  70  may be positioned in the space between the color converting substrate  30  and the display substrate  10 . In some embodiments, the filler  70  may be positioned between the second capping layer  393  and the thin-film encapsulation layer  170 . In some embodiments, the filler  70  may be in direct contact with the second capping layer  393 . 
     As described above, the light blocking members  220 , the light blocking pattern  240 , and the barriers  370  may be disposed in the light blocking regions BA of the color converting substrate  30 . However, the barriers  370 , the light blocking members  220 , and the light blocking pattern  240  may be disposed only in some of the light blocking regions BA. The light blocking members  220 , the light blocking pattern  240 , and the barriers  370 , which are disposed in the color converting substrate  30 , and the light transmitting regions TA will hereinafter be described in further detail. 
       FIG. 12  is a plan view illustrating the arrangement of barriers in a color converting substrate according to an embodiment of the disclosure.  FIG. 13  is a plan view illustrating the arrangement of light blocking members in the color converting substrate according to an embodiment of the disclosure.  FIG. 14  is a plan view illustrating the arrangement of a light blocking pattern in the color converting substrate according to an embodiment of the disclosure.  FIG. 15  is a cross-sectional view taken along line X 5 -X 5 ′ of  FIGS. 3 and 4 .  FIG. 16  is a cross-sectional view taken along line X 6 -X 6 ′ of  FIGS. 3 and 4 .  FIG. 17  is a cross-sectional view taken along line X 7 -X 7 ′ of  FIGS. 3 and 4 . 
       FIG. 15  is a cross-sectional view taken across part of a ninth light blocking region BA 9  of the color converting substrate  30 ,  FIG. 16  is a cross-sectional view taken across parts of third and sixth light transmitting regions TA 3  and TA 6 , and  FIG. 17  is a cross-sectional view taken across second and fifth light transmitting regions TA 2  and TA 5 . 
     Referring to  FIGS. 12 through 17  and further to  FIGS. 5 and 6 , the barriers  370  may extend in the second direction DR 2  on the color converting substrate  30 . As described above, the barriers  370  may be disposed in all the light blocking regions BA except for the third and sixth light blocking regions BA 3  and BA 6 . The barriers  370  may not be disposed in a portion of the ninth light blocking region BA 9  between the adjacent light transmitting regions TA in the second direction DR 2 , for example, between the first light transmitting regions TA 1  and the fourth light transmitting regions TA 4 , between the second light transmitting regions TA 2  and the fifth light transmitting regions TA 5 , and between the third and sixth light transmitting regions TA 3  and TA 6 . As a result, the first color filters  231 , the second color filters  232 , the third color filters  233 , the first wavelength converting patterns  330 , the second wavelength converting patterns  340 , and the light transmitting patterns  350  may disposed to extend through the adjacent light transmitting regions TA in the second direction DR 2  on the color converting substrate  30 , i.e., may be formed as stripes. 
     As illustrated in  FIGS. 15 through 17 , the first color filters  231 , the second color filters  232 , the third color filters  233 , the first wavelength converting patterns  330 , the second wavelength converting patterns  340 , and the light transmitting patterns  350  may be positioned in the ninth light blocking regions BA 9 . Parts of the display substrate  10  that overlap with the ninth light blocking regions BA 9  in the plan view may correspond to the non-emission region NLA where the light-emitting elements ED are not disposed, and in the non-emission region NLA, the panel light-blocking member  190  of the display substrate  10  may be disposed to extend. 
     However, the disclosure is not limited to this. Alternatively, the barriers  370  may be disposed to extend in the first direction DR 1  on the ninth light blocking regions BA 9 . In this case, the first color filters  231 , the second color filters  232 , the third color filters  233 , the first wavelength converting patterns  330 , the second wavelength converting patterns  340 , and the light transmitting patterns  350  of the first row RL 1  may be spaced apart from those of the second row RL 2  in the second direction DR 2  on the color converting substrate  30 , i.e., may be formed as islands. 
     The first wavelength converting patterns  330  may be disposed in the first light transmitting regions TA 1  and the fourth light transmitting regions TA 4 , among spaces defined by the barriers  370 . The second wavelength converting patterns  340  may be disposed in the second light transmitting regions TA 2  and the fifth light transmitting regions TA 5 , among the spaces defined by the barriers  370 . The light transmitting patterns  350  may be disposed in the third and sixth light transmitting regions TA 3  and TA 6 , among the spaces defined by the barriers  370 . 
     The light blocking members  220  and the light blocking pattern  240  may be disposed in the light blocking regions BA and may form a single lattice pattern together. As illustrated in  FIG. 13 , the light blocking members  220  may be positioned in regions other than the third and sixth light blocking regions BA 3  and BA 6  and parts of the ninth light blocking regions BA 9 . The light blocking pattern  240  may be positioned in regions where the light blocking members  220  are not disposed, i.e., in the third and sixth light blocking regions BA 3  and BA 6  where identical light-transmitting regions are disposed adjacent to one another and in parts of the ninth light blocking regions BA 9 . The light blocking members  220  and the light blocking pattern  240  may be positioned to surround the light transmitting regions TA. 
     In one example, the color converting substrate  30  may include first-type light transmitting regions having the light blocking members  220  disposed on both sides thereof and second-type light transmitting regions having the light blocking members  220  positioned on one side thereof and the light blocking pattern  240  disposed on the other side thereof. As described above, the color converting substrate  30  may include the first light transmitting regions TA 1 , the second light transmitting regions TA 2 , and the third light transmitting regions TA 3 , which are positioned in the first row RT 1 , and may include the first region where the first light transmitting regions TA 1 , the second light transmitting regions TA 2 , and the third light transmitting regions TA 3  are arranged in the order of first second, and third light transmitting regions TA 1 , TA 2 , and TA 3  and the second region where the first light transmitting regions TA 1 , the second light transmitting regions TA 2 , and the third light transmitting regions TA 3  are arranged in the order of third, second, and first light transmitting regions TA 3 , TA 2 , and TA 1 . The light blocking members  220  may be disposed in some of the light blocking regions BA between the first light transmitting regions TA 1 , the second light transmitting regions TA 2 , and the third light transmitting regions TA 3 . 
     At least some of the first light transmitting regions TA 1 , the second light transmitting regions TA 2 , and the third light transmitting regions TA 3 , for example, the first light transmitting regions TA 1  and the second light transmitting regions TA 2 , may have the light blocking members  220  disposed on both sides thereof. That is, the first light transmitting regions TA 1  and the second light transmitting regions TA 2  may be first-type light transmitting regions. As illustrated in  FIGS. 5, 6, and 11 , the first light transmitting regions TA 1  and the second light transmitting regions TA 2  may have the light blocking members  220  and the barriers  370  disposed on both sides thereof in a cross-sectional view. Accordingly, the first color filters  231 , the second color filters  232 , the first wavelength converting patterns  330 , and the second wavelength converting patterns  340  may also have the light blocking members  220  or the barriers  370  disposed on both sides thereof. 
     Meanwhile, in the first row RT 1  of the color converting substrate  30 , the third light blocking region BA 3  may be positioned between the first region where the first light transmitting regions TA 1 , the second light transmitting regions TA 2 , and the third light transmitting regions TA 3  are arranged in the order of first, second, and third light transmitting regions TA 1 , TA 2 , and TA 3  and the second region where the first light transmitting regions TA 1 , the second light transmitting regions TA 2 , and the third light transmitting regions TA 3  are arranged in the order of third, second, and first light transmitting regions TA 3 , TA 2 , and TA 1 . In one example, the barriers  370  and the light blocking members  220  are not provided in the third light blocking region BA 3 , and the light blocking pattern  240  may be positioned in the third light blocking region BA 3 . Accordingly, the third light transmitting regions TA 3  may have the light blocking members  220  disposed on one side thereof and the light blocking pattern  240  on the other side thereof. That is, the third light transmitting regions TA 3  may be second-type light transmitting regions. As illustrated in  FIGS. 5, 6, and 10 , the third light transmitting regions TA 3  may have the light blocking members  220  and the barriers  370  disposed on one side thereof and may have only the light blocking pattern  240  disposed on the other side thereof. Accordingly, the third color filters  233  may have the light blocking members  220  disposed on one side thereof and the light blocking pattern  240  disposed on the other side thereof. On the contrary, the light transmitting patterns  350  may have the barriers  370  disposed on both sides thereof and may overlap with the light blocking pattern  240  in the plan view. That is, the light transmitting patterns  350  may be positioned in and across adjacent third light blocking regions BA 3 . In other words, the light transmitting patterns  350  in the adjacent third light transmitting regions TA 3  may be connected to each other and may thus be integrated. 
     In one example, at least parts of the light transmitting patterns  350  may overlap with the light blocking pattern  240  in the plan view. The light transmitting patterns  350  may be disposed to overlap with one or more light transmitting regions that are arranged in the first direction DR 1 . The light blocking pattern  240  may be disposed in an area where one or more light transmitting regions are disposed adjacent to each other, and the light transmitting patterns  350  may overlap with, and cover, the light transmitting pattern  240  in the plan view. In one example, the width of the light transmitting patterns  350  may be greater than each of the widths of the first light wavelength converting patterns  330  and the second wavelength converting patterns  340 . 
     However, the disclosure is not limited to this. Alternatively, the light transmitting pattern  240  may be positioned in a light blocking region other than the third light blocking region BA 3  where the third light transmitting regions TA 3  are disposed adjacent to each other, for example, in the seventh light blocking region BA 7  where the first light transmitting regions TA 1  and other first light transmitting regions TA 1  are disposed adjacent to one another. In this case, the color converting substrate  30  may include the second light transmitting regions TA 2  as first-type light transmitting regions and the first light transmitting regions TA 1  and the third light transmitting regions TA 3  as second-type light transmitting regions. Accordingly, the first wavelength converting patterns  330  may also overlap with, and cover, the light blocking pattern  240  in the plan view. Also, the light blocking pattern  240  may be disposed in the ninth light blocking regions BA 9  to extend in the first direction DR 1 . Various other embodiments of the arrangement of the light transmitting pattern  240  will be described later. 
     The shape of the light blocking pattern  240  may be obtained by arranging some of the light transmitting regions TA adjacent to their respective identical light transmitting regions TA and not providing the barriers  370  between adjacent identical light transmitting regions TA, during the fabrication of the color converting substrate  30 . In a case where the first wavelength converting patterns  330 , the second wavelength converting patterns  340 , and the light transmitting patterns  350  are formed by inkjet printing, ink needs to be sprayed into areas corresponding to the light transmitting regions TA. A small amount of ink may be sprayed into light transmitting regions having a relatively small area, such as the third light transmitting regions TA 3 . In the color converting substrate  30 , identical light transmitting regions may be arranged adjacent to one another, and the barriers  370  may not be provided between the adjacent identical light transmitting regions. As identical light transmitting regions having a relatively small area are disposed adjacent to one another, ink can be sprayed into the adjacent identical light transmitting regions at the same time, and as a result, the impact precision of ink required for ink to be precisely mounted in each light transmitting region TA can be lowered. Accordingly, during the fabrication of the color converting substrate  30  through inkjet printing, the impact precision of ink can be improved, and the distribution of inkjet printing processes using multiple nozzles can be improved. The fabrication of the color converting substrate  30  will hereinafter be described. 
       FIGS. 18 through 23  are cross-sectional views illustrating processes of the fabrication of a display device according to an embodiment of the disclosure. 
       FIGS. 18 through 23  illustrate how to fabricate the color converting substrate  30  of the display device  1 .  FIGS. 18 through 23  illustrate a second light transmitting region TA 2  and two adjacent third light transmitting regions TA 3 . That is, the fabrication of the color converting substrate  30  will hereinafter be described, taking one first-type light transmitting region and two second-type light transmitting regions. However, the description that follows may also be applicable to other light transmitting regions TA, for example, the first light transmitting regions TA 1 , the fourth light transmitting regions TA 4 , the fifth light transmitting regions TA 5 , the sixth light transmitting regions TA 6 . 
     Referring to  FIGS. 18 through 23 , the light blocking members  220  are formed on the surface of the second base part  310 , as illustrated in  FIG. 18 . The light blocking members  220  are arranged as already described above. The light blocking members  220 , which are disposed on the surface of the second base part  310 , may include first light blocking members  221 , which are positioned in the first light blocking regions BA 1 , and second light blocking regions BA 2 , which are positioned in the second light blocking regions BA 2 . As described above, the light blocking members  220  may not be disposed in the third light blocking regions BA 3 . The light blocking members  220  may form a lattice pattern on the surface of the second base part  310 . 
     Thereafter, as illustrated in  FIG. 19 , the color filters  230  are formed on the surface of the second base part  310 , between the light blocking members  220 . The color filters  230  may be formed in areas that overlap with the light transmitting regions TA in the plan view. The color filters  230  may be formed by applying a photosensitive organic material including a particular colorant and exposing and developing the photosensitive organic material. In one example, the first color filters  231  may be formed by applying a photosensitive organic material including a red colorant and exposing and developing the photosensitive organic material including the red colorant, the second color filters  232  may be formed by applying a photosensitive organic material including a green colorant and exposing and developing the photosensitive organic material including the green colorant, and the third color filters  233  may be formed by applying a photosensitive organic material including a blue colorant and exposing and developing the photosensitive organic material including the blue colorant. 
     The second color filters  232  may be formed between the first light blocking members  221  and the second light blocking members  222 , and the third color filters  233  may be formed in the third light transmitting regions BA 3  between the second light blocking members  222 . The first sides and the second sides of the second color filers  232  may be positioned on the first light blocking members  221  and the second light blocking members  222 . The first sides of the third color filters  233  may be disposed on the second light blocking members  222 , and the second sides of the third color filters  233  may be disposed on the second base part  310 . The third color filters  233  are illustrated as being formed to be spaced apart from each other in the third light blocking region BA 3 , but the disclosure is not limited thereto. Alternatively, third color filters  233  disposed in the adjacent third light transmitting regions TA 3  may be integrally formed. 
     Thereafter, as illustrated in  FIG. 20 , the first capping layer  391 , which covers the second color filters  232 , the third color filters  233 , the first light blocking members  221 , and the second light blocking members  222 , is formed, and the barriers  370  are formed in the first light blocking regions BA 1  and the second light blocking regions BA 2 . The arrangements and the shapes of the barriers  370  and the first capping layer  391  are as already described above. The barriers  370  may not be disposed in the third light blocking region BA 3  where the third light transmitting regions TA 3  are disposed adjacent to each other. In the third light blocking region BA 3 , the first capping layer  391  may be in part in contact with the second base part  310 , but the disclosure is not limited thereto. Alternatively, in a case where the third color filters  233  are integrally formed, the first capping layer  391  may not be in contact with the second base part  310 , in the third light blocking region BA 3 . 
     Thereafter, as illustrated in  FIGS. 21 and 22 , the second wavelength converting patterns  340  and the light transmitting patterns  350  are formed by spraying ink into the second light transmitting regions TA 2  and the third light transmitting regions TA 3 . The second wavelength converting patterns  340  and the light transmitting patterns  350  may be formed in areas surrounded by the barriers  370 . As described above, each of the second wavelength converting patterns  3   s   40  may be formed in one second light transmitting region TA 2  surrounded by the barriers  370 . The light transmitting patterns  350  may be formed in two adjacent third light transmitting regions TA 3  and the third light blocking region BA 3  surrounded by the barriers  370 . As illustrated, the second wavelength converting patterns  340  may be sprayed into their respective second light transmitting regions TA 2  through single nozzles, and the light transmitting patterns  350  may be sprayed into the two adjacent third light transmitting regions TA 3  through two nozzles at the same time. A third width WT 3  of the third light transmitting regions TA 3  may be smaller than a second width WT 2  of the second light transmitting regions TA 2 , and a small amount of ink may be sprayed into each of the third light transmitting regions TA 3 . However, in the display device  1 , as the barriers  370  are not provided between the two adjacent third light transmitting regions TA 3 , a relatively large amount of ink can be sprayed into the two adjacent third light transmitting regions TA 3  at the same time. As a result, the impact precision of ink can be improved during the fabrication of the color converting substrate  30 , and the distribution of inkjet processes using multiple nozzles can be improved by simplifying the fabrication of the color converting substrate  30 . 
     After the formation of the light transmitting patterns  350 , the light blocking pattern  240  is formed by applying laser light to parts LIA of the light transmitting patterns  350  positioned in the third light blocking region BA 3 . The laser light may be applied to the parts LIA in the third light blocking region BA 3 , and parts of the light transmitting patterns  350 , the third color filters  233 , and the first capping layer  391  may be carbonized by the laser light. The light blocking pattern  240  may be formed in an area carbonized by the laser light. 
     In one example, the laser light may be applied from below the other surface of the second base part  310  that is opposite to the surface of the second base part  310  where the light transmitting patterns  350  are formed. That is, the laser light may be applied from below the other surface of the second base part  310  to the light transmitting patterns  350 , passing through the other surface of the second base part  310 , and the light blocking pattern  240  may be formed directly on the surface of the second base part  310 . As described above, the light blocking pattern  240  may be disposed between the adjacent third light transmitting regions TA 3  to prevent color mixing therebetween. However, the light blocking pattern  240  may not necessarily be formed on the surface of the second base part  310 . Alternatively, the laser light may be applied from above the surface of the second base part  310 , and the light blocking pattern  240  may be formed to be spaced apart from the second base part  310 . This will be described later in detail. 
     Thereafter, as illustrated in  FIG. 23 , the second capping layer  393  is formed to cover the second wavelength converting patterns  340 , the barriers  370 , and the light transmitting patterns  350 , and the display substrate  10  and the color converting substrate  30  are bonded together, thereby obtaining the display device  1 . In one example, during the fabrication of the color converting substrate  30 , the barriers  370  may not be provided between adjacent identical light transmitting regions, for example, between the third light transmitting regions TA 3 , and the light transmitting patterns  350  may be integrally formed in the third light transmitting regions TA 3  and the third light blocking region BA 3  at the same time. The light transmitting patterns  350  may be disposed in two adjacent third light transmitting regions TA 3  and the third light blocking region BA 3  between the two adjacent third light transmitting regions TA 3  and may overlap with the light blocking pattern  240 , in the third light blocking region BA 3 . Accordingly, during the fabrication of the color converting substrate  30 , the impact precision of ink for forming the light transmitting patterns  350  can be improved, and the distribution of inkjet printing processes using multiple nozzles can be improved. Also, the light blocking pattern  240  can be formed in the third light blocking region BA 3  near the two adjacent third light transmitting regions TA 3  and can prevent color mixing between the two adjacent third light transmitting regions TA 3 . 
     A color converting substrate  30  of a display device  1  according to another embodiment of the disclosure will hereinafter be described. 
       FIG. 24  is a plan view illustrating the arrangement of light blocking patterns in a color converting substrate according to another embodiment of the disclosure. 
     Referring to  FIG. 24 , light blocking patterns  240 _ 1  of a color converting substrate  30 _ 1  may be disposed in a third light blocking region BA 3  between two adjacent third light transmitting regions TA 3  and in a seventh light blocking region BA 7  between two adjacent first light transmitting regions TA 1 . The color converting substrate  30 _ 1  of  FIG. 24  is the same as the color converting substrate  30  of  FIG. 14  except that the light blocking patterns  240 _ 1  are also disposed in the seventh light blocking region BA 7  and an eighth light blocking region BAB. The color converting substrate  30 _ 1  of  FIG. 24  will hereinafter be described, focusing mainly on the differences with the color converting substrate  30  of  FIG. 14 . 
     In a first row RT 1  of the color converting substrate  30 _ 1 , first light transmitting regions TA 1 , second light transmitting regions TA 2 , and the third light transmitting regions TA 3  may be arranged in the order of first, second, and third light transmitting regions TA 1 , TA 2 , and TA 3  or in the order of third, second, and first light transmitting regions TA 3 , TA 2 , and TA 1 . Two identical light transmitting regions TA, for example, the first light transmitting regions TA 1  or the third light transmitting regions TA 3 , may be disposed adjacent to each other between a first region where the first light transmitting regions TA 1 , the second light transmitting regions TA 2 , and the third light transmitting regions TA 3  are arranged in the order of first, second, and third light transmitting regions TA 1 , TA 2 , and TA 3  and a second region where the first light transmitting regions TA 1 , the second light transmitting regions TA 2 , and the third light transmitting regions TA 3  are arranged in the order of third, second, and first light transmitting regions TA 3 , TA 2 , and TA 1 . In the color converting substrate  30 _ 1 , barriers  370  and light blocking members  220  may not be provided between every two adjacent identical light transmitting regions TA, and the light blocking patterns  240 _ 1  may be disposed between every two adjacent identical light transmitting regions TA. In the color converting substrate  30 _ 1  of  FIG. 24 , unlike in the color converting substrate  30  of  FIG. 14 , the barriers  370 , seventh light blocking members  227 , and eighth light blocking members  228  are not provided in a seventh light blocking region BA 7  where two first light transmitting regions TA 1  are disposed adjacent to each other and in an eighth light blocking region BA 8  where two fourth light transmitting regions TA 4  are disposed adjacent to each other, and the light blocking patterns  240 _ 1  may be disposed in the seventh and eighth light blocking regions BA 7  and BA 8 . Accordingly, the first light transmitting regions TA 1  may have first light blocking members  221  disposed on sides thereof that are adjacent to the second light transmitting regions TA 2  and may have the light blocking patterns  240 _ 1  disposed on sides thereof that are adjacent to other first light transmitting regions TA 1 . That is, in the color converting substrate  30 _ 1  of  FIG. 24 , the first light transmitting regions TA 1  may be second-type light transmitting regions. 
     During the fabrication of the color converting substrate  30 _ 1  of  FIG. 24 , the light transmitting patterns  350  and the first wavelength converting patterns  330  can be formed in two types of light transmitting regions TA, i.e., two third light transmitting regions TA 3  and two first light transmitting regions TA 1 . Although not specifically illustrated, the first wavelength converting patterns  330 , like the light transmitting patterns  350 , may overlap with the light blocking patterns  240 _ 1  in the plan view. 
       FIG. 25  is a plan view illustrating the arrangement of a light blocking pattern in a color converting substrate according to another embodiment of the disclosure.  FIG. 26  is a cross-sectional view taken along line X 8 -X 8 ′ of  FIG. 25 . 
     Referring to  FIGS. 25 and 26 , a light blocking pattern  240 _ 2  of a color converting substrate  30 _ 2  may be disposed in ninth light blocking regions BA 9  to extend in a first direction DR 1 . The color converting substrate  30 _ 2  of  FIG. 25  is the same as the color converting substrate  30 _ 1  of  FIG. 24  except that the light blocking pattern  240 _ 2  is disposed in the ninth light blocking regions BA 9 . The color converting substrate  30 _ 2  of  FIG. 25  will hereinafter be described, focusing mainly on the differences with the color converting substrate  30 _ 1  of  FIG. 24 . 
     In the color converting substrate  30 _ 2  of  FIGS. 25 and 26 , ninth light blocking members  229  are not provided, and the light blocking pattern  240 _ 2  may be disposed in the ninth light blocking regions BA 9 . During the fabrication of the color converting substrate  30 _ 2 , the light blocking pattern  240 _ 2  may be formed by applying laser light between each pair of adjacent identical light transmitting regions, for example, between third light transmitting regions TA 3  and between first light transmitting regions TA 1 . The laser light may also be applied between first and second rows RT 1  and RT 2  of the color converting substrate  30 _ 2 , i.e., in the ninth light blocking regions BA 9 . Parts of the light blocking pattern  240 _ 2  disposed between each pair of adjacent light transmitting regions may extend in a second direction DR 2 , and parts of the light blocking pattern  240 _ 2  disposed between the first and second rows RT 1  and RT 2  may extend in the first direction DR 1 . 
     Although not specifically illustrated, first wavelength converting patterns  330 , second wavelength converting patterns  340 , and light transmitting patterns  350  may be formed as islands that are spaced apart from one another in the ninth light blocking regions BA 9 , instead of extending in the second direction DR 2 . Also, first color filters  231 , second color filters  232 , and third color filters  233  may be formed as islands. In this case, in the ninth light blocking regions BA 9  of  FIG. 26 , the first color filters  231 , the second color filters  232 , the third color filters  233 , the first wavelength converting patterns  330 , the second wavelength converting patterns  340 , and the light transmitting patterns  350  may not be disposed, and barriers  370  may be formed instead. 
       FIGS. 27 and 28  are cross-sectional views illustrating light blocking patterns according to other embodiments of the disclosure. 
     As described above, laser light for forming a light blocking pattern  240  during the fabrication of a color converting substrate  30  may not necessarily be applied from below the other surface of a second base part  310 . Also, the light blocking pattern  240  may not necessarily be formed by applying laser light, but may be formed by patterning substantially the same material as light blocking members  220 . 
     Referring to  FIG. 27 , a light blocking pattern  240 _ 4  may be disposed on one surface of a second capping layer  393 . A color converting substrate  30 _ 4  of  FIG. 27  may be disposed on the second capping layer  393  and may prevent color mixing that may occur between adjacent third light transmitting regions TA 3 . The light blocking pattern  240 _ 4  may be spaced apart from the second base part  310 . In this case, the light blocking pattern  240 _ 4  may be positioned closer to a display substrate  10 , upon which emission light L is incident, in the color converting substrate  30 _ 4  than in the color converting substrate  30  of  FIGS. 5 and 6 . 
     In one example, a thickness TH 240 _ 4  of the light blocking pattern  240 _ 4 , which is positioned on the second capping layer  393 , may be smaller than the thickness TH 240  of the light blocking pattern  240  on one surface of the second base part  310 . As the light blocking pattern  240 _ 4  is positioned close to light-emitting elements ED, light emitted from arbitrary light-emitting elements, i.e., third light-emitting elements ED 3 , can be prevented from being output to other third light transmitting regions TA 3  than their respective third light transmitting regions, even though the light blocking pattern  240 _ 4  is thinner than when positioned on one surface of the second base part  310 . 
     The light blocking pattern  240 _ 4  may include substantially the same material as the light blocking members  220  and may be formed by the same method as the light blocking members  220 . The light blocking pattern  240 _ 4  of  FIG. 27  may be formed by forming light transmitting patterns  350  and the second capping layer  393 , which covers the light transmitting patterns  350 , on one surface of the second base part  310  and coating and exposing an organic light-blocking material on the second capping layer  393 , but the disclosure is not limited thereto. 
     Referring to  FIG. 28 , a light blocking pattern  240 _ 5  may be formed to be spaced apart from a second base part  310 , but may be surrounded by light transmitting patterns  350 . That is, side surfaces of the light blocking pattern  240 _ 5  may be in contact with the light transmitting patterns  350 , but not with third color filters  233 . The side surface of the light blocking pattern  240 _ 5  is a surface parallel to the third direction DR 3  as shown in  FIG. 28 . The light blocking pattern  240 _ 5  may be formed by forming the light transmitting patterns  350  and a second capping layer  393 , which covers the light transmitting patterns  350 , on one surface of the second base part  310  and applying laser light from above the second capping layer  393  to carbonize parts of the second capping layer  393  and the light transmitting patterns  350 . The light blocking pattern  240 _ 5  of  FIG. 28 , unlike the light blocking pattern  240  of  FIGS. 5 and 6 , may be spaced apart from the second base part  310  and may thus be in contact with the second capping layer  393 , instead of being in contact with a first capping layer  391 . 
     Also, the light blocking pattern  240 _ 5  of  FIG. 28  may be positioned closer than the light blocking pattern  240  of  FIGS. 5 and 6  to a display substrate  10 , upon which emission light L is incident. 
     In one example, a thickness TH 240 _ 5  of the light blocking pattern  240 _ 5 , which is formed to be in contact with the second capping layer  393 , may be smaller than the thickness TH 240  of the light blocking pattern  240 , which is positioned on one surface of the second base part  310 . This is the same as described above with reference to  FIG. 27 , and thus, a detailed description thereof will be omitted. 
       FIGS. 29 and 30  are cross-sectional views of display devices according to other embodiments of the disclosure.  FIG. 29  is a cross-sectional view taken across first, second, and third light transmitting regions TA 1 , TA 2 , and TA 3  of a display device  1  according to another embodiment of the disclosure, and  FIG. 30  is a cross-sectional view taken across a second light transmitting region TA 2 , a third light transmitting region TA 3 , and another third light transmitting region TA 3  of the display device  1  according to another embodiment of the disclosure. 
     Referring to  FIGS. 29 and 30 , a color converting substrate  30 _ 6  may further include a plurality of color patterns ( 251 _ 6 ,  252 _ 6 , and  257 _ 6 ). The color converting substrate  30 _ 6  of  FIGS. 29 and 30  is the same as the color converting substrate  30  of  FIGS. 5 and 6  except that it further includes the color patterns ( 251 _ 6 ,  252 _ 6 , and  257 _ 6 ), which are disposed on one surface of a second base part  310 . Thus, the color converting substrate  30 _ 6  of  FIGS. 29 and 30  will hereinafter be described, focusing mainly on the differences with the color converting substrate  30  of  FIGS. 5 and 6 . 
     The color patterns ( 251 _ 6 ,  252 _ 6 , and  257 _ 6 ) can reduce the reflection of external light by absorbing some of the light introduced from outside the display device  1  to the color converting substrate  30 _ 6 . 
     In some embodiments, the color patterns ( 251 _ 6 ,  252 _ 6 , and  257 _ 6 ), like third color filters  233 , may include a blue colorant such as a blue pigment or a blue dye. In some embodiments, the color patterns ( 251 _ 6 ,  252 _ 6 , and  257 _ 6 ) may be formed of the same material as the third color filters  233  and may be formed during the formation of the third color filters  233 . That is, the third color filters  233  and the color patterns ( 251 _ 6 ,  252 _ 6 , and  257 _ 6 ) may be formed at the same time by applying a photosensitive organic material including a blue colorant on one surface of the second base part  310  and exposing and developing the photosensitive organic material. 
     In some embodiments, the thickness of the color patterns ( 251 _ 6 ,  252 _ 6 , and  257 _ 6 ) may be substantially the same as the thickness of the third color filters  233 . In a case where the color patterns ( 251 _ 6 ,  252 _ 6 , and  257 _ 6 ) include a blue colorant, external light or reflected light passing through the color patterns ( 251 _ 6 ,  252 _ 6 , and  257 _ 6 ) may have a blue wavelength range. Eye color sensibility may vary depending on the color of light. Specifically, blue-wavelength light may be perceived by a user less sensitively than green- and red-wavelength light. Thus, as the color patterns ( 251 _ 6 ,  252 _ 6 , and  257 _ 6 ) include a blue colorant, the user can perceive reflected light less sensitively. 
     Some of the color patterns ( 251 _ 6 ,  252 _ 6 , and  257 _ 6 ) may be positioned on the surface of the second base part  310  and may be located in light blocking regions BA. Also, the color patterns ( 251 _ 6 ,  252 _ 6 , and  257 _ 6 ) may be disposed to overlap with a non-emission region NLA in the plan view. In some embodiments, the color patterns ( 251 _ 6 ,  252 _ 6 , and  257 _ 6 ) may be in direct contact with the surface of the second base part  310 . Alternatively, in a case where a separate buffer layer for preventing the introduction of impurities is disposed on the surface of the second base part  310 , the color patterns ( 251 _ 6 ,  252 _ 6 , and  257 _ 6 ) may be in direct contact with the buffer layer. 
     In some embodiments, the color patterns ( 251 _ 6 ,  252 _ 6 , and  257 _ 6 ) may include first color patterns  251 _ 6 , which are positioned in first light blocking regions BA 1 , second color patterns  252 _ 6 , which are positioned in second light blocking regions BA 2 , and seventh color patterns  257 _ 6 , which are positioned in seventh light blocking regions BA 7 . Although not specifically, color patterns may also be disposed in fourth light blocking regions BA 4 , fifth light blocking regions BA 5 , eighth light blocking regions BAB, and ninth light blocking regions BA 9 . However, color patterns may be formed in third and sixth light blocking regions BA 3  and BA 6  by substantially the same process as the third color filters  233  and may form a light blocking pattern  240  via laser light. Color patterns adjacent to the third color filters  233 , i.e., the second color patterns  252 _ 6 , may be connected to the third color filters  233 . 
     As the color patterns ( 251 _ 6 ,  252 _ 6 , and  257 _ 6 ) are disposed on the surface of the second base part  310 , light blocking members  220  may be positioned on the color patterns ( 251 _ 6 ,  252 _ 6 , and  257 _ 6 ). In some embodiments, first light blocking members  221  may be positioned on the first color patterns  251 _ 6 , second light blocking members  222  may be positioned on the second color patterns  252 _ 6 , and seventh light blocking members  227 , which are positioned on the seventh color patterns  257 _ 6 . Although not specifically illustrated, color patterns may also be positioned on the fourth light blocking members  224 , the fifth light blocking members  225 , the eighth light blocking members  228 , and the ninth light blocking members  229 . In some embodiments, as the color patterns ( 251 _ 6 ,  252 _ 6 , and  257 _ 6 ) are positioned between the light blocking members  220  and the second base part  310 , the light blocking members  220  may not be in contact with the second base part  310 . 
     The color patterns ( 251 _ 6 ,  252 _ 6 , and  257 _ 6 ) can reduce the reflection of external light by absorbing some of the light introduced from outside the display device  1  to the color converting substrate  30 . 
     Meanwhile, the display device  1  may have a different layout of the emission regions LA of the display substrate  10  and the light transmitting regions TA of the color converting substrate  30  from that illustrated in  FIGS. 3 and 4 . In some embodiments, different emission regions LA and different light transmitting regions TA may be alternately arranged in the first and second directions DR 1  and DR 2 . 
       FIG. 31  is a plan view of a display substrate in a display area of a display device according to another embodiment of the disclosure.  FIG. 32  is a plan view of a color converting substrate in the display area of the display device of  FIG. 31 .  FIG. 33  is a plan view illustrating the arrangement of barriers and light blocking members in the color converting substrate of  FIG. 32 .  FIG. 34  is a plan view illustrating the arrangement of light blocking patterns in the color converting substrate of  FIG. 32 . 
     Referring to  FIGS. 31 through 34 , a display substrate  10 _ 7  may include a plurality of emission regions LA, which are arranged in multiple rows RL in a display area DA. The rows RL may include odd-numbered rows (RL 1 , RL 3 , RL 5 , . . . ) and even-numbered rows (RL 2 , RL 4 , RL 6 , . . . ) and may include different types of emission regions LA from one another. 
     In one example, in a first row RL 1  of the display substrate  10 _ 7 , third emission regions LA 3  may be repeatedly arranged, and in a second row RL 2  of the display substrate  10 _ 7 , first emission regions LA 1  and second emission regions LA 2  may be alternately arranged. The first emission regions LA 1  and the second emission regions LA 2  may be disposed to be spaced apart from one another in a first direction DR 1 , in the second row RL 2 , and the third emission region LA 3  may be disposed to be aligned in the spaces between the first emission regions LA 1  and the second emission regions LA 2  in a second direction DR 2 , in the first row RL 1 , and may thus be arranged in a staggered fashion with the first emission regions LA 1  and the second emission regions LA 2 . In the first row RL 1 , which is an odd-numbered row, the third emission regions LA 3  may be disposed, and in the second row RL 2 , which is an even-numbered row, the first emission regions LA 1  and the second emission regions LA 2  may be disposed. 
     On the contrary, in a third row RL 3 , which is an odd-numbered row, fourth emission regions LA 4  and fifth emission regions LA 5  may be alternately arranged, and in a fourth row RL 4 , which is an even-numbered row, sixth emission regions LA 6  may be repeatedly arranged. The fourth emission regions LA 4  and the fifth emission regions LA 5  may be disposed to be spaced apart from one another in the first direction DR 1 , in the third row RL 3 , and the sixth emission regions LA 6  may be disposed to be aligned in the spaces between the fourth emission regions LA 4  and the fifth emission regions LA 5  in the second direction DR 2 , in the fourth row RL 4 , and may thus be arranged in a staggered fashion with the fourth emission regions LA 4  and the fifth emission regions LA 5 . The arrangements of the emission regions LA in the first and second rows RL 1  and RL 2  may be symmetrical with the arrangements of the emission regions LA in the third and fourth rows RL 3  and RL 4 . 
     The arrangements of the emission regions LA in fifth and sixth rows RL 5  and RL 6  may be the same as the arrangements of the emission regions LA in the first and second rows RL 1  and RL 2 . That is, in the fifth rows RL 5 , third emission regions L 3  may be repeatedly arranged, and in the sixth row RL 6 , first emission regions LA 1  and second emission regions LA 2  may be alternately arranged. 
     Accordingly, the first emission regions LA 1  and the fourth emission regions LA 2  may be disposed adjacent to one another in the second direction DR 2 , and the second emission regions LA 2  and the fifth emission regions LA 5  may be disposed adjacent to one another in the second direction DR 2 . Also, the third emission regions LA 3  and the sixth emission regions LA 6  may be disposed adjacent to one another in the second direction DR 2 . The arrangement of the emission regions LA of the display substrate  10 _ 7  may correspond to the arrangement of light transmitting regions TA of a color converting substrate  30 _ 7 . In some embodiments, light transmitting regions TA that transmit light of the same color therethrough may be disposed adjacent to one another, and emission regions LA corresponding to the transmitting regions TA that transmit light of the same color therethrough may also be disposed adjacent to one another. 
     As described above, a region where the light emitting regions LA are not disposed may be defined as a non-emission region NLA. 
     The emission regions LA may have widths (WL 1 , WL 2 , and WL 3 ) in the first direction DR 1 . A first width WL 1  of the first emission regions LA 1  and a second width WL 2  of the second emission regions WL 2  are illustrated as being greater than a third width WL 3  of the third emission regions LA 3 , but the disclosure is not limited thereto. The widths and the areas of the first emission regions LA 1 , the second emission regions LA 2 , the third emission regions LA 3 , the fourth emission regions LA 4 , the fifth emission regions LA 5 , and the sixth emission regions LA 6  may vary, as necessary. 
     Similarly, the display area DA of the color converting substrate  30 _ 7  may include a plurality of light transmitting regions TA, which are disposed in multiple rows RT. The rows RT may include odd-numbered rows (RT 1 , RT 3 , RT 5 , . . . ) and even-numbered rows (RT 2 , RT 4 , RT 6 , . . . ) and may include different types of light transmitting regions TA from one another. 
     In one example, in a first row RT 1  of the color converting substrate  30 _ 7 , third light transmitting regions TA 3  may be repeatedly arranged, and in a second row RT 2  of the color converting substrate  30 _ 7 , first light transmitting regions TA 1  and second light transmitting regions TA 2  may be alternately arranged. The first light transmitting regions TA 1  and the second light transmitting regions TA 2  may be disposed to be spaced apart from one another in the first direction DR 1 , in the second row RT 2 , and the third emission region LA 3  may be disposed to be aligned in the spaces between the first light transmitting regions TA 1  and the second light transmitting regions TA 2  in the second direction DR 2 , in the first row RT 1 , and may thus be arranged in a staggered fashion with the first light transmitting regions TA 1  and the second light transmitting regions TA 2 . In the first row RT 1 , which is an odd-numbered row, the third light transmitting regions TA 3  may be disposed, and in the second row RT 2 , which is an even-numbered row, the first light transmitting regions TA 1  and the second light transmitting regions TA 2  may be disposed. 
     On the contrary, in a third row RT 3 , which is an odd-numbered row, fourth light transmitting regions TA 4  and fifth light transmitting regions TA 5  may be alternately arranged, and in a fourth row RT 4 , which is an even-numbered row, sixth light transmitting regions TA 6  may be repeatedly arranged. The fourth light transmitting regions TA 4  and the fifth light transmitting regions TA 5  may be disposed to be spaced apart from one another in the first direction DR 1 , in the third row RT 3 , and the sixth light transmitting regions TA 6  may be disposed to be aligned in the spaces between the fourth light transmitting regions TA 4  and the fifth light transmitting regions TA 5  in the second direction DR 2 , in the fourth row RT 4 , and may thus be arranged in a staggered fashion with the fourth light transmitting regions TA 4  and the fifth light transmitting regions TA 5 . The arrangements of the light transmitting regions TA in the first and second rows RT 1  and RT 2  may be symmetrical with the arrangements of the light transmitting regions TA in the third and fourth rows RT 3  and RT 4 . 
     The arrangements of the light transmitting regions TA in fifth and sixth rows RT 5  and RT 6  may be the same as the arrangements of the light transmitting regions TA in the first and second rows RT 1  and RT 2 . That is, in the fifth rows RT 5 , third light transmitting regions T 3  may be repeatedly arranged, and in the sixth row RT 6 , first light transmitting regions TA 1  and second light transmitting regions TA 2  may be alternately arranged. 
     Accordingly, the first light transmitting regions TA 1  and the fourth light transmitting regions TA 2  may be disposed adjacent to one another in the second direction DR 2 , and the second light transmitting regions TA 2  and the fifth light transmitting regions TA 5  may be disposed adjacent to one another in the second direction DR 2 . Also, the third light transmitting regions TA 3  and the sixth light transmitting regions TA 6  may be disposed adjacent to one another in the second direction DR 2 . 
     As described above, as color filters including the same colorant, for example, first color filters  231 , are disposed in the first light transmitting regions TA 1  and the fourth light transmitting regions TA 4 , the first light transmitting regions TA 1  and the fourth light transmitting regions TA 4  may transmit light of the same color therethrough. Also, as color filters including the same colorant, for example, second color filters  232 , are disposed in the second light transmitting regions TA 2  and the fifth light transmitting regions TA 5 , the second light transmitting regions TA 2  and the fifth light transmitting regions TA 5  may transmit light of the same color therethrough. Also, as color filters including the same colorant, for example, third color filters  233 , are disposed in the third light transmitting regions TA 3  and the sixth light transmitting regions TA 6 , the third light transmitting regions TA 3  and the sixth light transmitting regions TA 6  may transmit light of the same color therethrough. 
     Although not specifically illustrated, first wavelength converting patterns  330  and first color filters  231  may be disposed in the first light transmitting regions TA 1 , second wavelength converting pattern  340  and second color filters  232  may be disposed in the second light transmitting regions TA 2 , and light transmitting patterns  350  and third color filters  233  may be disposed in the third light transmitting regions TA 3 . Also, first wavelength converting patterns  330  and first color filters  231  may be disposed in the fourth light transmitting regions TA 4 , second wavelength converting pattern  340  and second color filters  232  may be disposed in the fifth light transmitting regions TA 5 , and light transmitting patterns  350  and third color filters  233  may be disposed in the sixth light transmitting regions TA 6 . Wavelength converting patterns ( 330  and  340 ) and light transmitting patterns  350  may be disposed in areas surrounded by barriers  370 _ 7 , which are disposed in the light blocking regions BA, to correspond to the light transmitting regions TA. In some embodiments, the wavelength converting patterns ( 330  and  340 ) and the light transmitting patterns  350  may be disposed on one surface of a second base part  310  to form island patterns. 
     In the color converting substrate  30 _ 7 , light transmitting regions TA where identical color filters are disposed to transmit light of the same color therethrough may be arranged adjacent to one another at least in the second direction DR 2 . The first light transmitting regions TA 1  and the second light transmitting regions TA 2 , which are alternately arranged in the second row RT 2  of the color converting substrate  30 _ 7 , may be disposed adjacent to the fourth light transmitting regions TA 4  and the fifth light transmitting regions TA 5 , respectively, which are alternately arranged in the third row RT 3  of the color converting substrate  30 _ 7 . Also, the sixth light transmitting regions TA 6 , which are repeatedly arranged in the fourth row RT 4 , may be arranged adjacent to the third light transmitting regions TA 3 , which are repeatedly arranged in the fifth row RT 5 . The emission regions LA of the display substrate  10 _ 7  of the display device  1  may be arranged to correspond to the light transmitting regions TA of the color converting substrate  30 _ 7 . 
     The light blocking regions BA may be defined in a region where the light transmitting regions TA are not disposed. The light blocking regions BA may include first light blocking regions BA 1  between the first light transmitting regions TA 1  and the second light transmitting regions TA 2  and a third light blocking region BA 3  between the third light transmitting regions TA 3 . The light blocking regions BA may further include fourth light blocking regions BA 4  between the fourth light transmitting regions TA 4  and the fifth light transmitting regions TA 5  and a sixth light blocking region BA 6  between the sixth light transmitting regions TA 6 . The light blocking regions BA may further include seventh light blocking regions BA 7 , an eighth light blocking region BA 8 , and a ninth light blocking region BA 9 , which extend in the first direction DR 1  between the rows RT. The seventh light blocking regions BA 7  may be disposed between the first and second rows RT 1  and RT 2 , the eighth light blocking region BA 8  may be disposed between the second and third rows RT 2  and RT 3 , and the ninth light blocking region BA 9  may be disposed between the fourth and fifth rows RT 4  and RT 5 . The seventh light blocking regions BA 7  may also be disposed between the third and fourth rows RT 3  and RT 4  and between the fifth and sixth rows RT 5  and RT 6 . 
     As described above, light blocking members  220 _ 7 , barriers  370 _ 7 , and light blocking patterns  240 _ 7  may be disposed in the light blocking regions BA to separate each pair of adjacent light blocking regions TA. The light blocking patterns  240  may be disposed between each pair of adjacent light transmitting regions TA that transmit light of the same color therethrough. In one example, the light blocking patterns  240  may be disposed between the first light transmitting regions TA 1  and the fourth light transmitting regions TA 4 , which are alternately arranged in the second and third rows RT 2  and RT 3 , respectively, and between the second and fifth light transmitting regions TA 2  and TA 5 , which are alternately arranged in the second and third rows RT 2  and RT 3 , respectively. The light blocking patterns  240 _ 7  may be disposed in the eighth light blocking region BA 8  to separate each pair of adjacent light transmitting regions TA from the second and third rows RT 2  and RT 3 . Also, the light blocking patterns  240 _ 7  may be disposed between the third light transmitting regions TA 3 , which are repeatedly arranged in each of the fourth and fifth rows RT 4  and RT 5 , i.e., in the ninth light blocking region BA 9 . 
     In light blocking regions BA where the light blocking patterns  240 _ 7  are not disposed, the light blocking members  220 _ 7  and the barriers  370 _ 7  may be disposed. The light blocking members  220 _ 7  and the barriers  370 _ 7  may be disposed in all the light blocking regions BA except for the eighth and ninth light blocking regions BA 8  and BA 9  to surround the light transmitting regions TA. The light blocking members  220 _ 7  and the barriers  370 _ 7  may separate each pair of adjacent light transmitting regions that transmit light of different colors or of the same color therethrough. 
     The light blocking members  220 _ 7  or the barriers  370 _ 7  may be disposed between each pair of adjacent light transmitting regions TA to define each pair of adjacent light transmitting regions TA, but the light blocking patterns  240 _ 7  may be disposed between light transmitting regions TA That transmit light of the same color therethrough. In the color converting substrate  30 _ 7 , some light transmitting regions TA that transmit light of the same color therethrough may be arranged adjacent to one another with no barriers  370 _ 7  disposed therebetween. As described above, in a case where the wavelength converting patterns ( 330  and  340 ) and the light transmitting patterns  350  are formed by inkjet printing, a necessary amount of ink needs to be sprayed at a location corresponding to each of the light transmitting regions TA. In a case where light transmitting regions TA that transmit light of the same color therethrough are disposed adjacent to one another, the impact precision of ink required for ink to be precisely mounted in each of the light transmitting regions TA can be lowered because ink can be sprayed into neighboring light transmitting regions TA at the same time. Accordingly, during the fabrication of the color converting substrate  30 _ 7  through inkjet printing, the impact precision of ink can be improved, and the distribution of inkjet printing processes using multiple nozzles can be improved. 
     Also, the light transmitting regions TA and the emission regions LA may have greater widths WL and WT in the first direction DR 1  than their respective counterparts of  FIG. 4  and may have smaller widths in the second direction DR 2  than their respective counterparts of  FIG. 4 . As the difference between the width, in the first direction DR 1 , of the light transmitting regions TA and the length, in the second direction DR 2 , of the light transmitting regions TA decreases, any loss in the light conversion efficiency of the wavelength converting patterns  330  and  340  can be minimized. 
       FIGS. 35 and 36  are plan views illustrating the arrangement of light blocking patterns in each of color converting substrates according to other embodiments of the disclosure. 
     Referring to  FIG. 35 , in a color converting substrate  30 _ 8 , light blocking patterns  240 _ 8  may be disposed only between neighboring light transmitting regions TA. In the embodiment of  FIG. 35 , unlike in the embodiment of  FIG. 34 , the light blocking patterns  240 _ 8  may be disposed only between light transmitting regions TA that transmit light of the same color therethrough. In one example, light blocking patterns  240 _ 8  may be disposed only between second and third rows RT 2  and RT 3 , particularly, between first and fourth light transmitting regions TA 1  and TA 4  and between second and fifth light transmitting regions TA 2  and TA 5 . The light blocking patterns  240 _ 8  disposed between the second and third rows RT 2  and RT 3  may be spaced apart from one another in a first direction DR 1 . In regions between the second row RT 2  and the third row RT 3  where the light blocking patterns  240 _ 8  are not disposed, light blocking members  220  and barriers  370  may be disposed. 
     In the embodiment of  FIG. 35 , like in the embodiment of  FIG. 34 , as laser light is applied along the spaces between the light transmitting regions TA during the formation of the light blocking patterns  240 _ 7 , the light blocking patterns  240 _ 7  may be formed to extend in the first direction DR 1 , but the disclosure is not limited thereto. Alternatively, the laser light may be applied only into the spaces between neighboring light transmitting regions TA so that the light blocking patterns  240 _ 8  may be spaced apart from one another in the first direction DR 1 . The light blocking patterns  240 _ 8  may be formed as island patterns, over the entire surface of the color converting substrate  30 _ 8 . The embodiment of  FIG. 35  differs from the embodiment of  FIG. 34  in the arrangement of the light blocking patterns  240 _ 8 . 
     Also, some of the light transmitting regions TA arranged in the same row may be identical light transmitting regions TA disposed adjacent to one another. 
     Referring to  FIG. 36 , some of light transmitting regions TA of a color converting substrate  30 _ 9  may be identical light transmitting regions TA disposed adjacent to one another in a first direction DR 1 . In one example, first light transmitting regions TA 1  and second light transmitting regions TA 2  may be alternately arranged in a second row RT 2 , but the first light transmitting regions TA 1  or the second light transmitting regions TA 2  may be disposed adjacent to one another. Light blocking patterns  240 _ 9  may be disposed even between each pair of adjacent first light transmitting regions TA 1  and between each pair of adjacent second light transmitting regions TA 2 . That is, the light blocking patterns  240 _ 9  may be disposed not only in eighth and ninth light blocking regions BA 8  and BA 9 , but also in a second light blocking region BA 2 . In this case, barriers  370  and light blocking members  220  are not disposed between second light transmitting regions TA 2  and fifth light transmitting regions TA 5 , which are disposed adjacent to the second light transmitting regions TA 2 , and the second light transmitting regions TA 2  and the fifth light transmitting regions TA 5  may be separated from one another by the gaps therebetween. The embodiment of  FIG. 36  differs from the embodiment of  FIG. 34  in the arrangements of the light transmitting regions TA and the light blocking patterns  240 _ 9 . 
     In the color converting substrate  30 _ 9 , different light transmitting regions TA that transmit light of the same color therethrough or identical light transmitting regions that transmit light of the same color therethrough may be disposed adjacent to one another, and the light blocking patterns  240 _ 9  may be disposed between the different light transmitting regions TA or the identical light transmitting regions TA. Accordingly, even if the area of the light transmitting regions TA decreases, the impact precision of ink required for inkjet printing can be lowered, and the distribution of processes can be improved. 
     In concluding the detailed description, those skilled in the art will appreciate that many variations and modifications can be made to the preferred embodiments without substantially departing from the principles of the invention. Therefore, the disclosed preferred embodiments of the invention are used in a generic and descriptive sense only and not for purposes of limitation.
