     DETAILED DESCRIPTION 
     The present disclosure may be understood by reference to the following detailed description, taken in conjunction with the drawings as described below. It is noted that, for purposes of illustrative clarity and being easily understood by the readers, various drawings of this disclosure show a portion of an electronic device in this disclosure, and certain elements in various drawings may not be drawn to scale. In addition, the number and dimension of each device shown in drawings are only illustrative and are not intended to limit the scope of the present disclosure. 
     Certain terms are used throughout the description and following claims to refer to particular components. As one skilled in the art will understand, electronic equipment manufacturers may refer to a component by different names. This document does not intend to distinguish between components that differ in name but not function. In the following description and in the claims, the terms “include”, “comprise” and “have” are used in an open-ended fashion, and thus should be interpreted to mean “include, but not limited to . . . ”. Thus, when the terms “include”, “comprise” and/or “have” are used in the description of the present disclosure, the corresponding features, areas, steps, operations and/or components would be pointed to existence, but not limited to the existence of one or a plurality of the corresponding features, areas, steps, operations and/or components. 
     The directional terms used throughout the description and following claims, such as: “on”, “up”, “above”, “down”, “under”, “below”, “underneath”, “front”, “rear”, “back”, “left”, “right”, etc., are only directions referring to the drawings. Therefore, the directional terms are used for explaining and not used for limiting the present disclosure. Regarding the drawings, the drawings show the general characteristics of methods, structures, and/or materials used in specific embodiments. However, the drawings should not be construed as defining or limiting the scope or properties encompassed by these embodiments. For example, for clarity, the relative size, thickness, and position of each layer, each area, and/or each structure may be reduced or enlarged. 
     When the corresponding component such as layer or area is referred to “on another component”, it may be directly on this another component, or other component (s) may exist between them. On the other hand, when the component is referred to “directly on another component (or the variant thereof)”, any component does not exist between them. Furthermore, when the corresponding component is referred to “on another component”, the corresponding component and the another component have a disposition relationship along a top-view direction, the corresponding component may be below or above the another component, and the disposition relationship along the top-view direction are determined by an orientation of the device. 
     It will be understood that when a component or layer is referred to as being “connected to” another component or layer, it can be directly connected to this another component or layer, or intervening components or layers may be presented. When a component is referred to as being “directly connected to” another component or layer, there are no intervening components or layers presented. In addition, when the component is referred to “be coupled to/with another component (or the variant thereof)”, it may be directly connected to this another component, or may be indirectly connected (such as electrically connected) to this another component through other component(s). 
     The terms “about”, “substantially”, “equal”, or “same” generally mean within 20% of a given value or range, or mean within 10%, 5%, 3%, 2%, 1%, or 0.5% of a given value or range. 
     Although terms such as first, second, third, etc., may be used to describe diverse constituent elements, such constituent elements are not limited by the terms. These terms are used only to discriminate a constituent element from other constituent elements in the specification, and these terms have no relation to the manufacturing order of these constituent components. The claims may not use the same terms, but instead may use the terms first, second, third, etc. with respect to the order in which an element is claimed. Accordingly, in the following description, a first constituent element may be a second constituent element in a claim. 
     It should be noted that the technical features in different embodiments described in the following can be replaced, recombined, or mixed with one another to constitute another embodiment without departing from the spirit of the present disclosure.

In some embodiments, the adjacent second electrodes  158  may be electrically connected to each other through the second connecting portion  158   b.  In some embodiments, the first connecting portion  156   b  and the second connecting portion  158   b  may at least partially overlap in the top-view direction Dt, but the first connecting portion  156   b  and the second connecting portion  158   b  are insulated from each other.

As shown in  FIG.  1    and  FIG.  4   , in the region where the second electrode  158  is adjacent to the first electrode  156  (e.g., the region R of  FIG.  1   ), the second electrode  158  may partially surround the sub-pixel (e.g., the sub-pixel SPX 3 ), such that a distance S exists between the second electrode  158  and the first electrode  156  in the top-view direction Dt, the distance S may be defined by a minimum distance between the second electrode  158  and the first electrode  156  in the top-view direction Dt. For instance, the distance S is configured to separate the second electrode  158  from the first electrode  156 , the second electrode  158  is insulated from the first electrode  156 . In some embodiments, in another region where the first electrode  156  is adjacent to the second electrode  158  (not pointed out in  FIG.  1   ), the first electrode  156  partially surrounds the sub-pixel, the distance S exists between the second electrode  158  and the first electrode  156 . In some embodiments (as shown in  FIG.  4   ), the distance S may be greater than or equal to a width W 1  of the first electrode  156  (e.g., a width of the first touch layer  152  in the first electrode  156 ) and/or a width W 2  of the second electrode  158  (e.g., a width of the first touch layer  152  in the second electrode  158 ). The aforementioned width W 1  and the aforementioned width W 2  may be measured by using an optical microscopy (OM) or a scanning electron microscope (SEM) to capture the local region. For instance, under the condition that the measure is performed by using the optical microscopy, the aforementioned width W 1  and the aforementioned width W 2  may be a greatest width of the first touch layer  152  measured in the captured local region image, the greatest width (referred to the width W 1  and/or the width W 2  in  FIG.  4   ) is perpendicular to an extending direction of the first touch layer  152  in the first electrode  156  (or the second electrode  158 ). For instance, under the condition that the measure is performed by using the scanning electron microscope, the aforementioned width W 1  and the aforementioned width W 2  may be obtained by measuring a greatest width of the first touch layer  152  in the first electrode  156  (or the second electrode  158 ) in the captured SEM image showing the local region (i.e., the greatest width may be referred to the width W 1  of the first touch layer  152  in  FIG.  2   ), wherein the cutting line of this SEM image may be perpendicular to the extending direction of the first touch layer  152  in the first electrode  156  (or the second electrode  158 ), but not limited thereto. 
     In some embodiments, the electronic device  100  may optionally include other required layer(s) and/or structure(s). In some embodiments (as shown in  FIG.  2   ), the electronic device  100  may include a pixel defining layer PDL configured to separate the light emitting structures LS corresponding to different sub-pixels, but not limited thereto. In some embodiments, as shown in  FIG.  2   , the electronic device  100  may include a protecting layer PL 1 . For example, the protecting layer PL 1  is disposed between the light emitting structure LS and the light conversion structure  132   a,  the light conversion structure  132   b  and/or the light conversion structures  132   c,  so as to protect the light emitting structure LS and the light conversion structure(s), thereby reducing the influence upon the light emitting structure LS caused by moisture, oxygen and/or other substances. In some embodiments (as shown in  FIG.  2   ), the protecting layer PL 1  may have a flatting function. In some embodiments, the protecting layer PL 1  may include a single-layer structure or a multi-layer structure. For example, the protecting layer PL 1  may include an inorganic insulating layer, an organic insulating layer or a combination thereof. In some embodiments (as shown in  FIG.  2   ), for instance, the touch structure TS may be disposed on or formed on the protecting layer PL 1 . In some embodiments (as shown in  FIG.  2   ), in the cross-sectional view, the touch structure TS may have different widths. In some embodiments (as shown in  FIG.  2   ), in the cross-sectional view, the width of one side of the touch structure TS adjacent to the protecting layer PL 1  may be greater than or equal to the width of another side of the touch structure TS further from the protecting layer PL 1 , but not limited thereto. In some embodiments (not shown in figures), the width of one side of the touch structure TS adjacent to the protecting layer PL 1  may be less than or equal to the width of another side of the touch structure TS further from the protecting layer PL 1 . 
     In some embodiments, in order to decrease the influence and/or damage on the light conversion structures (e.g.,  132   a,    132   b  and/or  132   c ) during the manufacturing process, in the manufacture of the electronic device, the touch structure TS may be disposed before the light conversion structure(s) (e.g.,  132   a,    132   b  and/or  132   c ) may be disposed, but not limited thereto. In some embodiments, the light conversion structure may be protected by suitable method, the touch structure TS may be formed after forming the light conversion structure(s) (e.g.,  132   a,    132   b  and/or  132   c ). 
     The electronic device of the present disclosure is not limited to the above embodiment(s). Further embodiments of the present disclosure are described below. For ease of comparison, same components will be labeled with the same symbol in the following. The following descriptions relate the differences between each of the embodiments, and repeated parts will not be redundantly described. 
     Referring to  FIG.  5   ,  FIG.  5    is a schematic diagram showing a cross-sectional view of an electronic device according to a second embodiment of the present disclosure. As shown in  FIG.  5   , a difference between this embodiment and the first embodiment (shown in  FIG.  2   ) is that the touch structure TS of the electronic device  100   a  may include a first touch layer  152  and a second touch layer  154 , the touch structure TS may further include a light blocking layer  144 . In detail, the first touch layer  152 , the light blocking layer  142 , the second touch layer  154  and the light blocking layer  144  may be disposed on the protecting layer PL 1  in sequence, but not limited thereto. In some embodiments (in  FIG.  5   ), in the top-view direction Dt, the first touch layer  152  may be covered by the light blocking layer  142 , the second touch layer  154  may be partially covered by the light blocking layer  144 , but not limited thereto. Namely, in the top-view direction Dt, a portion of the second touch layer  154  may not overlap the light blocking layer  144 , but not limited thereto. In some embodiments (not shown in figures), in the top-view direction Dt, the second touch layer  154  may be covered by the light blocking layer  144 . When the touch layer (e.g., the second touch layer  154  or the first touch layer  152 ) is covered or coated by the light blocking layer  144  and/or the light blocking layer  142 , the effect that the touch layer is protected by the light blocking layer is enhanced, such as the unsuitable short circuit between the touch layer and other circuit component is decreased, or the disadvantaged influence on the touch layer caused by moisture and/or oxygen is reduced. In some embodiments (as shown in  FIG.  5   ), the first touch layer  152  may be underneath the light blocking layer  142  with respect to the light emitting structure LS (i.e., based on the position of the light emitting structure LS), and the second touch layer  154  may be underneath the light blocking layer  144  with respect to the light emitting structure LS, but not limited thereto. In some embodiments (as shown in  FIG.  5   ), the light blocking layer  142  may be underneath the second touch layer  154  with respect to the light emitting structure LS (i.e., based on the position of the light emitting structure LS). In some embodiments, the second touch layer  154  may be sandwiched in the light blocking layer or sandwiched between the light blocking layer  142  and the light blocking layer  144 , but not limited thereto. The arrangement of the touch layers (the first touch layer  152  and the second touch layer  154 ) and the light blocking layers ( 142  and  144 ) may be designed based on requirement(s). Other possible examples will be described in subsequent embodiments and drawings. In some embodiments (as shown in  FIG.  5   ), the material of the light blocking layer  142  and the material of the light blocking layer  144  may be the same or different; the material of the light blocking layer  142  and/or the material of the light blocking layer  144  includes insulating material. In some embodiments (as shown in  FIG.  5   ), the material of the first touch layer  152  and the material of the second touch layer  154  may be the same or different. 
     In some embodiments (as shown in  FIG.  5   ), the thickness T of the touch structure TS may be in a range from 3 μm to 35 μm (3 μm≤the thickness T≤35 μm), but not limited thereto. For example, the thickness T of the touch structure TS may be in a range from 3 μm to 17.5 μm (3 μm≤the thickness T≤17.5 μm) or in a range from 18 μm to 35 μm (18 μm≤the thickness T≤35 μm), but not limited thereto. The thickness T of the touch structure TS may be defined by a maximum thickness of the touch structure TS along the top-view direction Dt in the cross-sectional view. For instance (as shown in  FIG.  5   ), the thickness T is a maximum thickness between a surface of the touch structure TS adjacent to the cover layer  160  (e.g., a surface of the light blocking layer  144  to adjacent the cover layer  160 ) and a surface of the touch structure TS adjacent to the first substrate  110  (e.g., a surface of the light blocking layer  142  adjacent to the first substrate  110 ). In some embodiments, the thickness T 1  of the first touch layer  152  and/or the thickness T 2  of the second touch layer  154  may be in a range from about 0.1 μm to about 0.2 μm (0.1 μm≤the thickness T 1  or the thickness T 2 ≤0.2 μm). The thickness T 1  may be defined by a minimum thickness of the first touch layer  152  along the top-view direction Dt in the cross-sectional view, and the thickness T 2  may be defined by a minimum thickness of the second touch layer  154  along the top-view direction Dt in the cross-sectional view. For example, the aforementioned thickness T 1  or the aforementioned thickness T 2  may be a minimum thickness of the corresponding structure measured in an image of a local region of the corresponding structure captured by the scanning electron microscope (as shown in  FIG.  5   ), but not limited thereto. In some embodiments, the width W 3  of the touch structure TS may be in a range from about 1.5 μm to about 12 μm (1.5 μm≤the width W 3 ≤12 μm), but not limited thereto. In some embodiments, the width W 3  of the touch structure TS may be in a range from 1.5 μm to 6 μm (1.5 μm≤the width≤6 μm) or from 6 μm to 12 μm (6 μm≤the width W 3 ≤12 μm). The width W 3  of the touch structure TS may be defined by a maximum width of the touch structure TS in the cross-sectional view. The aforementioned width W 3  of the touch structure TS may be measured by the optical microscopy (OM) or the scanning electron microscope (SEM), but not limited thereto. In some embodiments (as shown in  FIG.  5   ), the side edge of the light blocking layer  142  may be approximately aligned with the side edge of the second touch layer  154 , but not limited thereto. 
     Note that, the touch layer (e.g., the first touch layer  152  and/or the second touch layer  154 ) and the light blocking layer (e.g., the light blocking layer  142  and/or the light blocking layer  144 ) are combined to be the touch structure TS according to the design of the present disclosure, so as to reduce the thickness of the electronic device  100  or the distance between the light emitting structure LS and the light conversion structure(s) (e.g.,  132   a,    132   b  and/or  132   c ), and/or decrease the distance between the light emitting structure LS and the light-emitting surface, thereby enhancing the intensity of the light, but not limited thereto. In some embodiments, the electronic device  100  (or  100   a ) may be a flexible electronic device, the thickness of the electronic device  100  (or  100   a ) may be decreased according to the aforementioned design. Thus, the flexible electronic device  100  (or  100   a ) may be bent advantageously. 
     Referring to  FIG.  6   ,  FIG.  6    is a schematic diagram showing a cross-sectional view of an electronic device according to a third embodiment of the present disclosure. As shown in  FIG.  6   , a difference between this embodiment and the first embodiment is that the touch structure TS of the electronic device  200  may be disposed between the light emitting structure LS and the light conversion structure(s) (e.g.,  132   a,    132   b  and/or  132   c ). In detail, in  FIG.  6   , the touch structure TS may include a first touch layer  152  and a second touch layer  154 , and a portion of an insulating layer IN 4  is disposed between the first touch layer  152  and the second touch layer  154  to separate the first touch layer  152  from the second touch layer  154 . The first touch layer  152  and the second touch layer  154  are formed to be a capacitor for sensing. Moreover, the electronic device  200  may include an insulating layer IN 3  disposed between the first touch layer  152  and the light emitting structure LS, and the insulating layer IN 3  may have a flatting function to facilitate the disposition of the touch structure TS, such that a difference between these capacitors (including the touch structure TS) may be decreased. In some embodiments (as shown in  FIG.  6   ), the touch structure TS is underneath a light blocking structure  140  with respect to the light emitting structure LS (i.e., based on the position of the light emitting structure LS), and the touch structure TS does not include the aforementioned light blocking layer. In some embodiments (as shown in  FIG.  6   ), in the top-view direction Dt, the touch structure TS (including the first touch layer  152  and/or the second touch layer  154 ) may be overlapped with the light blocking structure  140 . In some embodiments (as shown in  FIG.  6   ), in the top-view direction Dt, the touch structure TS (the first touch layer  152  and/or the second touch layer  154 ) may not be overlapped with the light conversion structure (e.g.,  132   a,    132   b  and/or  132   c ) and/or the light emitting structure LS. In some embodiments (as shown in  FIG.  6   ), in the top-view direction Dt, the touch structure TS is disposed between two adjacent light conversion structures (e.g.,  132   a,    132   b  and/or  132   c ). In some embodiments, the insulating layer IN 4  may include an inorganic insulating layer, an organic insulating layer or a combination thereof. 
     In some embodiments (as shown in  FIG.  6   ), the first touch layer  152  may serve as an auxiliary electrode of the light emitting structure LS. In detail, in  FIG.  6   , the first touch layer  152  may be electrically connected to the light emitting structure LS (e.g., the second electrode E 2 ) through a connecting element CP. In some embodiments (as shown in  FIG.  6   ), the insulating layer IN 3  may have a via (not shown in figures) exposing at least a portion of a surface of the light emitting structure LS (e.g., the second electrode E 2 ), and/or conductive material may be disposed in or filled in this via to form the connecting element CP, but not limited thereto. In some embodiments, the material of the connecting element CP may include any suitable conductive material, and the material of the connecting element CP may be the same as or different from the first touch layer  152 . In some embodiments (not shown), the first touch layer  152  of the electronic device  200  may be disposed on the second electrode E 2  of the light emitting structure LS and be in contact with the second electrode E 2 , so as to serve as the auxiliary electrode of the light emitting structure LS. In some embodiments, the material of the first touch layer  152  may include metal material to decrease the resistance and/or increase the transmission effect of the signal transmitting to the light emitting structure LS (e.g., the second electrode E 2 ). For instance, the signal may be evenly transmitted to the light emitting structure LS. In some embodiments, the first touch layer  152  may not be electrically connected to the light emitting structure LS (e.g., the second electrode E 2 ), the first touch layer  152  may not serve as the auxiliary electrode, and another auxiliary electrode (not shown in figures) may be optionally included in the electronic device. 
     In some embodiments, the electronic device may be a touch display device, the touch sensing function and a display function may be respectively performed in different time segments. In the touch sensing time segment, the first touch layer  152  and/or the second touch layer  154  may be configured to receive the touch signal(s), the touch signal(s) may be transmitted to the operational circuit (not shown in figures) through the trace(s) (not shown in figures) connected to the first touch layer  152  and/or the second touch layer  154 . In the display time segment, when the first touch layer  152  serves as the auxiliary electrode, a voltage source may transmit a voltage to the second electrode E 2  through the first touch layer  152 , but not limited thereto. The voltage may include common voltage (Vcom) or other suitable voltage. In some embodiments (not shown in figures), the touch structure TS of the electronic device  200  may sense the touch by using a self-capacitance sensing method. Therefore, the touch structure TS may include only one touch layer (e.g., one of the aforementioned first touch layer  152  and the aforementioned second touch layer  154 ). 
     Referring to  FIG.  7   ,  FIG.  7    is a schematic diagram showing a cross-sectional view of an electronic device according to a fourth embodiment of the present disclosure. As shown in  FIG.  7   , a difference between this embodiment and the first embodiment is that the electronic device  300  of this embodiment includes a second substrate  310  opposite to the first substrate  110 . A first substrate structure  1105  is disposed on the first substrate  110 , the first substrate structure  110 S is defined by a combination containing the layers (and/or structures) disposed on or formed on the first substrate  110 . A second substrate structure  310 S is disposed on the second substrate  310 , the second substrate structure  310 S is defined by a combination containing the layers (and/or structures) disposed on or formed on the second substrate  310 . In some embodiments (as shown in  FIG.  7   ), the first substrate structure  1105  and the second substrate structure  310 S may be adhered to each other by an adhesive layer AL. In some embodiments (as shown in  FIG.  7   ), the first substrate structure  1105  may include the circuit component layer  120  and/or the light emitting structure LS, the second substrate structure  310 S may include the light conversion structures (e.g.,  132   a,    132   b  and/or  132   c ) and/or the touch structure TS, but not limited thereto. In some embodiments, the second substrate structure  310 S may further include a protecting layer PL 2  disposed between the adhesive layer AL and the light conversion structure(s) (e.g.,  132   a,    132   b  and/or  132   c ) to protect the light conversion structure(s) (e.g.,  132   a,    132   b  and/or  132   c ), the touch structure TS and/or the light blocking layer(s) ( 144  and/or  142 ). Note that the layers (or structures) in the first substrate structure  110 S and/or the layers (or structures) in the second substrate structure  310 S may be adjusted based on requirement(s). For instance, a portion of the layers (or structures) may be removed optionally or other additional layer(s) (or structure(s)) may be added. Moreover, the material of the second substrate  310  may be the same as or different from the first substrate  110 , and this will not be redundantly described. 
     Referring to  FIG.  7   , in some embodiments, in the cross-sectional view, the touch structure TS may have different widths. In other words, a width of one side of the touch structure TS adjacent to the second substrate  310  may be greater than or equal to a width of another side of the touch structure TS further from the second substrate  310 . In some embodiments, the second touch layer  154  of the touch structure TS may be sandwiched between the light blocking layer  142  and the light blocking layer  144 . In some embodiments, in the cross-sectional view, the cross-sectional shape of the first touch layer  152  and/or the cross-sectional shape of the second touch layer  154  may be U-type shape or other suitable shape. In some embodiments, in the cross-sectional view, the cross-sectional shape of the first touch layer  152  and the cross-sectional shape of the second touch layer  154  may be the same or different. In some embodiments, an area of the second touch layer  154  projected to the second substrate  310  may be less than an area of the first touch layer  152  projected to the second substrate  310 , but not limited thereto. In some embodiments, the second touch layer  154  may not be in contact with the light conversion structure (e.g.,  132   a,    132   b  and/or  132   c ). In some embodiments (not shown in figures), the first touch layer  152  may not be in contact with the light conversion structure (e.g.,  132   a,    132   b  and/or  132   c ). 
     In some embodiments (as shown in  FIG.  7   ), in the top-view direction Dt, a portion of the first touch layer  152  and/or a portion of the second touch layer  154  may not be covered by the light blocking layer  142  and/or the light blocking layer  144 . In order to decrease ambient light reflected by the first touch layer  152  and/or the second touch layer  154  in the touch structure TS, a polarizer  320  or an anti-reflective layer (not shown in figures) may be disposed on the second substrate  310  or the touch structure TS, but not limited thereto. In some embodiments (not shown), the first touch layer  152  may be electrically connected to the light emitting structure LS (e.g., the second electrode E 2 ) of the first substrate structure  110 S through a connecting element to serve as an auxiliary electrode of the light emitting structure LS. 
     In some embodiments, the touch structure TS may be included in the second substrate structure  310 S. For instance, the first touch layer  152  may be disposed between the protecting layer PL 2  and the light blocking layer  142 , and the second touch layer  154  is disposed between the light blocking layer  142  and the second substrate  310 , but not limited thereto.

In some embodiments (as shown in  FIG.  8   ), the light blocking layer  142  may be underneath the first touch layer  152  with respect to the light emitting structure LS, but not limited thereto. In some embodiments (as shown in  FIG.  8   ), in the top-view direction Dt, the upper side of the touch structure TS is not covered by the light blocking layer  142 , in order to decrease the ambient light reflected by the touch structure TS, a polarizer  320  or a an anti-reflective layer (not shown) may be disposed on the second substrate  310  or the touch structure TS. 
     Referring to  FIG.  9   ,  FIG.  9    is a schematic diagram showing a cross-sectional view of an electronic device according to a sixth embodiment of the present disclosure. As shown in  FIG.  9   , a difference between this embodiment and the first embodiment is the disposition of the touch structure TS of the electronic device  500 . In  FIG.  9   , the first touch layer  152  of the touch structure TS may be disposed between the light emitting structure LS and the protecting layer PL 1 , the second touch layer  154  may be disposed between the light blocking layer  142  and the cover layer  160 , the light blocking layer  142  and/or the protecting layer PL 1  may be disposed between the first touch layer  152  and the second touch layer  154 , but not limited thereto.

In some embodiments (as shown in  FIG.  9   ), the touch structure TS may include the first touch layer  152 , the second touch layer  154 , the light blocking layer  142  and/or a portion of the protecting layer PL 1 , and the touch structure TS may be between two adjacent light conversion structures (e.g.,  132   a,    132   b  and/or  132   c ) in the top-view direction Dt. 
     Referring to  FIG.  10   ,  FIG.  10    is a schematic diagram showing a cross-sectional view of an electronic device according to a seventh embodiment of the present disclosure. As shown in  FIG.  10   , a difference between this embodiment and the first embodiment is that the electronic device  600  of this embodiment emits the light downwardly. That is to say, an outer surface  110   a  of the first substrate  110  is the light-emitting surface of the electronic device  600  (i.e., a surface which the user views the display image), the outer surface  110   a  of the first substrate  110  may be a surface for touch, but not limited thereto. In some embodiments (as shown in  FIG.  10   ), the light blocking layer  142 , the light blocking layer  144  and/or the light conversion structures (e.g.,  132   a,    132   b  and/or  132   c ) may be included in the first substrate structure  110 S, but not limited thereto. In some embodiments, the light blocking layer  142 , the light blocking layer  144  and/or the light conversion structures (e.g.,  132   a,    132   b  and/or  132   c ) may be disposed between the first substrate  110  and the circuit component layer  120  (or the light emitting structure LS). In some embodiments (as shown in  FIG.  10   ), the electronic device  600  may emit the light downwardly, the electronic component (s) (e.g., the switching component SW, a data line (not shown in figures) and/or a scanning line (not shown in figures), but not limited thereto) may not overlap the light emitting structure LS in the top-view direction Dt, thereby enhancing the intensity of the light or enhancing the viewing quality of the display image. In some embodiments (as shown in  FIG.  10   ), the electronic component(s) may overlap the light blocking layer  142  and/or the light blocking layer  144  in the top-view direction Dt, thereby decreasing the probability that the ambient light is reflected by the electronic component(s).
