     The present disclosure relates to a display device and an electronic apparatus. 
     BACKGROUND ART 
     In display devices, various techniques for improving light extraction efficiency have been developed for the purpose of increasing brightness. For example, a display device in which light from a plurality of light emitting elements formed on a thin film transistor (TFT) substrate is emitted via an opposite substrate arranged on a side opposite to the TFT substrate, and a layer having a recursive reflection structure is formed between the TFT substrate and the light emitting element for each pixel is disclosed in Patent Literature 1. According to the display device disclosed in Patent Literature 1, light emitted from the light emitting element toward the TFT substrate side is reflected toward the opposite substrate side by the recursive reflection structure, and thus it is possible to improve the light extraction efficiency and realize high luminance.

     DISCLOSURE OF INVENTION 
     Technical Problem 
     Here, in the display device, there is also a demand to control a viewing angle, that is, a direction of an emitted light beam for each pixel while realizing high luminance. In the technique described in Patent Literature 1, such viewing angle control is not particularly mentioned. In view of the above circumstances, there has been a demand for a technique for improving light extraction efficiency while realizing a desired viewing angle characteristic for each pixel. 
     In this regard, the present disclosure proposes a display device and an electronic apparatus which are novel and improved and capable of improving light extraction efficiency while realizing a desired viewing angle characteristic for each pixel. 
     Solution to Problem 
     According to the present disclosure, there is provided a display device, including: a plurality of light emitting sections formed on a substrate; and reflectors provided above the light emitting sections with respect to the plurality of light emitting sections positioned in at least a partial region of a display surface, lower surfaces of the reflectors reflecting part of emission light from the light emitting sections. The light emitting sections and the reflectors are arranged in a state in which centers of the reflectors are shifted from centers of luminescence surfaces of the light emitting sections in a plane perpendicular to a stacking direction so that light emitted in a direction other than a desired direction among the emission light from the light emitting sections is reflected. 
     In addition, according to the present disclosure, there is provided an electronic apparatus, including: a display device configured to perform display on a basis of an image signal. The display device includes a plurality of light emitting sections formed on a substrate, and reflectors provided above the light emitting sections with respect to the plurality of light emitting sections positioned in at least a partial region of a display surface, lower surfaces of the reflectors reflecting part of emission light from the light emitting sections, and the light emitting sections and the reflectors are arranged in a state in which centers of the reflectors are shifted from centers of luminescence surfaces of the light emitting sections in a plane perpendicular to a stacking direction so that light emitted in a direction other than a desired direction among the emission light from the light emitting sections is reflected. 
     According to the present disclosure, for each light emitting section (for example, a light emitting element in the case of an organic EL display) (that is, for each pixel), the reflector is installed above the light emitting section to reflect light emitted in a direction other than a desired direction among the emission light from the light emitting section. Therefore, in the pixel including the light emitting section, only the light from the region in which the reflector is not installed is emitted, that is, light is emitted only in a desired direction. Therefore, it is possible to realize a desired viewing angle characteristic for each pixel. Further, the light reflected by the reflector among the emission light from the light emitting section is reflected again by the luminescence surface of the light emitting section (or the interface between lower layers) and finally emitted from the region in which the reflector is not installed. Therefore, it is possible to suppress a decrease in the light extraction efficiency. As described above, according to the present disclosure, it is possible to improve light extraction efficiency while realizing a desired viewing angle characteristic for each pixel. 
     Advantageous Effects of Invention 
     As described above, according to the present disclosure, it is possible to improve light extraction efficiency while realizing a desired viewing angle characteristic for each pixel. Note that the effects described above are not necessarily limitative. With or in the place of the above effects, there may be achieved any one of the effects described in this specification or other effects that may be grasped from this specification.

     8. Supplement 
     Further, hereinafter, an embodiment in which a display device is organic electro-luminescence (EL) display (OELD) will be described as an example of the present disclosure. However, the present disclosure is not limited to this example, and the display device that is an object of the present disclosure may be various display devices as long as they are display devices that can achieve color display using color filters (CFs), such as a liquid crystal display, a plasma display, and an electronic paper device. 
     1. First Embodiment 
     1-1. Configuration of Display Device 
     The configuration of a display device according to a first embodiment of the present disclosure will now be described with reference to  FIG.  1   .  FIG.  1    is a cross-sectional view showing a configuration example of a display device according to the first embodiment.  FIG.  1    shows a schematic partial cross-sectional view of a display device according to the first embodiment. 
     Referring to  FIG.  1   , a display device  1   a  according to the first embodiment mainly includes a first substrate  101 , a plurality of light emitting elements  103  each of which includes an OLED formed on the first substrate  101  and emits white light, and a CF layer  113  in which CFs of some colors are formed to correspond to the light emitting elements  103  on the light emitting elements  103 . Further, a second substrate  117  containing a material transparent to the light from the light emitting element  103  is placed on the CF layer  113 . Although not shown, on the first substrate  11 , thin film transistors (TFTs) for driving the light emitting elements  103  are provided to correspond to the light emitting elements  103 . An arbitrary light emitting element  103  is selectively driven by the TFT, then light from the driven light emitting element  103  passes through the corresponding CF, and the color of the light is converted appropriately and the converted light is emitted from the upper side via the second substrate  117 ; thereby, desired images, characters, etc. are displayed. 
     Note that, in the following description, the stacking direction of the layers in the display device  1   a  is referred to also as an up and down direction. In this event, the side on which the first substrate  101  is placed is defined as an up side, and the side on which the second substrate  117  is placed is defined as a down side. Further, a plane perpendicular to the up and down direction is referred to also as a horizontal plane. 
     Thus, the display device  1   a  shown in  FIG.  1    is a top emission display device capable of color display that is driven by an active matrix system. However, the first embodiment is not limited to this example, and the display device according to the first embodiment may be a display device that is driven by another system such as a passive matrix system, or may be a bottom emission display device that emits light via the first substrate  101 . 
     Note that the display device  1   a  may be mounted on various electronic apparatuses having a display function. Specifically, the display device  1   a  may be used as, for example, a monitor device that is incorporated in a television device, an electronic book, a smartphone, a personal digital assistant (PDA), a notebook personal computer (PC), a video camera, a game apparatus, or the like. Alternatively, the display device  1   a  may be used for an EVF of a digital camera, an HMD, or the like. 
     As illustrated in  FIG.  1   , in further detail, a display device  1   a  is configured such that a light emitting element  103 , a first member  107 , a protection film  109 , a planarizing film  111 , and a CF layer  113  are stacked on a first substrate  101  in the described order. As described above, the display device  1   a  is a display device of a so-called on-chip color filter (OCCF) scheme in which the CF layer  113  is formed over the first substrate  101  on which the light emitting element  103  is formed. In this configuration, a second substrate  117  is bonded to the CF layer  113  of the uppermost layer with a sealing resin film  115  interposed therebetween, so that the display device  1   a  is manufactured. 
     Further, on the first substrate  101 , a pixel defining film  105  defining a pixel region is formed between the adjacent light emitting elements  103 . The pixel defining film  105  is formed to have an opening exposing the light emitting element  103  in a portion corresponding to the light emitting element  103 . The surface exposed in the opening of the light emitting element  103  corresponds to a luminescence surface of the light emitting element  103 . Further, the first member  107  is stacked to bury the opening of the pixel defining film  105 . In other words, emission light from the light emitting element  103  passes through the first member  107 , the protection film  109 , the planarizing film  111 , the CF layer  113 , the sealing resin film  115 , and the second substrate  117  and is emitted toward the outside. 
     The CF layer  113  is formed so that a CF of each color having a predetermined area is positioned above each light emitting element  103 . In the illustrated example, the CF layer  113  is provided such that a red CF  113 R, a green CF  113 G, and a blue CF  113 B each having a prescribed area are continuously distributed in an in-plane direction. Note that, in the following description, in a case where there is no need to particularly distinguish the CF  113 R, the CF  113 G, and the CF  113 B, one or a plurality of these may be written as simply a CF  113   a.    
     One pixel is formed by a combination of one light emitting element  103  and one CF  113   a . Note that, in practice, in the display device  1   a , one pixel may include sub-pixels of four colors, namely, a pixel in which the CF  113 R is provided (that is, a red pixel), a pixel in which the CF  113 G is provided (that is, a green pixel), a pixel in which the CF  113 B is provided (that is, a blue pixel), and a pixel in which the CF  113   a  is not provided (that is, a white pixel). However, in the present specification, also a combination of one light emitting element  103  and one CF  113   a  is referred to as simply a pixel, for convenience of description. In  FIG.  1   , for the sake of description, a boundary between pixels is indicated by an alternate long and short dash line. Further, in the display device  1 , sub-pixels of four colors may be arranged in what is called a delta arrangement (see also  FIG.  6    described later). 
     In the first embodiment, as illustrated in the drawing, in each pixel, a CF  113   a  corresponding to the light emitting element  103  is arranged such that the center of the luminescence surface of the light emitting element  103  in a horizontal surface substantially coincides with the center of the CF  113   a.    
     Further, in the display device  1   a , a reflector  119  that reflects the emission light from the light emitting element  103  therebelow is formed above the light emitting element  103  for each pixel. In the illustrated example, the reflector  119  is formed below the CF layer  113 , specifically in the planarizing film  111 . Specifically, the display device  1   a  has a configuration in which, after the protection film  109  is formed, the reflector  119  is formed on the protection film  109  and the planarizing film  111  is formed thereon. Here, in the first embodiment, the reflector  119  may be formed above the light emitting element  103 , and an arrangement position of the reflector  119  in a stacking direction is not limited to this example. The arrangement position of the reflector  119  in the stacking direction, that is, a layer in which the reflector  119  is formed may appropriately be decided in consideration of compatibility between a material of the reflector  119  and a material of each layer constituting the display device  1   a , an ease of manufacturing, a function of the reflector  119  to be described later, or the like. Here, if the function of the reflector  119  to be described later is considered, in order to more efficiently reflect the emission light from the light emitting element  103 , it is preferable that the reflector  119  is formed at a position closer to the light emitting element  103  in the stacking direction. 
     A reflective surface (that is, a lower surface) of the reflector  119  has a recursive structure and has a function of reflecting incident light toward an incident direction. In the first embodiment, as a recursive structure of the reflector  119 , a so-called prism type in which a plurality of corner cube prisms (CCP) are regularly arranged is used. In a case in which the recursive structure is the prism type, for example, the reflector  119  can be formed by appropriately processing a surface of a metallic film in a shape of a prism through a transfer technique, an etching technique or the like. Here, the first embodiment is not limited to this example, and a so-called bead type in which a plurality of beads are dispersedly arranged may be used as the recursive structure of the reflector  119 . In a case in which the recursive structure is the prism type, for example, the reflector  119  is formed by a method of processing a resist material in a spherical shape or a hemispherical shape through a photoresist technique or dispersedly arranging appropriate particles in a resin film or the like. Further, the reflector  119  may be formed at the same time in a series of processes for forming respective layers on the first substrate  101 , or the separately prepared reflector  119  may be boded onto the first substrate  101 . 
     Here, in the first embodiment, in order to reflect light emitted in a direction other than a desired direction among the emission light from the light emitting element  103 , the light emitting element  103  and the reflector  119  are arranged so that the center of the reflector  119  deviates from the center of the luminescence surface of the light emitting element  103  in the horizontal surface. According to this configuration, light entering a region in which the reflector  119  is not formed (that is, a desired direction in which light is desired to be extracted) among the emission light from the light emitting element  103  is directly emitted from the second substrate  117  to the outside without change. On the other hand, light entering a region in which the reflector  119  is formed among the emission light from the light emitting element  103  is reflected by the lower surface of the reflector  119 . In this case, since the reflective surface of the reflector  119  has the recursive structure as described above, the light reflected by the reflector  119  heads off the light emitting element  103 . Then, the light is reflected toward the region in which the reflector  119  is not formed in the surface of the light emitting element  103  (or an interface between lower layers) and is emitted to the outside from the second substrate  117  without change. In  FIG.  1   , a locus of the light beam performing such a behavior is simulatively indicated by a broken arrow. 
     As described above, according to the first embodiment, since the reflector  119  is formed in each pixel, the emission light from the pixel is emitted only from the region in which the reflector  119  is not formed. In other words, by appropriately adjusting the arrangement position of the reflector  119  in the horizontal surface with respect to the luminescence surface of the light emitting element  103 , it is possible to control a light emission direction from each pixel, that is, a viewing angle in each pixel. Further, at this time, since the reflective surface of the reflector  119  has the recursive structure, the light blocked and reflected by the reflector  119  among the emission light from the light emitting element  103  is reflected toward the direction of the light emitting element  103  and is emitted to the outside from the region in which the reflector  119  is not formed. Therefore, it is possible to suppress the decrease in the light extraction efficiency by forming the reflector  119 . As described above, according to the display device  1   a  of the first embodiment, it is possible to improve the light extraction efficiency while realizing a desired viewing angle characteristic for each pixel. 
     In the first embodiment, the arrangement position of the reflector  119  in the horizontal surface in each pixel (that is, an amount of misalignment and a misalignment direction of the center of the reflector  119  with respect to the center of the luminescence surface of the light emitting element  103  in the horizontal surface) may be decided in accordance with the viewing angle required for pixel. At this time, the amount of misalignment and the misalignment direction of the center of the reflector  119  with respect to the center of the luminescence surface of the light emitting element  103  in the horizontal surface may have a distribution in the display surface. The viewing angle required for each pixel differs depending on a use application of the display device  1   a , but it is generally considered that a pixel closer to an outer edge of the display surface is required to have a larger viewing angle in the outer edge direction. Therefore, preferably, the amount of misalignment of the center of the reflector  119  with respect to the center of the luminescence surface of the light emitting element  103  in the horizontal surface may be set to increase as it is closer to the outer edge of the display surface. Further, the misalignment direction of the center of the reflector  119  with respect to the center of the luminescence surface of the light emitting element  103  in the horizontal surface can be set to be a direction opposite to a direction from the center of the display surface toward the pixel since it is possible to obtain the viewing angle with respect to a direction opposite to the misalignment direction in a pixel in which the misalignment. 
     The configuration of the display device  1   a  according to the first embodiment has been described above. Further, in the above-described embodiment, the reflective surface of the reflector  119  has the recursive structure, but the first embodiment is not limited to this example. The reflective surface of the reflector  119  may be a mirror or a scatterer. In a case in which the reflective surface of the reflector  119  is a mirror or a scatterer, a proportion of light returning to the light emitting element  103  among the light reflected by the reflector  119  decreases as compared with the case in which the recursive structure is used. Accordingly, the effect of improving the light extraction efficiency is reduced, but as compared to the case in which a structure with low reflectance (for example, a light absorber or the like) is used in place of the reflector  119 , an effect in that a constant light extraction efficiency is improved can be obtained. 
     Here, in this specification, partial cross-sectional views similar to  FIG.  1    are schematically illustrated in  FIGS.  2  and  4    and  FIGS.  7  to  17    to be described later, and configurations of display devices according to other embodiments and modified examples of respective embodiments will be described. Here, cross-sectional structures illustrated in  FIGS.  1 ,  2 , and  4    and  FIGS.  7  to  17    are those which are schematically illustrated by simplifying an actual configuration. An example of a further detailed structure of the display device according to embodiments and modified examples of the present disclosure will be described later with reference to  FIG.  25   . 
     1-2. Modified Example 
     A modified example of the first embodiment will be described. In the above-described embodiment, the display device  1   a  is a display device of an OCCF scheme in which the CF layer  113  is formed over the first substrate  101  on which the light emitting element  103  is formed. Here, the first embodiment is not limited to this example. The display device according to the first embodiment may be a display device of a so-called facing CF scheme which is manufactured by bonding a second substrate with a CF layer formed thereon to a first substrate on which a light emitting element is formed so that the CF layer faces the light emitting element. 
     A configuration of a display device of a facing CF scheme which is a modified example of the first embodiment will be described with reference to  FIG.  2   .  FIG.  2    is a cross-sectional view illustrating a configuration example of a display device of a facing CF scheme which is a modified example of the first embodiment. Further, a display device  1   b  according to the present modified example differs from the display device  1   a  according to the first embodiment in a configuration in which a configuration above the protection film  109  is different due to a difference in manufacturing method and is similar in the other configuration to the display device  1   a  according to the first embodiment. Therefore, in the following description of the display device  1   b  according to the present modified example, different portions from the display device  1   a  described above will be mainly described, and detailed description of portions duplicating the display device  1   a  will be omitted. 
     Referring to  FIG.  2   , in the display device  1   b  according to the present modified example, a light emitting element  103 , a first member  107 , and a protection film  109  are stacked on a first substrate  101  in the described order. Further, a CF layer  113  and a reflector  119  are formed on a second substrate  117 . Further, in the present modified example, an adhesive layer  123  for causing the CF layer  113  and the reflector  119  to adhere to each other is formed between the CF layer  113  and the reflector  119 . Then, the second substrate  117  is bonded to the first substrate  101  via a sealing material  121  made of, for example, epoxy resin so that each of the light emitting elements  103  faces the CF  113   a  and the reflector  119  of each color, so that the display device  1   b  is manufactured. 
     Here, in a case in which the layer in which the reflector  119  is formed (the CF layer  113  in the case of the display device  1   b ) and the reflector  119  are formed of a similar material, adhesion therebetween is considered to be good, and thus the adhesive layer  123  need not be necessarily formed. At this time, if the layer in which the reflector  119  is formed and the process of forming the reflector  119  are similar, it is possible to consecutively form the components, and thus there are advantages in that excellent adhesion can be obtained, and the manufacturing process can be simplified. For example, as will be described below in detail ( 6 . Specific configuration example of display device), the CF layer  113  can be formed by processing a resist material through a photoresist technique. Therefore, in a case in which the reflective surface of the reflector  119  is the recursive structure of the bead type, and the recursive structure is formed of a resist material, the CF layer  113  and the reflector  119  can be formed by a similar process using a similar material if the reflector  119  can be formed on the CF layer  113  as in the display device  1   b . Therefore, in this case, the adhesive layer  123  need not be necessarily formed. 
     On the other hand, as described above, since the reflector  119  can have various configurations in the first embodiment, materials thereof are also various. Therefore, in a case in which the layer in which the reflector  119  is formed and the reflector  119  are made of different materials, the adhesion therebetween is unlikely to be necessarily excellent due to the compatibility of the materials. Therefore, in this case, it is preferable that the adhesive layer  123  be formed between both components as in the display device  1   b . In the illustrated example, since the adhesive layer  123  is formed, it is possible to cause the CF layer  113  and the reflector  119  to adhere to each other suitably. In other words, whether or not the adhesive layer  123  is formed between the reflector  119  and the layer in which the reflector  119  is formed may be appropriately selected in consideration of materials of both components, a forming process, and the like. 
     The configuration of the display device  1   b  according to the present modified example has been described above. Similarly to the display device  1   a  according to the first embodiment, in the display device  1   b  having the above-described configuration, the reflector  119  is formed for each pixel to reflect the light emitted in the direction other than the desired direction among the emission light from the light emitting element  103 . Therefore, similarly to the display device  1   a , it is possible to obtain an effect in that it is possible to improve the light extraction efficiency while realizing a desired viewing angle characteristic for each pixel. 
     Here, in the facing CF scheme, since the display device  1   b  is manufactured by boding the second substrate  117  in which the CF layer  113  is formed to the first substrate  101  in which the light emitting element  103  is formed, there is a limit in the accuracy of alignment with the luminescence surface of each light emitting element  103  and each CF in the CF layer  113 . On the other hand, as in the display device  1   a , in the OCCF scheme, since the CF layer  113  is formed directly above the first substrate in which the light emitting element  103  is formed, it is possible to perform alignment between the luminescence surface of each light emitting element  103  and each CF of the CF layer  113  with a high degree of accuracy as compared with the facing CF scheme. 
     Further, as described above, in the display device  1   a  which is the OCCF scheme, the reflector  119  can be formed above the protection film  109 , whereas in the display device  1   b  which is the facing CF scheme, the reflector  119  is formed directly below the CF layer  113 . Therefore, in the case of the display device  1   a , it is possible to further reduce a distance between the light emitting element  103  and the reflector  119 . Therefore, it is possible to further increase the proportion at which the emission light from the light emitting element  103  is reflected by the reflector  119 , further reduce a path until the emission light from the light emitting element  103  is reflected by the reflector  119  and returns to the light emitting element  103 , and suppress attenuation in the emission light in the path. 
     On the other hand, since many organic EL displays are manufactured by the facing CF scheme, if the reflector  119  is considered to be newly added without substantially changing the current process, there is a possibility that the display device  1   b  which is of the facing CF scheme can be more simply implemented than the display device  1   a  which is the OCCF scheme. 
     In the first embodiment, the configuration of either the display device  1   a  or the display device  1   b  to be applied may be appropriately decided in consideration of the advantages when the facing CF scheme and the OCCF scheme described above are employed, respectively. 
     2. Second Embodiment 
     2-1. Background to Second Embodiment 
     Before a second embodiment of the present disclosure is described, the background that the inventors invented the second embodiment will be described in order to facilitate understanding the second embodiment. 
     In recent years, display devices having a relatively small area display surface (for convenience, hereinafter referred to simply as small display devices) such as HMDs or EVFs of digital camera are increasingly mounted on electronic apparatuses. In such an electronic apparatus, a light beam from a display surface of the display device is caused to form an image on an eyeball of a user via an optical system of a lens, a mirror, a diffraction grating, etc. On the other hand, these days, the demand for further reduction in the weight and size of the electronic apparatus in order to reduce the burden on the user is great. To achieve reduction in the weight and size of the electronic apparatus, also the mounted optical system is required to achieve even more downsizing. 
       FIG.  3    is a diagram simulatively showing the locus of a light beam from a small-sized display device in an electronic apparatus to an eyeball of a user in a case where an optical system is downsized. As shown in  FIG.  3   , to achieve reduction in the weight and size of the electronic apparatus, it is necessary to downsize an optical system  205  and make narrower the distance between the optical system  205  and a display device  1 . Further, since the optical system  205  cannot be made a complicated configuration, it is difficult to supplement the viewing angle characteristics of the display device  1  by modifying the configuration of the optical system  205 . Therefore, a light beam with a wider angle (that is, a light beam with a wider viewing angle) among the light beams emitted from a display surface  201  of the display device  1  is guided to an eyeball  203  of a user while keeping almost the same characteristics as those when the light beam is emitted from the display surface  201  of the display device  1 . For the above reasons, in a case where it is attempted to downsize the optical system  205  in an electronic apparatus in which the small-sized display device  1  is used, it is required that, in order to provide high quality display to the user, the display device  1  be able to emit a light beam having desired characteristics even at a wider viewing angle, that is, have more excellent wide viewing angle characteristics. 
     Here, as the display devices  1   a  and  1   b  described above, a display device of a system in which a pixel is formed by providing a CF on a white light emitting element and color display is performed by performing color conversion based on the CF on a pixel basis is commonly known. If it is attempted to achieve a wide viewing angle in a display device of such a system, the occurrence of what is called color mixing in which light from one light emitting element is incident on the CF of an adjacent pixel and light emission of a desired color is not obtained is a problem. 
     In this regard, various methods to suppress color mixing have been proposed until now. For example, there is known a method in which the distance between a light emitting element and a CF (facing gap) is set small as compared to the pixel size. Alternatively, there is known a method in which the area of a luminescence surface of a light emitting element is set much smaller than the area of a CF (the area in a plane perpendicular to the stacking direction). 
     However, these methods have the following disadvantages. For example, if it is attempted to obtain a structure of a narrow facing gap in a case where the display device is an organic EL display, it is necessary that an electrode layer, a protection layer, and a CF bonding layer be made thin films; hence, there is a concern that the luminescence characteristics and the protectiveness of the OLED will be greatly reduced. Further, reducing the area of the luminescence surface of the light emitting element leads to reducing the aperture ratio; hence, there is a concern that the luminance will be greatly reduced. 
     As described hereinabove, it is desired for a small-sized display device, such as one mounted on an electronic apparatus, to achieve even more improvement in wide viewing angle characteristics; however, in methods for achieving a wide viewing angle while suppressing color mixing that have been commonly proposed until now, there has been a concern that other characteristics will be reduced. In view of the circumstances mentioned above, the present inventors conducted extensive studies on technology for the display devices  1   a  and  1   b  according to the first embodiment described above that can suppress the occurrence of color mixing and can further improve wide viewing angle characteristics without causing reduction in other characteristics like those described above, such as a reduction in luminance; and consequently have conceived the second embodiment. In other words, in the second embodiment of the present disclosure, it is possible to provide a display device capable of obtaining an effect in that a wide viewing angle characteristic is further improved, and the occurrence of color mixing is further suppressed in addition to the effects obtained by the display devices  1   a  and  1   b  according to the first embodiment described above. 
     2-2. Configuration of Display Device 
     A configuration of a display device according to the second embodiment of the present disclosure will be described with reference to  FIG.  4   .  FIG.  4    is a cross-sectional view illustrating a configuration example of the display device according to the second embodiment. Further, a display device  1   c  according to the second embodiment differs from the display device  1   a  according to the first embodiment described above in that a configuration of the CF layer  113  is different and is similar in the other configurations to the display device  1   a  according to the first embodiment. Therefore, in the following description of the display device  1   c  according to the second embodiment, different portions from the display device  1   a  described above will be mainly described, and detailed description of portions duplicating the display device  1   a  will be omitted. 
     Referring to  FIG.  4   , the display device  1   c  according to the second embodiment is a display device of an OCCF scheme in which a light emitting element  103 , a first member  107 , a protection film  109 , a planarizing film  111 , and a CF layer  113  are stacked on the first substrate  101  in the described order, similar to the display device  1   a  according to the first embodiment. In this configuration, a second substrate  117  is bonded to the CF layer  113  of the uppermost layer via a sealing resin film  115 , so that a display device  1   c  is manufactured. 
     In the display device  1   c , a configuration of the CF layer  113  differs from that in the display device  1   a . Specifically, in the display device  1   a , in each pixel, the CF  113   a  corresponding to the light emitting element  103  is arranged so that the center of the luminescence surface of the light emitting element  103  in the horizontal surface substantially coincides with the center of the CF  113   a . On the other hand, in the display device  1   c  according to the present embodiment, a light emitting element  103  and the CF  113   a  corresponding to the light emitting element  103  are arranged such that the positions of the center of the luminescence surface of the light emitting element  103  and the center of the CF  113   a  are relatively shifted by a prescribed distance L in the horizontal plane, in at least a partial region in the display surface. In the illustrated example, the center of the CF  113   a  corresponding to the light emitting element  103  is placed to be shifted relative to the center of the luminescence surface of the light emitting element  103  in the right direction of the drawing sheet. 
     Note that, in the following description, the relative misalignment in the horizontal plane between the center of the luminescence surface of a light emitting element  103  and the center of the CF  113   a  corresponding to the light emitting element  103  is referred to also as simply a relative misalignment between the light emitting element  103  and the CF  113   a . Further, the amount of relative misalignment L and the misalignment direction of the CF  113   a  to the center of the luminescence surface of the light emitting element  103  in the horizontal plane in the relative misalignment between the light emitting element  103  and the CF  113   a  are referred to also as simply the amount of misalignment L of the CF  113   a  and the misalignment direction of the CF  113   a , respectively. 
     In the display device  1   c , since the CF layer  113  is formed as described above, it is possible to obtain a wider viewing angle for each pixel. For example, a case in which green light is desired to be obtained as the light from the pixel to which the light emitting element  103  of interest now belongs is considered. If the light emitted from the light emitting element  103  in a relatively wide viewing angle direction as indicated by a solid arrow in the drawing is considered, in a case in which relative misalignment does not occur between the light emitting element  103  and the CF  113   a  as in the first embodiment, the light emitted at the angle is considered to pass through a blue CF  113 B of an adjacent pixel instead of a green CF  113 G through which it is desired to pass originally. In other words, color mixing occurs, and the desired green light is unable to be obtained. On the other hand, as illustrated in  FIG.  4   , in the configuration according to the second embodiment, a relative position of the CF  113   a  to the light emitting element  103  is shifted by the amount of misalignment L in the horizontal surface, and thus the light emitted from the light emitting element  103  at the above angle passes through the CF  113 G and is emitted from the display device  1 . Therefore, the desired green light can be obtained. As described above, in the configuration according to the second embodiment, the green pixel including the light emitting element  103  of interest is regarded as having a wider viewing angle in a right direction on a page plane which is a direction in which the CF  113 G is shifted. 
     Thus, in the second embodiment, a relative misalignment between the light emitting element  103  and the CF  113   a  is created for a pixel, and thereby the viewing angle characteristics of the pixel in the misalignment direction of the CF  113   a  can be improved. 
     Here, the viewing angle characteristics required of pixels vary in accordance with the position in the display surface of the display device  1   c . Therefore, in the second embodiment, the amount of misalignment L and the misalignment direction of the CF  113   a  in each pixel are set such that a desired viewing angle is obtained in the pixel in accordance with the position of the light emitting element  103  (that is, the position of the pixel) in the display surface. That is, in the second embodiment, each of the amount of misalignment and the misalignment direction of the CF  113   a  has a distribution in the display surface. 
       FIG.  5    is a diagram for describing distributions of amounts of misalignment L and misalignment directions of CFs  113   a  in the display surface of the display device  1   c . Here, a case where, when mounted on an electronic apparatus, the display device  1   c  is installed such that the display surface  201  faces the optical system  205  with a relatively narrow distance, as shown in  FIG.  3   , is envisaged. In this case, as shown in  FIG.  5   , for emission light from a pixel placed in region  207  that is substantially near the center in the display surface  201  of the display device  1   c , it is sufficient that emission light in a direction substantially perpendicular to the luminescence surface of the light emitting element  103  be incident on the optical system  205 ; hence, the emission light from a pixel placed in region  207  does not need to have considerably wide viewing angle characteristics. Therefore, in a pixel placed in region  207 , the light emitting element  103  and the CF  113   a  are arranged such that a relative misalignment between the light emitting element  103  and the CF  113   a  is not created (that is, the amount of misalignment L is set to L=0), like in the configuration according to the first embodiment. 
     On the other hand, for emission light from a pixel placed in region  209  that is near the outer periphery in the display surface  201  of the display device  1   c , it is necessary that light emitted toward the outer edge of the display surface  201  be incident on the optical system  205 ; hence, the emission light from a pixel placed in region  209  needs to have wider viewing angle characteristics toward the outer edge of the display surface  201  (in the illustrated example, in the right direction of the drawing sheet). Therefore, in a pixel placed in region  209 , the light emitting element  103  and the CF  113   a  are arranged such that a relative misalignment between the light emitting element  103  and the CF  113   a  is created by a prescribed amount of misalignment L (L&gt;0), like in the configuration described with reference to  FIG.  4   . Further, in this event, the misalignment direction of the CF  113   a  is set to a direction from the center of the display surface  201  to the place where the pixel is located. Thereby, in a pixel placed in region  209 , wider viewing angle characteristics are obtained toward the outer edge of the display surface  201 . 
       FIG.  5    shows only the configuration of pixels in region  207  that is substantially near the center in the display surface  201  and region  209  that is near the outer periphery; however, in the second embodiment, pixels are provided in a gradational manner in accordance with the position in the display surface  201 , that is, in such a manner that the amount of misalignment L of the CF  113   a  becomes larger as the position shifts from the center of the display surface  201  toward the outer edge. For example, the inside of the display surface  201  is divided into a plurality of regions, and the amount of misalignment L is set for each region in accordance with the position in the display surface  201  of the region. Further, also the misalignment direction of the CF  113   a  is set for each region. Here, in the second embodiment, the misalignment direction of the CF  113   a  is set simply to either one of the horizontal direction and the vertical direction of the display surface  201 . By this configuration, the distribution of misalignment directions of CFs  113   a  in the plane of the display surface  201  can be managed more easily; thus, the design is not complicated. 
     Note that, in the above example, an arrangement of the display device  1   c  and the optical system  205  like that shown in  FIG.  3    is envisaged, and hence pixels are provided such that the amount of misalignment L of the CF  113   a  becomes larger as the position shifts from the center of the display surface  201  toward the outer edge; but the second embodiment is not limited to this example. The way of division of regions, and the amount of misalignment L and the misalignment direction of the CF  113   a  in each region (that is, the distributions of amounts of misalignment L and misalignment directions of CFs  113   a  in pixels in accordance with the position in the display surface  201 ) may be set such that a desired viewing angle is obtained for each pixel in the display surface  201 , in accordance with the positional relationship between the display device  1   c  and the optical system  205  in the electronic apparatus, as appropriate. Specifically, the misalignment direction of the CF  113   a  may be set to a direction in which a viewing angle is intended to be obtained in the horizontal plane (that is, the inclination direction from the direction perpendicular to the luminescence surface to the direction of a desired viewing angle). A specific method for setting the amount of misalignment L of the CF  113   a  is described in detail later in (4. With regard to amount of misalignment of CF) below. 
     In order for the amount of misalignment L and/or the misalignment direction of the CF  113   a  to be changed between regions, a transition region in which the amount of misalignment L and/or the misalignment direction of the CF  113   a  changes may be provided between regions.  FIG.  6    is a diagram for describing a transition region in which the amount of misalignment L and/or the misalignment direction of the CF  113   a  changes.  FIG.  6    schematically shows the configuration of, in the display device  1   c , near the boundary between two regions between which the amount of misalignment L of the CF  113   a  is different.  FIG.  6    is a top view, and an arrangement of the CF  113   a  and an arrangement of the light emitting element  103  and the reflector  119  are schematically indicated by broken lines. Further, in  FIG.  6   , a prism type having a three-dimensional prism shape of a right triangular pyramid is illustrated as an example of the reflector  119 . 
     In  FIG.  6   , region  303  in which the amount of misalignment L of the CF  113   a  is 0, region  305  in which the amount of misalignment L of the CF  113   a  adjacent to region  303  is not zero but a predetermined nonzero value, and transition region  301  formed between regions  303  and  305  are illustrated as examples. As illustrated in the drawing, transition region  301  is formed as a region in which the CF  113   a  is not formed in the CF layer  113 . Accordingly, in region  305 , the center of the CF  113   a  is arranged to be shifted from the center of the luminescence surface of the light emitting element  103  in the horizontal surface by the amount of misalignment L&gt;0 in the direction in which an interval is formed between the CFs  113   a  in the CF layer  113 . Similar transition region  301  is formed between other regions (not illustrated), and thus it is possible to change the amount of misalignment L and/or the misalignment direction for each region. 
     Note that, in the above example, the inside of the display surface  201  is divided into a plurality of regions, and the amount of misalignment L and the misalignment direction are set for each region in accordance with the position in the display surface  201  of the region; however, the second embodiment is not limited to this example. For example, the amount of misalignment L and the misalignment direction may be set not on a region basis but on a pixel basis, and the amount of misalignment L and the misalignment direction may be changed in a continuous manner between pixels in accordance with the position in the display surface  201  of the pixel. Also in this case, the amount of misalignment L and the misalignment direction of the CF  113   a  in each pixel may be set in accordance with the positional relationship between the display device  1   c  and the optical system  205  in the electronic apparatus in such a manner that a desired viewing angle is obtained for each pixel in the display surface  201 , as appropriate. 
     Here, in a case in which relative misalignment is caused between the light emitting element  103  and the CF  113   a  for a certain pixel, it is concerned that in the pixel, the CF  113   a  of an adjacent pixel different from a desired color exists immediately above the light emitting element  103  in a direction (the left direction on the paper plane in the example illustrated in  FIG.  4   ) opposite to the misalignment direction of the CF  113   a , and thus the light emitted in the front direction does not pass through the CF  113   a  of the desired color, and the color mixing is likely to occur more easily. In this regard, in the second embodiment, the misalignment direction of the center of the reflector  119  with respect to the center of the luminescence surface of the light emitting element  103  in the horizontal surface is set to the direction opposite to the misalignment direction of the CF  113   a . In other words, the reflector  119  is arranged on a side opposite to the direction in which the CF  113   a  is shifted with respect to the luminescence surface of the light emitting element  103  in the horizontal surface. Accordingly, the light emitted from the light emitting element  103  in a direction opposite to the direction in which the viewing angle is desired to be obtained is reflected by the reflector  119  and directed toward the luminescence surface of the light emitting element  103 . Then, the light is reflected again in the direction in which the reflector  119  is not formed in the luminescence surface (or the interface between the lower layers), that is, the direction in which a desired viewing angle is desired to be obtained which is the misalignment direction of the CF  113   a  and is emitted from the second substrate  117  to the outside as light of a desired color with a desired viewing angle. In  FIG.  4   , a locus of the light beam performing such a behavior is simulatively indicated by a broken line arrow. 
     Specifically, an installation position of the reflector  119  in an in-plane direction within a pixel is set, for example, so that an end on a side far from the center of the light emitting element  103  corresponding to itself (an end in the left direction on the paper plane in  FIG.  4   ) is positioned between an end of the light emitting element  103  corresponding to itself (a position indicated by a dotted line X in  FIG.  4   ) and the center of a region between adjacent pixels (a position indicated by an alternate long and short dash line Y in  FIG.  4   ). This is one in which the fact that the emission light from the light emitting element  103  in the adjacent pixel is not reflected by the reflector  119  is considered. Further, the installation position of the reflector  119  in the in-plane direction within the pixel is set, for example, so that an end on a side closer to the center of the light emitting element  103  corresponding to itself (an end in the right direction on the page plane in  FIG.  4   ) does not enter its own pixel side further than the boundary with the CF  113   a  of the adjacent pixel (a position indicated by a dotted line Z in  FIG.  4   ). This is one in which the fact that the emission light directed directly toward the CF  113   a  corresponding to the light emitting element  103  from the light emitting element  103  is not reflected by the reflector  119  formed corresponding to itself is considered. Since the reflector  119  is installed as described above, it is possible to suitably reflect the emission light from the light emitting element  103  corresponding to the light emitting element  103  without leaking to the adjacent pixel without disturbing the emission light directly from the light emitting element  103  of an adjacent pixel corresponding to itself or the emission light directed directly toward the CF  113   a  corresponding to itself from the light emitting element  103  corresponding to itself (that is, without degrading the light extraction efficiency more than necessary). 
     Further, in order to effectively cause the function of the reflector  119  to be fulfilled, in the second embodiment, it is preferable that the light emitting element  103 , the CF  113   a , and the reflector  119  are arranged so that the distribution of the amount of misalignment of the center of the reflector  119  in the display surface with respect to the center of the luminescence surface of the light emitting element  103  in the horizontal surface is proportional to the distribution of the amount of misalignment of the CF  113   a  in the display surface, and the distribution of the misalignment direction of the center of the reflector  119  in the display surface with respect to the center of the luminescence surface of the light emitting element  103  in the horizontal surface is a direction opposite to the distribution of the misalignment direction of the CF  113   a  in the display surface. 
     As described above, according to the second embodiment, by causing the relative misalignment to occur between the light emitting element  103  and the CF  113   a , it is possible to obtain a wide viewing angle characteristic while suppressing the occurrence of the color mixing for each pixel. Further, since the reflector  119  is installed, the light which is emitted from the light emitting element  103  in a direction opposite to the direction in which the viewing angle is desired to be obtained can be guided toward the direction in which the viewing angle is desired to be obtained, it is possible to improve the light extraction efficiency of a desired color while suppressing the occurrence of the color mixing. In other words, according to the second embodiment, since the relative misalignment is caused between the light emitting element  103  and the CF  113   a  for each pixel, and the reflector  119  is formed for each pixel as well, it is possible to obtain a wider viewing angle characteristic in a desired direction, suppress the occurrence of the color mixture, and improve the light extraction efficiency. 
     Further, in the second embodiment, since an improvement in viewing angle characteristics can be achieved by a relative misalignment between the light emitting element  103  and the CF  113   a , there is no need to employ configurations that have been proposed until now for an improvement in viewing angle characteristics, such as those described in (2-1. Background with which second embodiment is conceived) above (for example, the narrowing of the facing gap and the downsizing of the area of the luminescence surface). Hence, the viewing angle characteristics can be improved without reducing the luminescence characteristics or the protectiveness of the light emitting element  103  (OLED), or causing a reduction in luminance. 
     Further, a relative misalignment between the light emitting element  103  and the CF  113   a  can be obtained by merely changing the configuration of CFs  113   a  during the formation of the CF layer  113 , and therefore the display device  1   c  according to the second embodiment can be fabricated easily without increasing the number of manufacturing steps. Thus, desired effects can be obtained without increasing the production cost. 
     Further, in general, in a case where color shifting or color mixing has occurred, color correction processing may be performed by a driving circuit. According to the second embodiment, such color correction processing does not need to be performed because the occurrence of color shifting and color mixing can be suppressed favorably while the viewing angle characteristics are improved. Therefore, a driving circuit can be obtained more simply, and thus the circuit scale of the driving circuit can be made smaller. 
     Note that, although in the second embodiment described hereinabove the misalignment direction of the CF  113   a  is set to only either one of the horizontal direction and the vertical direction of the display surface  201 , the second embodiment is not limited to this example. For example, the misalignment direction of the CF  113   a  may be a two-dimensional arbitrary direction in the horizontal plane. By this configuration, the misalignment direction of the CF  113   a  can be set more finely for each pixel, and thus the adjustment of the viewing angle on a pixel basis can be performed more strictly. 
     The configuration of the display device  1   c  according to the second embodiment has been described above. 
     2-3. Modified Examples 
     Several modified examples of the second embodiment will be described. 
     2-3-1. First Modified Example 
       FIG.  7    is a cross-sectional view illustrating a configuration example of a display device according to a first modified example of the second embodiment. Referring to  FIG.  7   , a display device  1   d  according to the first modified example differs from the display device  1   c  according to the second embodiment in that an adhesive layer  123  is formed between the protection film  109  and the reflector  119 . Further, the display device  1   d  according to the first modified example has a configuration similar to that of the display device  1   c  except that the adhesive layer  123  is formed between the protection film  109  and the reflector  119 . Therefore, in the description of the display device  1   d , detailed description of portions duplicating the display device  1   c  will be omitted. 
     In the above-described embodiment, the display device  1   c  includes the reflector  119  formed on the protection film  109 , similarly to the display device  1   a  according to the first embodiment. Here, depending on a material of the protection film  109  and a material of the reflector  119 , it is concerned that adhesion between the protection film  109  and the reflector  119  may decrease. Therefore, in the second embodiment, when the reflector  119  is formed on the protection film  109  as in the first modified example, the adhesive layer  123  may be formed between the protection film  109  and the reflector  119 . Since the adhesive layer  123  is formed, it is possible to connect the protection film  109  and the reflector  119  more suitably, and thus a more stable display device  1   d  can be obtained. 
     2-3-2. Second Modified Example 
       FIG.  8    is a cross-sectional view illustrating a configuration example of a display device according to a second modified example of the second embodiment. Referring to  FIG.  8   , a display device  1   e  according to the second modified example differs from the display device  1   c  according to the second embodiment described above in that an arrangement position of the reflector  119  in the stacking direction is different. Further, the display device  1   e  according to the second modified example has a configuration similar to that of the display device  1   c  except that the arrangement position of the reflector  119  in the stacking direction is different. Therefore, in the description of the display device  1   e , detailed description of portions duplicating the display device  1   c  will be omitted. 
     Specifically, in the display device  1   e , a reflector  119  is formed on the CF layer  113  after the CF layer  113  is formed. At this time, in the present modified example, the adhesive layer  123  is formed between the CF layer  113  and the reflector  119 . Since the adhesive layer  123 , it is possible to cause the CF layer  113  and the reflector  119  to adhere to each other more suitably, and thus a more stable display device  1   e  can be obtained. Here, in a case in which it is possible to cause the CF layer  113  and the reflector  119  to adhere to each other more suitably due to compatibility of the material of the CF layer  113  and the material of the reflector  119  or a case in which the CF layer  113  and the reflector  119  can be consecutively formed by a similar process using a similar process, the adhesive layer  123  need not be necessarily formed. 
     The second substrate  117  is bonded to the first substrate  101  in the state in which the reflector  119  is formed on the CF layer  113  via the sealing resin film  115 , so that the display device  1   e  is manufactured. 
     Similarly to the second modified example, in the second embodiment, the arrangement position of the reflector  119  in the stacking direction is not limited. The reflector  119  may be formed above the light emitting element  103  or may be formed at an arbitrary position in the stacking direction. 
     2-3-3. Third to Fifth Modified Examples 
     The display devices  1   c ,  1   d , and  1   e  according the second embodiment described above and the first and second modified examples are the display devices of the OCCF scheme. Here, the second embodiment is not limited to this example, and the display device according to the second embodiment may be a display device of a facing CF scheme. 
     Configurations of display devices of facing CF scheme which are third to fifth modified examples of the second embodiment will be described with reference to  FIGS.  9  to  11   .  FIGS.  9  to  11    are cross-sectional views illustrating configuration examples of display devices of the facing CF scheme which are the third to fifth modified example of the second embodiment. 
     First, referring to  FIG.  9   , the configuration of the display device in accordance with the third modified example will be described. Here, a display device  1   f  according to the third modified example differs from the display device  1   c  according to the second embodiment illustrated in  FIG.  4    in that a configuration above the protection film  109  is different due to the difference in the manufacturing method and is similar in the other configuration to the display device  1   c  according to the second embodiment. Therefore, in the description of the display device  1   f  according to the third modified example, different portions from the display device  1   c  described above will be mainly described, and detailed description of portions duplicating the display device  1   c  will be omitted. 
     Referring to  FIG.  9   , in the display device  1   f  according to the third modified example, a light emitting element  103 , a first member  107 , and a protection film  109  are stacked on the first substrate  101  in the described order. Further, a CF layer  113  and a reflector  119  are formed on a second substrate  117 . At this time, for example, the reflector  119  can be consecutively formed by a similar photolithography technique using a similar resist material to the CF layer  113 . Further, the second substrate  117  is bonded to the first substrate  101  via a sealing material  121  so that each of the light emitting elements  103  faces the CF  113   a  and the reflector  119  of each color, so that the display device  1   f  is manufactured. 
     Next, a configuration of a display device according to the fourth modified example will be described with reference to  FIG.  10   . Referring to  FIG.  10   , a display device  1   g  according to the fourth modified example differs from the display device  1   f  according to the third modified example illustrated in  FIG.  9    in that an adhesive layer  123  is formed between the protection film  109  and the reflector  119 . Further, the display device  1   d  according to the fourth modified example has a configuration similar to that of the display device  1   f  except that the adhesive layer  123  is formed between the protection film  109  and the reflector  119 . Therefore, in the description of the display device  1   g , detailed description of portions duplicating the display device  1   f  will be omitted. 
     Since the adhesive layer  123  is formed, it is possible to cause the CF layer  113  and the reflector  119  to adhere to each other excellently, and the stability of the display device  1   g  can be enhanced. In a case in which the reflector  119  is formed of a material different from a material of the CF layer  113  and/or by a different process after the CF layer  113  is formed, adhesion between the reflector  119  and the CF layer  113  may not be necessarily be excellent, and thus it is preferable to form the adhesive layer  123 . 
     Next, a configuration of a display device according to the fifth modified example will be described with reference to  FIG.  11   . Referring to  FIG.  11   , a display device  1   h  according to the fifth modified example differs from the display device  1   f  according to the third modified example in that an arrangement position of the reflector  119  in the stacking direction is different. Further, the display device  1   h  according to the fifth modified example has a configuration similar to that of the display device  1   f  except that the arrangement position of the reflector  119  in the stacking direction is different. Therefore, in the description of the display device  1   h , detailed description of portions duplicating with display device  1   f  will be omitted. 
     Specifically, as illustrated in  FIG.  11   , in the display device  1   h , a reflector  119  is formed immediately above the CF layer  113 . More specifically, in the display device  1   h , the reflector  119  is formed on the second substrate  117 , a planarizing film  125  is formed thereon, and then the CF layer  113  is formed. Further, the second substrate  117  is bonded to the first substrate  101  in which the light emitting element  103 , the first member  107 , and the protection film  109  are stacked in the described order such that each of the light emitting elements  103  faces the CF  113   a  and the reflector  119  of each color, so that the display device  1   h  is manufactured. 
     The configurations of the display devices  1   d ,  1   e ,  1   f ,  1   g , and  1   h  according to the first to fifth modified examples of the second embodiment has been described above. The display devices  1   d ,  1   e ,  1   f ,  1   g , and  1   h  having the above-described configurations have both the configuration in which there is relative misalignment between the light emitting element  103  and the CF  113   a  for each pixel, similarly to the display device  1   c  according to the second embodiment and the configuration in which the reflector  119  is formed for each pixel. Therefore, similarly to the display device  1   c , it is possible to obtain a wide viewing angle characteristic in a desired direction for each pixel, suppress the occurrence of the color mixing, and improve the light extraction efficiency 
     3. Third Embodiment 
     3-1. Configuration of Display Device 
     A configuration of a display device according to a third embodiment of the present disclosure will be described with reference to  FIG.  12   .  FIG.  12    is a cross-sectional view illustrating a configuration example of the display device according to the third embodiment. 
     Referring to  FIG.  12   , a display device  1   i  according to the third embodiment differs from the display device  1   c  according to the second embodiment illustrated in  FIG.  4    described above in that a shape of a pixel defining film  105   a  is different. Specifically, in the display device  1   i , the pixel defining film  105   a  is formed to have a relatively large film thickness. Further, a side wall of the opening formed corresponding to the light emitting element  103  of the pixel defining film  105   a  has a tapered shape in which an area of the opening in the horizontal surface increases as it goes upward. 
     The display device  1   i  has a configuration similar to that of the display device  1   c  described above except that the shape of the pixel defining film  105   a  is different. Therefore, in the following description of the display device  1   i , portions different from the display device  1   c  will be mainly described, and detailed description of portions duplicating the display device  1   c  will be omitted. 
     Specifically, similarly to the display device  1   c , in the display device  1   i , a first member  107  is formed to bury the opening (that is, a region immediately above the light emitting element  103 ) formed in the pixel defining film  105   a . Thereafter, a protection film  109  is formed, and a reflector  119  is formed on the protection film  109 . Then, a planarizing film  111  and a CF layer  113  are formed thereon. A second substrate  117  is bonded to the CF layer  113  of the uppermost layer via a sealing resin film  115  in the first substrate  101  on which the respective layers are formed, so that the display device  1   a  is manufactured. As described above, the display device  1   i  is a display device of the OCCF scheme. 
     Here, in the display device  1   i , a material of the pixel defining film  105   a  and a material of the first member  107  are selected so that a refractive index of the first member  107  is larger than a refractive index of the pixel defining film  105   a . Accordingly, at least part of light propagated through the first member  107  is reflected on the surface of the pixel defining film  105   a  facing the first member  107 . In other words, the surface of the pixel defining film  105   a  facing the first member  107  functions as a light reflecting section (reflector). 
     At this time, as described above, the side wall of the opening formed above the light emitting element  103  of the pixel defining film  105   a  has a tapered shape in which the area of the opening gradually increases as it goes upward, and thus the light directed toward the side wall of the opening of the pixel defining film  105   a  among the emission light from the light emitting element  103  is reflected upward, passes through the desired CF  113   a , and is emitted to the outside from the second substrate  117 . In  FIG.  12   , a locus of such a light beam is simulatively indicated by an arrow of an alternate long and two short dashes line. As described above, according to the third embodiment, it is possible to further improve the light extraction efficiency since the reflector is formed. 
     Further, in the display device  1   i , the relative misalignment is caused between the light emitting element  103  and the CF  113   a  for each pixel similarly to the second embodiment, and the reflector  119  is formed above the light emitting element  103  at a position corresponding to a direction opposite to the misalignment direction of the CF  113   a  with respect to the luminescence surface of the light emitting element  103  in the horizontal surface. Accordingly, the light directed toward the side wall of the opening of the pixel defining film  105   a  in the direction in which the reflector  119  is formed (that is, the direction opposite to the misalignment direction of the CF  113   a ) among the emission light from the light emitting element  103  is reflected upward and is reflected by the lower surface of the reflector  119 . Therefore, the incidence of light onto the CF  113   a  of an adjacent pixel different from a desired color, that is, the occurrence of the color mixing is prevented. Further, since the reflector  119  has the recursive structure, the light reflected by the lower surface of the reflector  119  advances toward the luminescence surface of the light emitting element  103  via the side wall of the opening of the pixel defining film  105   a , is reflected again by the luminescence surface (the interface between the lower layers), reflected again toward the direction in which the reflector  119  is not formed, that is, the direction in which a desired viewing angle is desired to be obtained which is the misalignment direction of the CF  113   a , and emitted to the outside from the second substrate  117  as light of a desired color with a desired viewing angle. In  FIG.  12   , a locus of a light beam performing such a behavior is simulatively indicated by a broken arrow. 
     The configuration of the display device  1   i  according to the third embodiment has been described above. As described above, according to the third embodiment, the reflector that reflects the emission light from the light emitting element  103  upward is added to the configuration of the display device  1   c  according to the second embodiment. Therefore, according to the third embodiment, in addition to the effect obtained by the second embodiment, it is also possible to obtain the effect of further improving the light extraction efficiency. 
     3-2. Modified Examples 
     Several modified examples of the third embodiment will be described. Here, display devices  1   j ,  1   k ,  1   l ,  1   m , and  1   n  according to first to fifth modified examples of the third embodiment which will be described below have configurations in which the reflector is added to the configurations of the display device  1   d ,  1   e ,  1   f ,  1   g , and  1   h  according to the first to fifth modified examples of the second embodiment, respectively. Since the display devices  1   j ,  1   k ,  1   l ,  1   m , and  1   n  have configurations similar to the display devices  1   d ,  1   e ,  1   f ,  1   g , and  1   h  except that the reflector is added, in the following description of the display devices  1   j ,  1   k ,  1   l ,  1   m , and  1   n , detailed description of the configurations will be omitted. 
       FIG.  13    is a cross-sectional view illustrating a configuration example of the display device according to the first modified example of the third embodiment. Referring to  FIG.  13   , the display device  1   j  according to the first modified example has a configuration in which the reflector is added to the configuration of the display device  1   d  according to the first modified example of the second embodiment. At the same time, in the display device  1   j , in addition to the configuration of the display device  1   i  according to the third embodiment described above, an adhesive layer  123  is formed between the protection film  109  and the reflector  119 . 
     In the above-described embodiment, the display device  1   i  has a configuration in which the reflector  119  is formed on the protection film  109  similarly to the display device  1   c  according to the second embodiment. Here, depending on a material of the protection film  109  and a material of the reflector  119 , it is concerned that the adhesion between the protection film  109  and the reflector  119  may decrease. Therefore, in the third embodiment, when the reflector  119  is formed on the protection film  109  as in the first modified example, the adhesive layer  123  may be formed between the protection film  109  and the reflector  119 . Since the adhesive layer  123  is formed, it is possible to connect the protection film  109  and the reflector  119  more suitably, and thus a more stable display device  1   j  can be obtained. 
       FIG.  14    is a cross-sectional view illustrating a configuration example of the display device according to the second modified example of the third embodiment. Referring to  FIG.  14   , the display device  1   k  according to the second modified example has a configuration in which the reflector is added to the configuration of the display device  1   e  according to the second modified example of the second embodiment. At the same time, in the display device  1   k , in addition to the configuration of the display device  1   i  in accordance with the above third embodiment, the reflector  119  is formed above the CF layer  113 . As in the second modified example, in the third embodiment, the arrangement position of the reflector  119  in the stacking direction is not limited, and the reflector  119  may be formed at an arbitrary position in the stacking direction as long as the reflector  119  is formed above the light emitting element  103 . 
       FIGS.  15  to  17    are cross-sectional views illustrating configuration examples of display devices according to third to the fifth modified examples of the third embodiment, respectively. Referring to  FIGS.  15  to  17   , the display devices  1   l ,  1   m , and  1   n  according to the third to fifth modified examples have configurations in which the reflector is added to the configurations of the display devices  1   f ,  1   g , and  1   h  according to the third to fifth modified examples of the second embodiment. 
     Here, the display devices  1   i ,  1   j , and  1   k  according to the third embodiment and the first and second modified examples thereof are the display devices of the OCCF scheme. On the other hand, the display devices  1   l ,  1   m , and  1   n  according to the third to fifth modified examples illustrated in  FIGS.  15  to  17    are the display devices of the facing CF scheme. As described above, the display device according to the third embodiment may be a display device of any of the OCCF scheme and the facing CF scheme. 
     4. With Regard to Amount of Misalignment of CF 
     As described above, in the second and third embodiments, the configuration in which the center of the luminescence surface of the light emitting element  103  in the horizontal surface and the center of the CF  113   a  are shifted from each other by a predetermined amount of misalignment L is provided. Here, a method for setting the amount of misalignment L will be described. In the second and third embodiments, the amount of misalignment L of the CF  113   a  in a pixel is set in accordance with the viewing angle required of the pixel. In the following, with a focus on one pixel, a method for setting the amount of misalignment L of the CF  113   a  in the pixel in a case where the viewing angle required of the pixel is θ 0  is described with reference to  FIG.  18    to  FIG.  21   .  FIG.  18    to  FIG.  21    are diagrams for describing a method for setting the amount of misalignment L of the CF  113   a . Each of  FIG.  18    to  FIG.  21    simulatively shows the luminescence section  127  of one light emitting element  103 , one CF  113   a  provided to correspond to the light emitting element  103  (in the illustrated example, a CF  113 R), and the display surface  201  of the display device according to the second and third embodiments. 
     As shown in  FIG.  18    to  FIG.  21   , a case where the viewing angle of the focused-on pixel is θ 0  means a case where, when emission light from the luminescence section  127  passes through the CF  113 R and other medium layers (the first member  107 , the protection film  109 , the planarizing film  111 , etc. described with reference to  FIG.  4    or the like) and is emitted from the display surface  201 , light is emitted in a direction at an angle of θ 0  from the direction perpendicular to the display surface  201 . Here, it is assumed that the medium layers other than the CF  113 R contain a uniform material, for the sake of simplicity; if the refractive index of this material is denoted by n 1 , the refractive index of the CF  113 R is denoted by n 2 , and the refractive index of an air layer on the outside of the display surface  201  is denoted by n 0 , the emission angle θ 1  of emission light from the luminescence section  127  (the angle of emission light with respect to the direction perpendicular to the luminescence surface of the luminescence section  127 ) when emission light from the display surface  201  has an angle of θ 0  can be expressed by Mathematical Formula (1) below from the law of refraction.

     In other words, if light emitted from the luminescence section  127  at an emission angle of θ 1  passes through the CF  113 R and the other medium layers and travels, light with a viewing angle of θ 0  is emitted from the display surface  101 . Therefore, the amount of misalignment L of the CF  113 R for obtaining light with a viewing angle of θ 0  on the display surface  101  may be set as a such a value that light emitted from the luminescence section  127  at an emission angle of θ 1  passes through the CF  113 R and the other medium layers. Here, medium layers such as the first member  107  and the protection film  109  exist immediately above the luminescence section  127  in the display device according to the second and third embodiments as described with reference to  FIG.  4   , and emission light from the luminescence section  127  necessarily passes through these medium layers because of the structure; hence, there is no need to consider conditions for emission light from the luminescence section  127  to pass through these medium layers. Therefore, in the end, the amount of misalignment L of the CF  113 R for obtaining light with a viewing angle of θ 0  on the display surface  201  may be set as such a value that emission light with an emission angle of θ 1  from the luminescence section  127  passes through the CF  113 R. Thus, in the second and third embodiments, the amount of misalignment L of the CF  113 R is set as such a value that emission light with an emission angle of θ 1  from the luminescence section  127  is incident on the lower surface of the CF  113 R. 
     First, it is assumed that light is emitted from one point of the center of the luminescence surface of the luminescence section  127 , for the sake of simplicity; and the range of the amount of misalignment L of the CF  113 R in this case is set. In this event, the case where the value of the amount of misalignment L of the CF  113 R is largest is a case where emission light from the center of the luminescence surface of the luminescence section  127  is incident on an end of the lower surface of the CF  113 R on a side near to the luminescence section  127 .  FIG.  18    shows the positional relationship between the luminescence section  127  and the CF  113 R and the locus of a light beam in such a case where emission light from the center of the luminescence surface of the luminescence section  127  is incident on an end of the lower surface of the CF  113 R on a side near to the luminescence section  127  (in the illustrated example, the left end). When the luminescence section  127  and the CF  113 R are in the positional relationship shown in  FIG.  18   , the amount of misalignment L of the CF  113 R can be expressed by Mathematical Formula (2) below from geometric consideration.

     On the other hand, in a case where it is assumed that light is emitted from one point of the center of the luminescence surface of the luminescence section  127 , the case where the value of the amount of misalignment L of the CF  113 R is smallest is a case where emission light from the center of the luminescence surface of the luminescence section  127  is incident on an end of the lower surface of the CF  113 R on a side far from the luminescence section  127 .  FIG.  19    shows the positional relationship between the luminescence section  127  and the CF  113 R and the locus of a light beam in such a case where emission light from the center of the luminescence surface of the luminescence section  127  is incident on an end of the lower surface of the CF  113 R on a side far from the luminescence section  127  (in the illustrated example, the right end).

     However, in practice, light may be emitted from the luminescence section  127  also from areas other than the center of the luminescence surface of the luminescence section  127 . Thus, next, the range of the amount of misalignment L of the CF  113 R is set more finely by further taking into account luminescence positions in the luminescence surface of the luminescence section  127 . In a case where luminescence positions in the luminescence surface of the luminescence section  127  are taken into account, the case where the value of the amount of misalignment L of the CF  113 R is largest is a case where emission light from a luminescence position of the luminescence surface of the luminescence section  127  nearest to the CF  113 R is incident on the lower surface of the CF  113 R.  FIG.  20    shows the positional relationship between the luminescence section  127  and the CF  113 R and the locus of a light beam in such a case where emission light from a luminescence position of the luminescence surface of the luminescence section  127  nearest to the CF  113 R (in the illustrated example, the right end) is incident on the lower surface of the CF  113 R. Note that  FIG.  20    shows, as an example, the positional relationship between the luminescence section  127  and the CF  113 R and the locus of a light beam in a case where emission light from the luminescence section  127  is incident on an end of the lower surface of the CF  113 R on a side near to the luminescence section  127  (in the illustrated example, the left end), like in the case shown in  FIG.  8   . When the luminescence section  127  and the CF  113 R are in the positional relationship shown in  FIG.  20   , the amount of misalignment L of the CF  113 R can be expressed by Mathematical Formula (5) below from geometric consideration.

     On the other hand, in a case where luminescence positions in the luminescence surface of the luminescence section  127  are taken into account, the case where the value of the amount of misalignment L of the CF  113 R is smallest is a case where emission light from a luminescence position of the luminescence surface of the luminescence section  127  farthest from the CF  113 R is incident on the lower surface of the CF  113 R.  FIG.  21    shows the positional relationship between the luminescence section  127  and the CF  113 R and the locus of a light beam in such a case where emission light from a luminescence position of the luminescence surface of the luminescence section  127  farthest from the CF  113 R (in the illustrated example, the left end) is incident on the lower surface of the CF  113 R. Note that  FIG.  21    shows, as an example, the positional relationship between the luminescence section  127  and the CF  113 R and the locus of a light beam in a case where emission light from the luminescence section  127  is incident on an end of the lower surface of the CF  113 R on a side near to the luminescence section  127  (in the illustrated example, the left end), like in the case shown in  FIG.  18   . When the luminescence section  127  and the CF  113 R are in the positional relationship shown in  FIG.  21   , the amount of misalignment L of the CF  113 R can be expressed by Mathematical Formula (6) below from geometric consideration.

     In  FIG.  20    and  FIG.  21    above, the case shown in  FIG.  18    is envisaged, and the amount of misalignment L of the CF  113 R in a case where emission light from the luminescence section  127  is incident on an end of the lower surface of the CF  113 R on a side near to the luminescence section  127  is calculated; this similarly applies to the case shown in  FIG.  19    where emission light from the luminescence section  127  is incident on an end of the lower surface of the CF  113 R on a side far from the luminescence section  127 . Therefore, in the end, the range of values that the amount of misalignment L of the CF  113 R can take in order to obtain a viewing angle of θ 0  for emission light from the display surface  201  can be expressed by Mathematical Formula (7) below. In other words, if the amount of misalignment L of the CF  113 R is set so as to satisfy Mathematical Formula (7) below, a viewing angle of θ 0  can be obtained for emission light from the display surface  201 .

     Hereinabove, a method for setting the amount of misalignment L of the CF  113 R is described. Note that, in the above example, medium layers are treated as a uniform material and the range that the amount of misalignment L of the CF  113   a  can take is calculated on the assumption that the refractive index of this material is n 2 , for the sake of simplicity; in a case where it is attempted to find the range of the amount of misalignment L more strictly, the structure of an actual display device like that shown in  FIG.  4    or the like may be envisaged, and a similar calculation may be performed while the refractive index of each layer is taken into account. 
     5. Modification Examples 
     Some additional modification examples of each of the embodiments described hereinabove will now be described. 
     5-1. Method of Causing Relative Misalignment Between Light Emitting Element and CF 
     In the second and third embodiments described above, in order to cause the relative misalignment between the light emitting element  103  and the CF  113   a , the region in which the CF  133   a  is not formed in the CF layer  113  is formed as transition region  301  in which the amount of misalignment L and the misalignment direction of CF  113   a  change as described above with reference to  FIG.  6   . Here, in the second and third embodiments, the method of causing the relative misalignment between the light emitting element  103  and the CF  113   a  is not limited to the above method, and other methods may be used. 
     A modified example in which the relative misalignment between light emitting element  103  and CF  113   a  is caused by another method will be described with reference to  FIG.  22   .  FIG.  22    is a diagram for explaining another method of causing the relative misalignment between the light emitting element  103  and the CF  113   a . Further, in the present modified example, a case in which the method of causing the relative misalignment between the light emitting element  103  and the CF  113   a  is different from that of the display device  1   i  according to the third embodiment illustrated in  FIG.  12    will be described as an example. In other words, the display device according to the present modified example has a configuration similar to that of the display device  1   i  except that the method of causing the relative misalignment between the light emitting element  103  and the CF  113   a  is different. In  FIG.  22   , a cross section of a display device  1   p  according to the present modified example is simplified, and only a first substrate  101 , a light emitting element  103 , a pixel defining film  105   a , and a CF layer  113  are illustrated. 
     In the present modification examples, like in the second and third embodiments, the inside of the display surface of the display device  1   p  is divided into a plurality of regions, and the amount of misalignment L and the misalignment direction may be set for each region in accordance with the position in the display surface of the region.  FIG.  22    shows, as an example, region  303  in which the amount of displacement L of the CF  113   a= 0, region  305  that is adjacent to region  303  and in which the amount of displacement L of the CF  113   a  is a prescribed value that is not zero, and a transition region  307  provided between region  303  and region  305 , similarly to  FIG.  6   . As illustrated, in the present modification example, the transition region  307  is formed as a region in which the pitch with which light emitting elements  103  are arranged (that is, the pixel spacing) is narrower than a normal pitch of another region. Further, in the transition region  307 , an arrangement pitch is adjusted such that the arrangement pitch of the light emitting element  103  is reduced on the misalignment side. Thereby, in region  305 , the center of the CF  113   a  is placed to be shifted in the horizontal plane from the center of the luminescence surface of the luminescence section  127  by an amount of misalignment L&gt;0 in the direction in which the arrangement pitch of the light emitting element  103  is reduced. Also between not-shown other regions, the amount of misalignment L and/or the misalignment direction can be changed between regions by providing a similar transition region  307 . 
     Further, another modified example of causing the relative misalignment between light emitting element  103  and CF  113   a  will be described with reference to  FIG.  23   .  FIG.  23    is a diagram for describing still another method of causing the relative misalignment between the light emitting element  103  and the CF  113   a .  FIG.  23    schematically illustrates a state in which a configuration near the boundary between two regions which are different in the amount of misalignment L of the CF  113   a  of the CF layer  113  of the display device  1   q  according to the present modified example is viewed from above. Further, the display device  1   q  according to the present modified example has a configuration similar to those of the display devices  1   c  and  1   i  according to the second and third embodiments except that the method of causing the relative misalignment between the light emitting element  103  and the CF  113   a  is different. 
     In the present modified example, similarly, the display surface of the display device  1   q  is divided into a plurality of regions, and the amount of misalignment L and misalignment direction can be set for each region in accordance with a position of each region in the display surface.  FIG.  23    shows, like in  FIG.  22   , as an example, region  303  where the amount of displacement L of the CF  113   a= 0, region  305  that is adjacent to region  303  and in which the amount of displacement L of the CF  113   a  is a prescribed value that is not zero, and a transition region  301  provided between region  303  and region  305 . As illustrated, the transition region  301  is formed as a region in which the area of the CF  113   a  is larger than the area of a normal CF  113   a  in another region. Further, the CF  113   a  located in the transition region  301  is formed such that the area of the CF  113   a  is increased on the misalignment side. Thereby, in region  305 , the center of the CF  113   a  is placed to be shifted in the horizontal plane from the center of the luminescence surface of the light emitting element  103  by an amount of misalignment L&gt;0 in the direction in which the area of the CF  113   a  located in the transition region  301  is increased. Also between not-shown other regions, the amount of misalignment L and/or the misalignment direction can be changed between regions by providing a similar transition region  301 . 
     Note that, also in any of the modification examples described above, the amount of misalignment L and the misalignment direction may be set not on a region basis but on a pixel basis, and the amount of misalignment L and the misalignment direction may be changed in a continuous manner between pixels in accordance with the position in the display surface  201  of the pixel, like in the second and third embodiments described above. Further, the misalignment direction of the CF  113   a  may be only one of the horizontal direction and the vertical direction of the display surface  201 , or may be a two-dimensional arbitrary direction in the horizontal plane. 
     5-2. Other Methods for Setting Amount of Misalignment L of CF 
     As described in (4. With regard to amount of misalignment of CF) above, in the second and third embodiments described above, the amount of misalignment L of the CF  113   a  is set by prescribing conditions where emission light from the luminescence section  127  is incident on the lower surface of the CF  113 R. However, the second and third embodiments are not limited to this example. For example, it is presumed that, depending on the characteristics of emission light from the luminescence section  127 , the characteristics of the CF  113   a , etc., color conversion will be performed appropriately and light of desired characteristics can be emitted from the display surface  201  even in a case where emission light from the luminescence section  127  is incident on the side surface of the CF  113   a . Thus, the amount of misalignment L of the CF  113   a  may be set taking into account also a case where emission light from the luminescence section  127  is incident on the side surface of the CF  113   a.    
     Such a modification example in which the amount of misalignment L of the CF  113   a  is set taking into account also a case where emission light from the luminescence section  127  is incident on the side surface of the CF  113   a  will now be described with reference to  FIG.  24   .  FIG.  24    is a diagram for describing a method for setting the amount of misalignment L of the CF  113   a  taking into account also a case where emission light from the luminescence section  127  is incident on the side surface of the CF  113   a . Similarly to  FIG.  18    to  FIG.  21   ,  FIG.  24    simulatively shows the luminescence section  127  of one light emitting element  10  provided in a display device according to the present modification example, one CF  113   a  provided to correspond to the light emitting element  10  (in the illustrated example, a CF  113 R), and the display surface  201  of the display device. Further, medium layers are treated as layers containing a uniform material with a refractive index of n 2 . 
     Herein, it is assumed that light is emitted from one point of the center of the luminescence surface of the luminescence section  127 , for the sake of simplicity. In this event, in a case where emission light from the luminescence section  127  is incident on the side surface of the CF  113   a , the case where the value of the amount of displacement L of the CF  113 R is largest is a case where emission light from the luminescence section  127  is incident on the vicinity of the upper end of the side surface of the CF  113   a . Herein, a case where emission light from the luminescence section  127  is incident on the upper end of the side surface of the CF  113   a  is assumed for the sake of simplicity.  FIG.  24    shows the positional relationship between the luminescence section  127  and the CF  113 R and the locus of a light beam in such a case where emission light from the luminescence section  127  is incident on the upper end of the side surface of the CF  113 R. When the luminescence section  127  and the CF  113 R are in the positional relationship shown in  FIG.  24   , the amount of misalignment L of the CF  113 R can be expressed by Mathematical Formula (8) below from geometric consideration.

     Here, the thickness of the CF  113 R is denoted by h 2 ; within the distance d in the horizontal plane from the luminescence position in the luminescence section  127  to the position where emission light is incident on the CF  113 R, the length of a portion corresponding to the distance gi in the stacking direction from the surface of the luminescence section  127  to the lower surface of the CF  113 R is denoted by d 1 ; and within the distance d, the length of a portion corresponding to the thickness h 2  of the CF  113 R is denoted by w p . 
     Thus, the upper limit value of the range that the amount of displacement L of the CF  113 R can take is made larger by taking into account also a case where emission light from the luminescence section  127  is incident on the side surface of the CF  113   a . In  FIG.  24   , it is assumed that light is emitted from one point of the center of the luminescence surface of the luminescence section  127 ; however, if also a case where light is emitted from other parts in the luminescence surface is taken into account like in the consideration in (4. With regard to amount of misalignment of CF) above, the range that the amount of displacement L of the CF  113 R can take can be expressed by Mathematical Formula (9) below, in the end. In other words, in the present modification example, if the amount of misalignment L of the CF  113 R is set so as to satisfy Mathematical Formula (9) below, a viewing angle of θ 0  can be obtained for emission light from the display surface  201 . Note that, in practice, if emission light from the luminescence section  127  is not incident on “the vicinity of the upper end” of the side surface of the CF  113   a , the emission light does not pass through the CF  113   a  and color conversion is not performed appropriately; hence, in Mathematical Formula (9) below, a case where emission light from the luminescence section  127  is incident on “the upper end” of the side surface of the CF  113   a , that is, a case where L is equal to the upper limit value is excluded.

     6. Specific Configuration Example of Display Device 
     More specific configuration examples of the display devices according to the respective embodiments and the respective modified examples described above will be described. Here, a specific configuration example of the display device  1   i  according to the third embodiment will be described as an example with reference to  FIG.  25   . Here, specific configurations of the display device according to another embodiment and the display device according to each modified example of each embodiment may be similar to that of the display device illustrated in  FIG.  25    to be described below except for the difference from the display device  1   i  according to the third embodiment described above. 
       FIG.  25    is a cross-sectional view illustrating a specific configuration example of the display device  1   i  according to the third embodiment.  FIG.  25    illustrates a partial sectional view of the display device  1   i.    
     Referring to  FIG.  25   , a display device  1   i  according to the third embodiment includes, on a first substrate  11 , a plurality of light emitting elements  10  each of which includes an OLED and emits white light, and a CF layer  33  that is provided on the light emitting elements  10  and in which CFs of some colors are formed to correspond to the light emitting elements  10 . Further, a second substrate  34  containing a material transparent to the light from the light emitting element  10  is placed on the CF layer  33 . A first substrate  11 , a light emitting element  10 , a CF layer  33 , and a second substrate  34  correspond to the first substrate  101 , the light emitting element  103 , the CF layer  113 , and the second substrate  117 , respectively. 
     Further, on the first substrate  11 , TFTs  15  for driving the light emitting elements  10  are provided to correspond to the light emitting elements  10 . An arbitrary light emitting element  10  is selectively driven by the TFT  15 , then light from the driven light emitting element  10  passes through the corresponding CF, and the color of the light is converted appropriately and the converted light is emitted from the upper side via the second substrate  34 ; thereby, desired images, characters, etc. are displayed. 
     (First Substrate and Second Substrate) 
     In the illustrated configuration example, the first substrate  11  includes a silicon substrate. Further, the second substrate  34  contains quartz glass. However, the third embodiment is not limited to this example, and various publicly-known materials may be used as the first substrate  11  and the second substrate  34 . For example, each of the first substrate  11  and the second substrate  34  may include a high strain point glass substrate, a soda-lime glass (a mixture of Na 2 O, CaO, and SiO 2 ) substrate, a borosilicate glass (a mixture of Na 2 O, B 2 O 3 , and SiO 2 ) substrate, a forsterite (Mg 2 SiO 4 ) substrate, a lead glass (a mixture of Na 2 O, PbO, and SiO 2 ) substrate, various glass substrates in which an insulating film is formed on a surface, a quartz substrate, a quartz substrate in which an insulating film is formed on a surface, a silicon substrate in which an insulating film is formed on a surface, or an organic polymer substrate (for example, polymethyl methacrylate (PMMA), polyvinyl alcohol (PVA), polyvinylphenol (PVP), a polyether sulfone (PES), a polyimide, a polycarbonate, polyethylene terephthalate (PET), or the like). The materials contained in the first substrate  11  and the second substrate  34  may be the same, or may be different. However, since the display device  1   i  is of the top emission type, the second substrate  34  preferably contains a material with a high transmittance that can transmit the light from the light emitting element  10  favorably. 
     (Light Emitting Element and Second Member) 
     The light emitting element  10  includes a first electrode  21 , an organic layer  23  provided on the first electrode  21 , and a second electrode  22  formed on the organic layer  23 . More specifically, a second member  52  in which openings  25  are provided so as to expose at least parts of the first electrode  21  is stacked on the first electrode  21 , and the organic layer  23  is provided on portions of the first electrode  21  that are exposed at the bottoms of the openings  25 . That is, the light emitting element  10  has a configuration in which the first electrode  21 , the organic layer  23 , and the second electrode  22  are stacked in this order in the opening  25  of the second member  52 . This stacked structure functions as a luminescence section  24  of each pixel. That is, a portion of the light emitting element  10  falling under the opening  25  of the second member  52  serves as a luminescence surface. Further, the second member  52  functions as a pixel defining film that is provided between pixels and partitions the area of the pixel. The second member  52  corresponds to the pixel defining film  105   a  described above. 
     The organic layer  23  includes a luminescence layer containing an organic luminescent material, and can emit white light. The specific configuration of the organic layer  23  is not limited, and may be various publicly-known configurations. For example, the organic layer  23  may have a stacked structure of a hole transport layer, a luminescence layer, and an electronic transport layer, a stacked structure of a hole transport layer and a luminescence layer that serves also as an electronic transport layer, a stacked structure of a hole injection layer, a hole transport layer, a luminescence layer, an electronic transport layer, and an electron injection layer, or the like. Further, in a case where each of these stacked structures or the like is used as a “tandem unit,” the organic layer  23  may have a tandem structure of two stages in which a first tandem unit, a connection layer, and a second tandem unit are stacked. Alternatively, the organic layer  23  may have a tandem structure of three or more stages in which three or more tandem units are stacked. In a case where the organic layer  23  includes a plurality of tandem units, an organic layer  23  that emits white light as a whole can be obtained by assigning red, green, and blue to the luminescent colors of the luminescence layers of the tandem units. 
     In the illustrated configuration example, the organic layer  23  is formed by depositing an organic material by vacuum vapor deposition. However, the third embodiment is not limited to this example, and the organic layer  23  may be formed by various publicly-known methods. For example, as the method for forming the organic layer  23 , physical vapor deposition methods (PVD methods) such as the vacuum vapor deposition method, printing methods such as the screen printing method and the inkjet printing method, a laser transfer method in which a stacked structure of a laser absorbing layer and an organic layer formed on a substrate for transfer is irradiated with laser light to separate the organic layer on the laser absorbing layer and the organic layer is transferred, various application methods, etc. may be used. 
     The first electrode  21  functions as an anode. Since the display device  1   i  is of the top emission type, the first electrode  21  contains a material capable of reflecting the light from the organic layer  23 . In the illustrated configuration example, the first electrode  21  contains an alloy of aluminum and neodymium (Al—Nd alloy). Further, the film thickness of the first electrode  21  is approximately 0.1 μm to 1 μm, for example. However, the third embodiment is not limited to this example, and the first electrode  21  may contain various publicly-known materials used as the material of an electrode on the light reflection side that functions as an anode in a common organic EL display. Further, the film thickness of the first electrode  21  is not limited to the above example either, and the first electrode  21  may be formed in film thickness ranges commonly employed in organic EL displays, as appropriate. 
     For example, the first electrode  21  may contain a metal with a high work function, such as platinum (Pt), gold (Au), silver (Ag), chromium (Cr), tungsten (W), nickel (Ni), copper (Cu), iron (Fe), cobalt (Co), or tantalum (Ta), or an alloy with a high work function (for example, a Ag—Pd—Cu alloy containing silver as a main component and containing 0.3 mass % to 1 mass % of palladium (Pd) and 0.3 mass % to 1 mass % of copper, an Al—Nd alloy, or the like). Alternatively, the first electrode  21  may contain an electrically conductive material having a small work function value and a high light reflectance, such as aluminum or an alloy containing aluminum. In this case, it is preferable to improve hole injection properties by providing an appropriate hole injection layer on the first electrode  21 , or the like. Alternatively, the first electrode  21  may have a structure in which a transparent electrically conductive material excellent in hole injection characteristics, such as an oxide of indium and tin (ITO) or an oxide of indium and zinc (IZO), is stacked on a reflective film with high light reflectivity such as a dielectric multiple-layer film or aluminum. 
     The second electrode  22  functions as a cathode. Since the display device  1   i  is of the top emission type, the second electrode  22  contains a material capable of transmitting the light from the organic layer  23 . In the illustrated configuration example, the second electrode  22  contains an alloy of magnesium and silver (Mg—Ag alloy). Further, the film thickness of the second electrode  22  is approximately 10 nm, for example. However, the third embodiment is not limited to this example, and the second electrode  22  may contain various publicly-known materials used as the material of an electrode on the light transmission side that functions as a cathode in a common organic EL display. Further, the film thickness of the second electrode  22  is not limited to the above example either, and the second electrode  22  may be formed in film thickness ranges commonly employed in organic EL displays, as appropriate. 
     For example, the second electrode  22  may contain aluminum, silver, magnesium, calcium (Ca), sodium (Na), strontium (Sr), an alloy of an alkali metal and silver, an alloy of an alkaline earth metal and silver (for example, an alloy of magnesium and silver (Mg—Ag alloy)), an alloy of magnesium and calcium (Mg—Ca alloy), an alloy of aluminum and lithium (Al—Li alloy), or the like. In a case where each of these materials is used in a single layer, the film thickness of the second electrode  22  is approximately 4 nm to 50 nm, for example. Alternatively, the second electrode  22  may have a structure in which a layer of any of the materials described above and a transparent electrode containing, for example, ITO or IZO (with a thickness of, for example, approximately 30 nm to 1 μm) are stacked from the organic layer  23  side. In a case where such a stacked structure is used, the thickness of the layer of any of the materials described above may be as thin as approximately 1 nm to 4 nm, for example. Alternatively, the second electrode  22  may include only a transparent electrode. Alternatively, the second electrode  22  may be provided with a bus electrode (auxiliary electrode) containing a low resistance material, such as aluminum, an aluminum alloy, silver, a silver alloy, copper, a copper alloy, gold, or a gold alloy, to reduce the resistance of the second electrode  22  as a whole. 
     In the illustrated configuration example, each of the first electrode  21  and the second electrode  22  is formed by forming a material as a film with a prescribed thickness by the vacuum vapor deposition method and then patterning the film by the etching method. However, the third embodiment is not limited to this example, and the first electrode  21  and the second electrode  22  may be formed by various publicly-known methods. Examples of the method for forming the first electrode  21  and the second electrode  22  include vapor deposition methods including the electron beam vapor deposition method, the hot filament vapor deposition method, and the vacuum vapor deposition method, the sputtering method, the chemical vapor deposition method (CVD method), the metal organic chemical vapor deposition method (MOCVD method), a combination of the ion plating method and the etching method, various printing methods (for example, the screen printing method, the inkjet printing method, the metal mask printing method, etc.), plating methods (the electroplating method, the electroless plating method, etc.), the lift-off method, the laser ablation method, the sol-gel method, etc. 
     The second member  52  is formed by forming SiO 2  as a film with a prescribed film thickness by the CVD method and then patterning the SiO 2  film using photolithography technology and etching technology. However, the material of the second member  52  is not limited to this example, and various materials having insulating properties may be used as the material of the second member  52 . Examples of the material contained in the second member  52  include SiO 2 , MgF, LiF, a polyimide resin, an acrylic resin, a fluorine resin, a silicone resin, a fluorine-based polymer, a silicone-based polymer, etc. However, as described later, the second member  52  contains a material having a lower refractive index than the material of a first member  51 . 
     (Configuration of Parts Below Light Emitting Element) 
     On the first substrate  11 , the first electrode  21  included in the light emitting element  10  is provided on an interlayer insulating layer  16  containing SiON. Then, the interlayer insulating layer  16  covers a light emitting element driving section formed on the first substrate  11 . 
     The light emitting element driving section includes a plurality of TFTs  15 . In the illustrated example, one TFT  15  is provided for one light emitting element  10 . The TFT  15  includes a gate electrode  12  formed on the first substrate  11 , a gate insulating film  13  formed on the first substrate  11  and the gate electrode  12 , and a semiconductor layer  14  formed on the gate insulating film  13 . A region of the semiconductor layer  14  located immediately above the gate electrode  12  functions as a channel region  14 A, and regions located so as to sandwich the channel region  14 A function as source/drain regions  14 B. Note that, although in the illustrated example the TFT  15  is of a back gate type, the third embodiment is not limited to this example, and the TFT  15  may be of a bottom gate type. 
     An interlayer insulating layer  16  including two layers (a lower layer interlayer insulating layer  16 A and an upper layer interlayer insulating layer  16 B) is stacked on the semiconductor layer  14  by the CVD method. In this event, after the lower layer interlayer insulating layer  16 A is stacked, contact holes  17  are provided in portions of the lower layer interlayer insulating layer  16 A corresponding to the source/drain regions  14 B so as to expose the source/drain regions  14 B, by using photolithography technology and etching technology, for example, and an interconnection  18  containing aluminum is formed so as to fill the contact hole  17 . The interconnections  18  are formed by combining the vacuum vapor deposition method and the etching method, for example. After that, the upper layer interlayer insulating layer  16 B is stacked. 
     In a portion of the upper layer interlayer insulating layer  16 B where the interconnection  18  is provided, a contact hole  19  is provided so as to expose the interconnection  18 , by using photolithography technology and etching technology, for example. Then, when forming the first electrode  21  of the light emitting element  10 , the first electrode  21  is formed so as to be in contact with the interconnection  18  via the contact hole  19 . Thus, the first electrode  21  of the light emitting element  10  is electrically connected to a source/drain region  14 B of the TET  15  via the interconnection  18 . The gate electrode  12  of the TFT  15  is connected to a scanning circuit (not shown). Each TFT  15  is driven by a current being applied to the TFT  15  from the scanning circuit at an appropriate timing, and each light emitting element  10  emits light so that desired images, characters, etc. are displayed as a whole. Various publicly-known methods may be used as the method for driving the TFT  15  to obtain appropriate display (that is, the method for driving the display device  1   i ), and hence a detailed description is omitted herein. 
     Note that, although in the above example the interlayer insulating layer  16  contains SiON, the third embodiment is not limited to this example. The interlayer insulating layer  16  may contain various publicly-known materials that can be used as an interlayer insulating layer in a common organic EL display. For example, as the material contained in the interlayer insulating layer  16 , SiO 2 -based materials (for example, SiO 2 , BPSG, PSG, BSG, AsSG, PbSG, SiON, spin-on glass (SOG), low melting point glass, a glass paste, and the like), SiN-based materials, and insulating resins (for example, a polyimide resin, a novolac-based resin, an acrylic-based resin, polybenzoxazole, and the like) may be used singly or in combination, as appropriate. Further, the method for forming the interlayer insulating layer  16  is not limited to the above example either, and publicly-known methods such as the CVD method, the application method, the sputtering method, and various printing methods may be used for the formation of the interlayer insulating layer  16 . Furthermore, although in the above example the interconnection  18  is formed by forming aluminum as a film and patterning the film by the vacuum vapor deposition method and the etching method, the third embodiment is not limited to this example. The interconnection  18  may be formed by forming, as a film, any of various materials that are used as an interconnection in a common organic EL display and patterning the film by various methods. 
     (Configuration of Parts Above Light Emitting Element  10 ) 
     The opening  25  provided in the second member  52  of the light emitting element  10  is formed so as to have a tapered shape in which the side wall of the opening  25  is inclined such that the opening area increases with proximity to the bottom. Then, a first member  51  is put in the opening  25 . That is, the first member  51  is a layer that is provided immediately above the luminescence surface of the light emitting element  10  and that propagates emission light from the light emitting element upward. Further, by forming the opening  25  of the second member  52  in the above manner, a cross-sectional shape in the stacking direction of the first member  51  (that is, the illustrated cross-sectional shape) has a substantially trapezoidal shape, and thus the first member  51  has a truncated conical or pyramidal shape in which the bottom surface faces up. The first member  51  corresponds to the first member  107  described above. 
     The first member  51  is formed by forming Si 1-x N x  as a film by the vacuum vapor deposition method so as to fill the opening  25 , and then planarizing the surface of the Si 1-x N x  film by the chemical mechanical polishing method (CMP method) or the like. However, the material of the first member  51  is not limited to this example, and various materials having insulating properties may be used as the material of the first member  51 . Examples of the material contained in the first member  51  include Si 1-x N x , ITO, IZO, TiO 2 , Nb 2 O 5 , a bromine-containing polymer, a sulfur-containing polymer, a titanium-containing polymer, a zirconium-containing polymer, etc. The method for forming the first member  51  is not limited to this example either, and various publicly-known methods may be used as the method for forming the first member  51 . 
     However, in the third embodiment, as described above, the materials of the first member  51  and the second member  52  are selected such that the refractive index n 1  of the first member  51  and the refractive index n 2  of the second member  52  satisfy the relation of n 1 &gt;n 2 . By selecting the materials of the first member  51  and the second member  52  such that the refractive indices satisfy the relation mentioned above, at least a part of the light that has propagated through the first member  51  is reflected at a surface of the second member  52  facing the first member  51 . More specifically, the organic layer  23  and the second electrode  22  of the light emitting element  10  are formed between the first member  51  and the second member  52 , and therefore at least a part of the light that has propagated through the first member  51  is reflected at the interface between the second member  52  and the organic layer  23 . That is, the surface of the second member  52  facing the first member  51  functions as a reflector  53 . 
     In the third embodiment, the first member  51  is provided immediately above the luminescence surface of the light emitting element  10 , as mentioned above. Then, the first member  51  has a truncated conical or pyramidal shape in which the bottom surface faces up, and therefore light emitted from the luminescence surface of the light emitting element  10  is reflected upward, which is the light emission direction, by the interface between the first member  51  and the second member  52 , that is, the reflector  53 . Thus, according to the third embodiment, the efficiency of extracting emission light from the light emitting element  10  can be improved by providing the reflector  53 , and the luminance as the entire display device  1   i  can be improved. 
     Note that an investigation by the present inventors shows that, to improve the efficiency of extracting emission light from the light emitting element  10  more favorably, it is preferable that the refractive indices of the first member  51  and the second member  52  satisfy the relation of n 1 −n 2 ≥0.20. It is more preferable that the refractive indices of the first member  51  and the second member  52  satisfy the relation of n 1 −n 2 ≥0.30. Furthermore, to further improve the efficiency of extracting emission light from the light emitting element  10 , it is preferable that the shape of the first member  51  satisfy the relations of 0.5≤R 1 /R 2 ≤0.8 and 0.5≤H/R 1 ≤0.8. Here, R 1  represents the diameter of the light incidence surface of the first member  51  (that is, a surface facing down in the stacking direction and facing the luminescence surface of the light emitting element  10 ), R 2  represents the diameter of the light emitting surface of the first member  51  (that is, a surface facing up in the stacking direction), and H represents the distance between the bottom surface and the upper surface (the height in the stacking direction) in a case where the first member  51  is regarded as a truncated cone or pyramid. 
     A protection film  31  is stacked on a planarized first member  51 . The protection film  31  corresponds to the protection film  109  described above. For example, the protection film  31  is formed by depositing Si 1-y N y  at a predetermined thickness (about 3.0 um) through a vacuum evaporation technique. Here, a material and a film thickness of the protection film  31  are not limited to this example, and the protection film  31  may be appropriately formed to have a film thickness commonly employed in an organic EL display using various publicly-known materials used as a protection film of a common organic EL display. 
     A reflector  119  is formed on the protection film  31 , corresponding to each pixel. The reflector  119  has a structure in which the recursive structure of the prism type is formed toward the lower surface serving as the reflective surface. The recursive structure of the prism type can be realized, for example, by arranging right triangular pyramids having a substantially equilateral triangle shape at a plan view consecutively. The reflector  119  having the recursive structure of the prism type can be formed, for example, by applying a technique of forming an opening in a film by etching so that a side wall has a tapered shape in a semiconductor process and processing a film (for example, a metallic film) made of a material having an appropriate reflectance in a prism shape using a photolithography technique and an etching technique. 
     Here, the third embodiment is not limited to this example, and the reflector  119  may have another configuration or may be formed by another processing technique. For example, the reflector  119  having the recursive structure of the prism type may be formed by manufacturing a master on which a structure obtained by inverting the prism shape is formed on a surface and transferring a shape of a surface of the master onto a surface of a film made of a material having an appropriate reflectance (for example, a metallic film). 
     Alternatively, for example, the reflector  119  may have the recursive structure of the bead type instead of the prism type. The reflector  119  having the recursive structure of the bead type can be formed, for example, by processing a resist material in a spherical or hemispherical shape through a photolithography technique. As the processing method, for example, various publicly-known methods used for forming an on-chip lens (OCL) in a field of imager can be applied. 
     Alternatively, for example, the reflector  119  having the recursive structure of the bead type may be formed by arranging beads (particles) made of glass, plastic, or the like dispersedly inside the resin layer. According to this configuration, since the reflector  119  can be formed merely by dispersedly arranging commercially available beads in an appropriate resin layer, the reflector  119  can be formed more easily at a lower cost. 
     Further, the reflector  119  may not be formed directly on the protection film  31 , and for example, the reflector  119  may be formed above the protection film  31  by boding a separately prepared reflector  119  to a predetermined position on the protection film  31 . Further, the recursive structure formed in the reflector  119  is not limited to the above example, and various publicly-known structures may be applied as the recursive structure. 
     Further, in the third embodiment, the lower surface of the reflector  119  need not be necessarily a recursive reflector. For example, the lower surface of the reflector  119  may be a mirror or a scatterer. Even in a case in which the lower surface of the reflector  119  is a mirror or a scatterer, some components of light incident on the reflector  119  can be reflected toward the luminescence surface of the light emitting element  10 , and thus a constant effect related to the improvement of the light extraction efficiency can be obtained. Here, in a case in which the lower surface of the reflector  119  is a recursive reflector, it is possible to more efficiently reflect the light incident on the reflector  119  toward the luminescence surface of the light emitting element  10 , and thus in order to more remarkably obtain the effect of improving the light extraction efficiency, it is more preferable to configure the lower surface of the reflector  119  with the recursive reflector. 
     The reflector  119  in which the lower surface is a mirror or a scatterer may be formed by various methods. For example, as the method of forming the reflector  119  in which the lower surface is a mirror or a scatterer, for example, a method in which an appropriate material is deposited by vapor deposition or sputtering to form a film, an appropriate material (a resist material) is formed in a film form by a lithography technique, a mirror or scatterer is bonded onto the protection film  31 , and a surface shape of a master having a surface shape of a separately prepared mirror or scatterer is transferred onto the film of the appropriate material, or a material functioning a mirror or a scatterer is coated when it has a film form. 
     After the reflector  119  is formed on the protection film  31 , a planarizing film  32  is laminated. The planarizing film  32  corresponds to the planarizing film  111  described above. The planarizing film  32  is formed, for example, by depositing SiO 2  at a predetermined film thickness (about 2.0 um) through a CVD technique and planarizes the surface thereof through a CMP technique or the like. However, the materials and the film thicknesses of the planarizing film  32  are not limited to these examples, and the planarizing film  32  may contain various publicly-known materials used as a planarizing film of a common organic EL display so as to have film thicknesses commonly employed in an organic EL display, as appropriate. 
     Here, in the third embodiment, it is preferable that the material of the protection film  31  be selected such that the refractive index n 3  of the protection film  31  is equal to the refractive index n 1  of the first member  51  or smaller than the refractive index n 1  of the first member  51 . Furthermore, the materials of the protection film  31  and the planarizing film  32  are selected such that the absolute value of the difference between the refractive index n 3  of the protection film  31  and the refractive index n 4  of the planarizing film  32  is preferably less than or equal to 0.30 and more preferably less than or equal to 0.20. By thus selecting the materials of the protection film  31  and the planarizing film  32 , the reflection or scattering of emission light from the light emitting element  10  at the interface between the first member  51  and the protection film  31  and the interface between the protection film  31  and the planarizing film  32  can be suppressed, and light extraction efficiency can be further improved. 
     Note that, as the configuration from the first substrate  11  to the protection film  31  of the display device  1   i , particularly as the configuration of the reflector  53 , the configuration of a display device disclosed in JP 2013-191533A, which is a prior application by the present applicant, may be used, for example. 
     A CF layer  33  is formed on the planarizing film  32 . The CF layer  33  corresponds to the CF layer  113  described above. The CF layer  33  is formed so that CFs of respective colors (a red CF  33 R, a green CF  33 R, and a blue CF  33 B) having a predetermined area are formed with respect to the respective light emitting elements  10 . The CF layer  33  may be formed by performing exposure on a resist material into a prescribed configuration and performing development by photolithography technology, for example. The film thickness of the CF layer  33  is approximately 2 μm, for example. However, the material, the formation method, and the film thickness of the CF layer  33  are not limited to these examples, and the CF layer  33  may be formed so as to have a film thickness commonly employed in an organic EL display by using various publicly-known materials that are used as a CF layer of a common organic EL display and various publicly-known methods, as appropriate. 
     The second substrate  34  is stuck to the upper side of the CF layer  33  via, for example, a sealing resin film  35  of an epoxy resin or the like, and thereby the display device  1   i  is fabricated. Note that the material of the sealing resin film  35  is not limited to this example, and the material of the sealing resin film  35  may be selected in view of high transmissivity to the emission light from the light emitting element  10 , excellence in adhesiveness to the CF layer  33  located on the lower side and the second substrate  34  located on the upper side, low reflectivity at the interface between the CF layer  33  located on the lower side and the second substrate  34  located on the upper side, etc., as appropriate. 
     The specific configuration example of the display device  1   i  according to the third embodiment has been described above. Further, the specific configuration examples of the display devices according to the respective embodiments and the respective modified examples of the present disclosure are not limited to the above examples. Various kinds of conditions commonly used for forming a layer can be used as a material, a film thickness, and a forming method of each of layers constituting the display device according to the respective embodiments and the respective modified examples.

     8. Supplement 
     The preferred embodiment(s) of the present disclosure has/have been described above with reference to the accompanying drawings, whilst the present disclosure is not limited to the above examples. A person skilled in the art may find various alterations and modifications within the scope of the appended claims, and it should be understood that they will naturally come under the technical scope of the present disclosure. 
     For example, the configurations that the display device according to each of the embodiments can have and the configurations that the display devices according to the modification examples can have, which are described hereinabove, may be used in combination with each other within the extent of feasibility. For example, the methods described above may be combined in order to create a relative misalignment between the light emitting element and the CF, as appropriate. Further, for example, a reflector structure may be formed in the display devices according to the first embodiment and the modified example thereof. In other words, in the display device in which the reflector is formed in at least some pixels, a reflector structure may be formed without causing the relative misalignment between the light emitting element and the reflector. 
     Further, although in each of the embodiments described hereinabove the display device  1  has a configuration in which one pixel includes sub-pixels of four colors of a red pixel, a green pixel, a blue pixel, and a white pixel, the present disclosure is not limited to this example. By applying configurations similar to those of the display devices according to the respective embodiments to display devices having other pixel configurations, similar effects can be obtained. Further, the method for arranging pixels is not limited to the delta arrangement described above, either. For example, similar effects can be obtained also by other pixel arrangements such as a stripe arrangement, a diagonal arrangement, and a rectangle arrangement. 
     For example, although in the above an embodiment in which the display device is an organic EL display is described as an example of the present disclosure, the present disclosure is not limited to this example. The display device that is an object of the present disclosure may be various display devices as long as they are display devices that can achieve color display by using CFs, such as a liquid crystal display, a plasma display, and an electronic paper device. When the light emitting section and the reflector are arranged in the other display devices in a state in which the center of the reflector is shifted from the center of the luminescence surface of the light emitting section in a plane perpendicular to the stacking direction so that the light emitted in a direction other than a desired direction among the emission light from the light emitting section is reflected in at least a partial region in the display surface, effects similar to those of the respective embodiments described above can be obtained. Here, the light emitting section is a part that is included in each pixel of the display device and that emits light toward the outside. For example, in an organic EL display like each of the embodiments described hereinabove, the light emitting section corresponds to a light emitting element. Further, for example in a liquid crystal display, the light emitting section corresponds to a region corresponding to one pixel of a liquid crystal panel. Further, for example in a plasma display, the light emitting section corresponds to a region corresponding to one discharge cell of a plasma display panel. 
     Further, the effects described in this specification are merely illustrative or exemplified effects, and are not limitative. That is, with or in the place of the above effects, the technology according to the present disclosure may achieve other effects that are clear to those skilled in the art from the description of this specification.
