[0004] When a camera area is formed on the display unit, a light-emitting element is formed in the camera area so that the camera area functions as a part of the display unit. In this case, diffraction occurs in the imaging light passing between the electrodes of the light-emitting element, which may degrade the quality of the image captured by the camera unit.

[0005] A light-emitting device according to one embodiment of the present disclosure comprises a display unit including a camera area that takes in imaging light and a non-camera area, wherein the non-camera area includes a plurality of first light-emitting elements each having an electrode and emitting a first color, and the camera area includes a plurality of second light-emitting elements each having an electrode and emitting the first color, wherein the plurality of first light-emitting elements are formed so that the electrode centers of each coincide with the intersections of a virtual regular grid pattern of the display unit, and the plurality of second light-emitting elements are formed so that the electrode centers of each are offset from the intersections.

[0006] The interference between diffracted light beams of imaging light passing through the camera area is reduced, and degradation of imaging quality in the camera area is reduced.

[0008] [Embodiment 1] <Overview of Display Device> Fig. 2 is a schematic plan view of a display device 1. The display device 1 includes a display unit DA and a frame unit NA formed around the periphery of the display unit DA. The display device 1 performs display on the display unit DA by controlling light emission from each of a plurality of light-emitting elements (described later) formed in the display unit DA. Drivers and the like for driving each of the plurality of light-emitting elements of the display unit DA may be formed in the frame unit NA.

[0009] In this embodiment, a plan view of the display device 1 refers to viewing the display device 1 from a direction perpendicular to the upper surface, which is the light-emitting surface of the display unit DA of the display device 1. In this specification, as shown in Fig. 2, a direction from above to below the display device 1 in a plan view of the display device 1 is referred to as a first direction D1, and a direction from left to right of the display device 1 is referred to as a second direction D2. Hereinafter, in each drawing of this specification except for Fig. 4, the first direction D1 is referred to as a direction from above to below the paper surface, and the second direction D2 is referred to as a direction from left to right on the paper surface.

[0010] The display device 1 according to this embodiment includes, for example, a light-emitting element formed for each subpixel of the display unit DA. The light-emitting element includes, for example, a pixel electrode formed for each subpixel, a common electrode formed in common to the plurality of subpixels, and a functional layer including a light-emitting layer formed between the pixel electrode and the common electrode. The display unit DA drives each pixel electrode based on a signal input from a driver in the frame unit NA to control the light emission of each light-emitting element and perform display.

[0011] Hereinafter, unless otherwise specified, each pixel electrode in the display unit DA is a light-reflecting electrode that reflects visible light, and the common electrode is a transmissive electrode that transmits visible light. Also, each pixel electrode in the display unit DA is an anode of a light-emitting element, and the common electrode is a cathode of the light-emitting element. Note that each pixel circuit that drives each pixel electrode in the display unit DA may be made of a material that reflects visible light.

[0012] In this embodiment, the display unit DA includes a first display area A1 as a non-camera area, a second display area A2 as a camera area, and a third display area A3 as a non-camera area. For example, the second display area A2 and the third display area A3 are formed further inward in the display unit DA than the first display area A1. Furthermore, the second display area A2 is formed further inward in the display unit DA than the third display area A3. For example, the second display area A2 has a substantially circular shape in a planar view of the display device 1. In this case, the third display area A3 is, for example, located between the first display area A1 and the second display area A2 and has a ring shape of substantially the same width in a planar view of the display device 1.

[0013] <First Display Area> The first display area A1, the second display area A2, and the third display area A3 will be described in more detail with reference to Figures 1 and 3. Figure 3 is a schematic enlarged view of area E1 shown in Figure 2, in other words, a diagram showing the display unit DA with the second display area A2, the third display area A3, and the first display area A1 near the second display area A2. Figure 1 is a schematic enlarged view of area E2 shown in Figure 3, in other words, a diagram showing further enlarged views of the vicinity of the boundary between the first display area A1 and the third display area A3 and the vicinity of the boundary between the second display area A2 and the third display area A3.

[0014] 3, only pixel electrodes (described later) of each light-emitting element are shown. In other words, each pixel electrode is shown through a functional layer formed for each pixel electrode and a common electrode formed in common to multiple pixel electrodes. Also, in FIG. 1, only one of the transparent wirings 46 electrically connected to each pixel electrode, an electrode 21E (described later), and one of the pixel circuits 21D that drives the electrode 21E are shown.

[0015] 3, the first display area A1 includes, for example, a plurality of first light-emitting elements, namely, light-emitting elements 11, light-emitting elements 12, and light-emitting elements 13. The light-emitting elements 11, light-emitting elements 12, and light-emitting elements 13 are two-dimensionally arranged on the first display area A1.

[0016] Light-emitting element 11, light-emitting element 12, and light-emitting element 13 each include electrodes 11E, 12E, and 13E. Electrodes 11E, 12E, and 13E are pixel electrodes formed for each subpixel of display unit DA. As will be described later, display device 1 includes functional layers for each light-emitting element formed at positions overlapping electrodes 11E, 12E, and 13E, respectively, in a plan view of display device 1, and a common electrode shared by each pixel electrode. Therefore, as shown in FIG. 1 , light-emitting region 11L, light-emitting region 12L, and light-emitting region 13L are formed in first display region A1 at positions overlapping electrodes 11E, 12E, and 13E, respectively, in a plan view of display device 1.

[0017] 1 , a virtual regular grid pattern including a plurality of first grid lines GL1 extending along a first direction D1 and a plurality of second grid lines GL2 extending along a second direction D2 is formed on the display unit DA of the display device 1. The first grid lines GL1 are formed at approximately regular intervals in the second direction D2, and the second grid lines GL2 are formed at approximately regular intervals in the first direction D1. In this embodiment, as shown in FIG. 1 , virtual intersection points P of the regular grid pattern are formed on the display unit DA of the display device 1 at each of the intersections of the first grid lines GL1 and the second grid lines GL2.

[0018] In this embodiment, each light-emitting element in the first display region A1 is formed so that the electrode center of the respective pixel electrodes coincides with an intersection point P of the virtual regular grid pattern. In other words, in a plan view of the display device 1, the electrode center of each of electrodes 11E, 12E, and 13E is formed at a position that overlaps with one of the multiple intersection points P. Therefore, each of light-emitting elements 11, 12, and 13 is arranged along the first direction D1 and the second direction D2.

[0019] For example, the distance between two adjacent intersections P is defined as a distance LP. In this case, each electrode 11E is formed such that the electrode center is twice the distance LP in each of the first direction D1 and the second direction D2 from the adjacent electrode 11E. Furthermore, each electrode 12E is formed such that the electrode center is twice the distance LP in one of the first direction D1 and the second direction D2 from the adjacent electrode 12E. Furthermore, like each electrode 11E, each electrode 13E is formed such that the electrode center is twice the distance LP in each of the first direction D1 and the second direction D2 from the adjacent electrode 13E. Furthermore, each electrode 12E is formed such that the electrode center is twice the distance LP in each of the first direction D1 and the second direction D2 from the adjacent electrode 11E and electrode 13E.

[0020] Therefore, in the first display region A1, the distance between adjacent electrodes 11E and 12E is the same. Similarly, in the first display region A1, the distance between adjacent electrodes 12E and 13E is the same, and the distance between adjacent electrodes 11E and 13E is the same.

[0021] Electrode 11E and electrode 13E may have, for example, a square shape in a plan view of the display device 1. In this case, the electrode centers of electrode 11E and electrode 13E may be the intersection of two diagonal lines. Furthermore, electrode 12E may have, for example, a rounded rectangle in a plan view of the display device 1, in which a pair of straight lines facing each other are connected by a curve. In a plan view of the display device 1, one of two adjacent electrodes 12E may have a longitudinal direction perpendicular to the other. In this case, the electrode center of electrode 12E may be the intersection of the bisectors of electrode 12E in the longitudinal and lateral directions of electrode 12E.

[0022] For example, in a plan view of the display device 1, each of the light-emitting regions 11L, 12L, and 13L may have a shape similar to that of the electrodes 11E, 12E, and 13E, respectively. In this case, in a plan view of the display device 1, the centers of the light-emitting regions 11L, 12L, and 13L may coincide with the centers of the electrodes 11E, 12E, and 13E, respectively.

[0023] In a plan view of the display device 1, the electrode area of ​​each electrode 13E may be smaller than the electrode area of ​​each electrode 11E, and the electrode area of ​​each electrode 12E may be smaller than the electrode area of ​​each electrode 13E. Accordingly, in a plan view of the display device 1, the area of ​​each light-emitting region 13L may be smaller than the area of ​​each light-emitting region 11L, and the area of ​​each light-emitting region 12L may be smaller than the area of ​​each light-emitting region 13L.

[0024] For example, in this embodiment, light-emitting element 11 may emit light of a first color, light-emitting element 12 may emit light of a second color, and light-emitting element 13 may emit light of a third color. In this specification, for example, the first color may be blue, the second color may be green, and the third color may be red. In other words, light-emitting element 11 may be a blue light-emitting element that emits blue light, light-emitting element 12 may be a green light-emitting element that emits green light, and light-emitting element 13 may be a red light-emitting element that emits red light.

[0025] In this embodiment, blue light refers to light having a central emission wavelength in a wavelength band of, for example, 380 nm or more and 500 nm or less. Green light refers to light having a central emission wavelength in a wavelength band of, for example, more than 500 nm and less than 600 nm. Red light refers to light having a central emission wavelength in a wavelength band of, for example, more than 600 nm and less than 780 nm.

[0026] The first display area A1 includes, for example, a pixel circuit for driving a pixel electrode for each light-emitting element. Each pixel circuit may drive each pixel electrode based on a signal transmitted from a driver in the frame portion NA to control light emission from each light-emitting portion. Each pixel circuit may include a thin-film transistor formed by a method described below.

[0027] For example, the display unit DA may include a plurality of first signal lines extending substantially vertically of the display device 1 and a plurality of second signal lines extending substantially horizontally of the display device 1. A signal may be applied to each of the first and second signal lines from a driver in the frame unit NA. In this case, in the first display region A1, in a plan view of the display device 1, each of the first and second signal lines may overlap with a corresponding first grid line GL1 and a corresponding second grid line GL2. In other words, in the first display region A1, in a plan view of the display device 1, the intersections of each of the first grid line GL1 and each of the second grid lines GL2 may coincide with the intersections P. In this case, the display device 1 can arrange pixel circuits driving each light-emitting element in the first display region A1 near each light-emitting element, thereby reducing the need for wiring or the like. Each pixel circuit may drive each light-emitting element in response to a signal from the corresponding first signal line and second signal line.

[0028] In this embodiment, a set including at least one each of light-emitting elements 11, 12, and 13 may be considered a pixel in the first display region A1. For example, the first display region A1 may have a plurality of pixels including one light-emitting element 11, two light-emitting elements 12, and one light-emitting element 13. In this case, the pixel electrodes of the two light-emitting elements 12 included in the same pixel may be short-circuited and may be driven by the same pixel circuit. In other words, each of the four light-emitting elements included in a pixel may be driven by three pixel circuits.

[0029] <Second Display Area> The second display area A2 includes, for example, a plurality of light-emitting elements 21 as second light-emitting elements, a plurality of light-emitting elements 22 as fourth light-emitting elements, and a plurality of light-emitting elements 23 as fifth light-emitting elements. Each of the light-emitting elements 21, 22, and 23 may have the same configuration as each of the light-emitting elements 11, 12, and 13, except for differences in their formation positions and shapes.

[0030] For example, light-emitting element 21, light-emitting element 22, and light-emitting element 23 each include electrodes 21E, 22E, and 23E. Electrodes 21E, 22E, and 23E are pixel electrodes formed for each subpixel of display unit DA. As will be described later, display device 1 includes functional layers for each light-emitting element formed at positions overlapping electrodes 21E, 22E, and 23E, respectively, in a plan view of display device 1, and a common electrode shared by each pixel electrode. Therefore, as shown in FIG. 1 , light-emitting region 21L, light-emitting region 22L, and light-emitting region 23L are formed in second display region A2 at positions overlapping electrodes 21E, 22E, and 23E, respectively, in a plan view of display device 1.

[0031] In this embodiment, each light-emitting element in the second display region A2 is formed so that the electrode center of each pixel electrode is shifted from the intersection point P. In other words, in a plan view of the display device 1, the electrode centers of electrodes 21E, 22E, and 23E in the second display region A2 are formed at positions shifted from the intersection point P.

[0032] For example, in this embodiment, the light-emitting element 21 may emit light of a first color, the light-emitting element 22 may emit light of a second color, and the light-emitting element 23 may emit light of a third color. In other words, the light-emitting element 21 may be a blue light-emitting element that emits blue light, the light-emitting element 22 may be a green light-emitting element that emits green light, and the light-emitting element 23 may be a red light-emitting element that emits red light.

[0033] In this embodiment, a set including at least one each of the light-emitting elements 21, 22, and 23 in the second display region A2 may be considered a pixel in the second display region A2. For example, the second display region A2 may have a plurality of pixels including one light-emitting element 21, two light-emitting elements 22, and one light-emitting element 23. In other words, the number of light-emitting elements 22 may be greater than the number of light-emitting elements 21. In this case, the electrodes 22E of two light-emitting elements 22 included in the same pixel may be short-circuited and may be driven by the same pixel circuit. In other words, each of the four light-emitting elements included in a pixel may be driven by three pixel circuits.

[0034] In a plan view of the display device 1, the electrode area of ​​each electrode 23E may be smaller than the electrode area of ​​each electrode 21E, and the electrode area of ​​each electrode 22E may be smaller than the electrode area of ​​each electrode 23E. Accordingly, in a plan view of the display device 1, the area of ​​each light-emitting region 23L may be smaller than the area of ​​each light-emitting region 21L, and the area of ​​each light-emitting region 22L may be smaller than the area of ​​each light-emitting region 23L.

[0035] Generally, the human eye has a higher luminance sensitivity to green light than to blue and red light, and also a higher luminance sensitivity to red light than to blue light. Therefore, when the light-emitting element 21 emits blue light, the light-emitting element 22 emits green light, and the light-emitting element 23 emits red light, the display device 1 can improve its apparent resolution by providing more light-emitting elements 22 than light-emitting elements of other colors. Furthermore, by reducing the areas of the light-emitting region 21L, the light-emitting region 23L, and the light-emitting region 22L in this order, the display device 1 can more easily improve its apparent white balance. Furthermore, by reducing the area of ​​each light-emitting region and the area of ​​the pixel electrode, the proportion of the area of ​​the light-transmitting region A4 in the second display region A2 can be increased.

[0036] <Third Display Region> The third display region A3 includes, for example, a plurality of the above-described light-emitting elements 21, 22, and 23. The light-emitting elements 21, 22, and 23 in the third display region A3 may have the same configuration as the light-emitting elements 21, 22, and 23 in the second display region A2, respectively, except for their relative positions.

[0037] Each light-emitting element in the third display region A3 is formed so that the electrode center of the respective pixel electrode coincides with the intersection point P. In other words, in a plan view of the display device 1, the electrode centers of electrodes 21E, 22E, and 23E in the third display region A3 are formed at positions that overlap with one of the multiple intersection points P. Therefore, each of light-emitting elements 21, 22, and 23 in the third display region A3 is arranged along the first direction D1 and the second direction D2.

[0038] Therefore, in the third display area A3, the distance between electrodes 21E and 22E that are close to each other is the same, the distance between electrodes 22E and 23E that are close to each other is the same, and the distance between electrodes 21E and 23E that are close to each other is the same.

[0039] The third display region A3 further includes pixel circuits for driving the light-emitting elements in the second display region A2. In other words, the pixel circuits for driving the light-emitting elements in the second display region A2 are formed around the second display region A2 in a plan view of the display device 1. For example, as shown in FIG. 1 , the third display region A3 includes a pixel circuit 21D for driving the light-emitting elements 21 in the second display region A2. For example, the pixel circuit 21D drives the light-emitting elements 21 in the second display region A2 via transparent wiring 46, which will be described later.

[0040] 1, the third display region A3 may include pixel circuits that drive the light-emitting elements 22 and 23 in the second display region A2, respectively. The third display region A3 may also include pixel circuits that drive the light-emitting elements in the third display region A3.

[0041] <Layer Structure> The layer structure of the display device 1 in the second display area A2 and the third display area A3 will be described in detail with reference to Fig. 4. Fig. 4 is a schematic side cross-sectional view showing an enlarged view of the vicinity of the second display area A2 and the third display area A3 in a plane substantially perpendicular to the display surface of the display device 1.

[0042] The display device 1 includes a light-transmitting substrate 31, such as a glass substrate or a film substrate. The display device 1 also includes a first inorganic interlayer film 32, a second inorganic interlayer film 33, a third inorganic interlayer film 34, a first organic interlayer film 35, a second organic interlayer film 36, a third organic interlayer film 37, and a fourth organic interlayer film 38, all of which are light-transmitting, arranged in this order on the substrate 31. The substrate 31, the inorganic interlayer films, and the organic interlayer films may be formed in a display unit DA that includes a first display region A1, a second display region A2, and a third display region A3.

[0043] The first inorganic interlayer film 32, the second inorganic interlayer film 33, and the third inorganic interlayer film 34 are formed, for example, by depositing an inorganic oxide film or the like using a CVD method or the like. The first organic interlayer film 35, the second organic interlayer film 36, the third organic interlayer film 37, and the fourth organic interlayer film 38 are formed, for example, by depositing an organic coating film having optical transparency, such as polyimide, using a coating method or a photolithography method or the like. The display device 1 further includes a common electrode 39 formed on the upper surface of the fourth organic interlayer film 38, which is shared by the pixel electrodes of the display unit DA.

[0044] In this embodiment, each pixel electrode in the second display region A2 and the third display region A3, including the electrode 21E, is formed between the third organic interlayer film 37 and the fourth organic interlayer film 38. For example, in the second display region A2 and the third display region A3, a functional layer 21F including a light-emitting layer is formed between each electrode 21E and the common electrode 39. As a result, in the second display region A2 and the third display region A3, each light-emitting element 21 is formed by each electrode 21E, each functional layer 21F, and the common electrode 39.

[0045] Each pixel electrode in the first display region A1 may be formed between the third organic interlayer film 37 and the fourth organic interlayer film 38. For example, also in the first display region A1, a functional layer including a light-emitting layer may be formed between each pixel electrode and the common electrode 39. As a result, each pixel electrode, each functional layer, and the common electrode 39 may form a light-emitting element in the first display region A1.

[0046] When each pixel electrode in the display unit DA is an anode of a light-emitting element, each functional layer in the display unit DA may include, for example, a hole transport layer, a light-emitting layer, and an electron transport layer, in this order from the pixel electrode side. In this case, the light-emitting layer may be, for example, an organic light-emitting layer containing an organic light-emitting material. In other words, the display unit DA of the display device 1 may include an OLED panel having a plurality of organic light-emitting elements. Alternatively, the light-emitting layer may be, for example, a quantum dot light-emitting layer containing semiconductor nanoparticles, in other words, quantum dots, as a light-emitting material.

[0047] The display device 1 drives the light emitting elements 21 to emit the first color light LR from the light emitting layers of the functional layer 21F, thereby performing display in the display unit DA including the second display area A2 and the third display area A3.

[0048] Furthermore, in the third display region A3, the display device 1 includes, in order from the substrate 31 side, a first conductive film 41, a semiconductor film 42, a second conductive film 43, a third conductive film 44, a fourth conductive film 45, and transparent wiring 46. The first conductive film 41 is located between the substrate 31 and the first inorganic interlayer film 32. The semiconductor film 42 is located between the first inorganic interlayer film 32 and the second inorganic interlayer film 33. The second conductive film 43 is located between the second inorganic interlayer film 33 and the third inorganic interlayer film 34. The third conductive film 44 is located between the third inorganic interlayer film 34 and the first organic interlayer film 35. The fourth conductive film 45 is located between the first organic interlayer film 35 and the second organic interlayer film 36. The transparent wiring 46 is located between the second organic interlayer film 36 and the third organic interlayer film 37.

[0049] Here, the transparent wiring 46 is electrically connected to the fourth conductive film 45 through a contact hole 46C formed in the second organic interlayer film 36. The transparent wiring 46 is also routed to the second display region A2, and is electrically connected to the electrode 21E through a contact hole 21C formed in the third organic interlayer film 37.

[0050] The first conductive film 41, the second conductive film 43, the third conductive film 44, and the fourth conductive film 45 are all electrically conductive and may be, for example, a light-reflective conductive film including a metal film. The transparent wiring 46 is a transparent member that is light-transmitting and electrically conductive. Each pixel circuit in the third display region A3 may be formed by forming a thin-film transistor using the first conductive film 41, the semiconductor film 42, the second conductive film 43, the third conductive film 44, and the fourth conductive film 45.

[0051] The pixel circuits that drive the light-emitting elements in the third display region A3 may be formed by forming thin-film transistors in the third display region A3, as with the pixel circuits that drive the light-emitting elements in the second display region A2. The pixel circuits that drive the light-emitting elements in the first display region A1 may be formed by forming thin-film transistors in the first display region A1. Therefore, the first conductive film 41, the semiconductor film 42, the second conductive film 43, the third conductive film 44, and the fourth conductive film 45 may also be formed in the first display region A1.

[0052] 4 , in this embodiment, the functional layer of each light-emitting element in the display unit DA, which includes the first display region A1, the second display region A2, and the third display region A3, is formed in an opening formed in the fourth organic interlayer film 38. For example, the functional layer may be formed by forming, after forming from the substrate 31 to the fourth organic interlayer film 38, openings in the fourth organic interlayer film 38 at positions overlapping with each pixel electrode in a plan view of the display device 1, and then forming a layer containing a material for the functional layer in the openings.

[0053] In this case, the openings in the fourth organic interlayer film 38 in the second display region A2 may be misaligned in position in accordance with the misalignment of the pixel electrodes corresponding to the openings. In other words, in a plan view of the display device 1, the centers of the openings in the fourth organic interlayer film 38 in the second display region A2 may be misaligned from the intersection P. This makes it possible to misalign the centers of the light-emitting regions of each light-emitting element in the second display region A2 from the intersection P in accordance with the misalignment between the electrode centers of the pixel electrodes of each light-emitting element in the second display region A2 and the intersection P.

[0054] For example, the formation pattern of the material of the functional layer in the second display region A2 may be the same as the formation pattern of the material of the functional layer in the first display region A1 and the third display region A3. In this case, the position of each opening of the fourth organic interlayer film 38 in the second display region A2 may be shifted so that the position of each opening of the fourth organic interlayer film 38 in the second display region A2 is included in the formation position of each functional layer in the second display region A2 in a plan view of the display device 1.

[0055] For example, in a plan view of the display device 1, the pixel electrode of each light-emitting element in the second display region A2 may overlap the intersection P. Furthermore, the magnitude of the deviation between the electrode center of the pixel electrode of each light-emitting element in the second display region A2 and each intersection P may be equal to or less than half the diameter of the light-emitting region of each light-emitting element in the second display region A2. This makes it possible to reduce the possibility that the functional layer will not be formed in part of the opening of the fourth organic interlayer film 38 in the second display region A2, even with the above-mentioned method.

[0056] For example, the functional layer may be formed by vapor deposition using a vapor deposition mask, such as a metal mask, having a plurality of openings. In this case, the vapor deposition mask may have the same opening shape and arrangement pattern at positions corresponding to the first display region A1 and the third display region A3 and at a position corresponding to the second display region A2. Even in this case, the formation positions of the light-emitting regions in the second display region A2 can be controlled by controlling the positions of the openings in the fourth organic interlayer film 38 in the second display region A2 in a plan view of the display device 1.

[0057] Furthermore, for example, suppose the functional layer is formed by an inkjet method in which the material of the functional layer is dropped into the openings of the fourth organic interlayer film 38. In this case, the positions at which the material of the functional layer is dropped may be positions corresponding to each intersection P in any of the first display region A1, the second display region A2, and the third display region A3. In this case, as long as each opening of the fourth organic interlayer film 38 in the second display region A2 overlaps with the intersection P in a plan view of the display device 1, it is possible to reduce the possibility that the functional layer will not be formed in some of the openings of the fourth organic interlayer film 38 in the second display region A2.

[0058] <Capturing imaging light into the camera> In the second display region A2, the display device 1 further includes a camera unit CU as a camera equipped with an imaging element and the like, on the side of the substrate 31 opposite the light-emitting element 21. Imaging light LT incident from the display surface side of the display device 1 is incident on the camera unit CU. In particular, in the second display region A2, except for each pixel electrode, a light-transmitting member including transparent wiring 46 is formed. Therefore, a light-transmitting region A4 is formed between each pixel electrode in the second display region A2, through which the imaging light LT passes from the common electrode 39 to the camera unit CU.

[0059] Therefore, the imaging light LT incident on the light-transmitting region A4 from the display surface side of the display device 1 is captured by the camera unit CU. This allows the display device 1 to capture an image of the display surface side of the substrate 31 using the camera unit CU. Therefore, the display device 1 can, for example, perform a display on an OLED panel, while capturing an image of the display surface side of the OLED panel using the camera unit CU. Note that the display device 1 may also capture an image from the back side of the display device 1, i.e., the side opposite the display surface of the substrate 31, using the camera unit CU.

[0060] As described above, the imaging light LT from the display surface side of the display device 1 is captured by the camera unit CU in the light-transmitting region A4 located between the pixel electrodes in the second display region A2. Therefore, the imaging light LT captured by the camera unit CU passes through the gaps between the pixel electrodes in the second display region A2.

[0061] <Interference of Diffracted Light of Imaging Light> Here, the influence of each pixel electrode in the second display region A2 on the imaging light LT taken into the camera unit CU will be considered.

[0062] For example, in a plan view of the display device 1, the electrode center of each pixel electrode in the second display region A2 coincides with a certain intersection P, just like the electrode centers of each pixel electrode in the first display region A1 and the third display region A3. In this case, the positional relationship between each of the pixel electrodes in the second display region A2 and the adjacent pixel electrodes is approximately the same. Therefore, in either direction along the display surface of the display device 1, there are periodically arranged portions in the second display region A2 where pixel electrodes are formed and portions where pixel electrode wiring is not formed.

[0063] The imaging light LT incident on the light-transmitting region A4 is diffracted as it passes through each of the pixel electrodes, and the multiple diffracted light beams may interfere with each other. Here, if the electrode centers of the pixel electrodes in the second display region A2 are on the intersection P, the pixel electrodes in the light-transmitting region A4 are periodically arranged, and therefore the pixel electrodes may behave like a diffraction grating, which may intensify the interference of the diffracted light described above.

[0064] When multiple beams of imaging light LT captured by the camera unit CU interfere with each other, light of a particular wavelength is enhanced or attenuated, which may result in a decrease in the quality of imaging by the camera unit CU.

[0065] In this embodiment, each light-emitting element in the second display region A2 is formed so that the electrode center of each pixel electrode is offset from the intersection point P. This reduces the periodicity of the presence or absence of pixel electrodes in the light-transmitting region A4 in any direction on the display surface. Therefore, the display device 1 according to this embodiment can reduce interference between the diffracted light of the imaging light LT passing through each pixel electrode. Therefore, the display device 1 reduces interference between the diffracted light of the imaging light LT taken into the camera unit CU from the second display region A2, particularly the light-transmitting region A4, and reduces degradation in the quality of imaging by the camera unit CU.

[0066] <Addendum> In this embodiment, each light-emitting element in the second display region A2 may be formed, for example, such that the electrode center of any pixel electrode is shifted from the intersection point P. With the above configuration, the display device 1 can more efficiently reduce the periodicity of the presence or absence of pixel electrodes for each light-emitting element in the second display region A2.

[0067] In this embodiment, the direction and distance of the displacement of the electrode center of each light-emitting element in the second display region A2 from the intersection P may be random. For example, in this embodiment, the direction and distance of the displacement of each pixel electrode in the second display region A2 from the intersection P may be determined according to a separately generated random number table.

[0068] With the above configuration, the periodicity of the arrangement positions of the pixel electrodes in the second display area A2 is further reduced compared to when the deviation is determined according to a predetermined rule, and therefore, with the above configuration, the display device 1 can further reduce interference between diffracted light of the imaging light LT taken into the camera unit CU from the light-transmitting area A4.

[0069] In the present embodiment, in a plan view of the display device 1, the electrodes 21E, 22E, and 23E may each be formed at a position overlapping the intersection P. With the above configuration, the display device 1 reduces excessive deviation between the center of the light-emitting region of each light-emitting element in the second display region A2 and the intersection P, thereby reducing degradation of display quality in the second display region A2.

[0070] For example, in this embodiment, a random number table of X and Y coordinates may be set for each light-emitting element in the second display area A2, with distribution at equal probability within a range of half the diameter of the light-emitting area. In this embodiment, the direction and distance of deviation of the electrode center of each light-emitting element in the second display area A2 from the intersection P may be determined according to the random number table.

[0071] In this case, the deviation of the electrode center of each light-emitting element in the second display area A2 from the intersection P is equal to or less than half the diameter of each light-emitting area. With the above configuration, the display device 1 prevents the deviation between the center of the light-emitting area of ​​each light-emitting element in the second display area A2 and the intersection P from becoming too large, thereby preventing a decrease in display quality in the second display area A2.

[0072] The random number table may be expressed in polar form with the argument θ and the deviation r. The random number table may be set for the entire second display area A2. Alternatively, the second display area A2 may be divided into multiple small areas, and a separate random number table may be set for each small area, or the same random number table may be set for each small area.

[0073] Therefore, in the second display region A2, the distance between adjacent electrodes 21E and 22E may vary. Similarly, in the second display region A2, the distance between adjacent electrodes 22E and 23E may vary, and the distance between adjacent electrodes 21E and 23E may vary.

[0074] However, the electrode centers of some of the pixel electrodes in the second display region A2 may be formed to coincide with the intersection point P in a plan view of the display device 1. For example, the second display region A2 may include a light-emitting element 21 having an electrode 21E whose electrode center is shifted from the intersection point P, and may also include a light-emitting element 21 having an electrode 21E whose electrode center coincides with the intersection point P as a third light-emitting element.

[0075] Even with the above configuration, the electrode centers of some of the electrodes 21E of the light-emitting elements 21 in the second display region A2 are offset from the intersection P, so the display device 1 can reduce the periodicity of the presence or absence of pixel electrodes in the second display region A2. Meanwhile, with the above configuration, the electrode centers of some of the electrodes 21E of the light-emitting elements 21 in the second display region A2 overlap with the intersection P. Therefore, the display device 1 reduces the difference between the arrangement pattern of some of the light-emitting elements 11 in the first display region A1 and the arrangement pattern of the light-emitting elements 22 in the second display region A2. Therefore, the display device 1 according to this embodiment reduces the difference in display pattern between the first display region A1 and the second display region A2, improving display quality.

[0076] In this embodiment, the multiple intersections P are located along the first direction D1 and the second direction D2. Furthermore, the electrode center of the pixel electrode of each light-emitting element in the second display region A2 is offset from the intersections P in at least one of the first direction D1 and the second direction D2. This allows the display device 1 to reliably offset the electrode center of the pixel electrode of each light-emitting element in the second display region A2 from the intersections P using a simple configuration. In particular, the above-described offset of the electrode centers of each light-emitting element in the second display region A2 can be easily achieved by setting the offset according to the random number table of XY coordinates, as described above. Therefore, with the above configuration, the offset of the electrode centers of each light-emitting element in the second display region A2 can be achieved using a simple design.

[0077] In this embodiment, electrodes 21E, 22E, and 23E may each have a circular shape in a plan view of the display device 1. In this case, the center of each of electrodes 21E, 22E, and 23E may be the center of the circle. In other words, electrodes 21E, 22E, and 23E may each have a different shape from electrodes 11E, 12E, and 13E, respectively. In other words, the electrode shapes of each light-emitting element may be different between the first display region A1 and the second display region A2. With the above configuration, the display device 1 can further reduce interference of imaging light near the boundary with the first display region A1 and in the light-transmitting region A4 between the pixel electrodes of the light-emitting elements in the first display region A1 and the pixel electrodes of the light-emitting elements in the second display region A2.

[0078] Furthermore, the electrode areas of electrodes 21E, 22E, and 23E may be smaller than the electrode areas of electrodes 11E, 12E, and 13E, respectively. In other words, in a plan view of the display device 1, the size of the pixel electrode of each light-emitting element in the second display region A2 may be smaller than the size of the pixel electrode of each light-emitting element in the first display region A1. With the above configuration, the display device 1 can reduce the proportion of the area occupied by the pixel electrode of each light-emitting element in the second display region A2 in a plan view compared to the first display region A1. Therefore, the display device 1 can more easily ensure the area of ​​the light-transmitting region A4 in the second display region A2.

[0079] In addition, in a plan view of the display device 1, the size of the pixel electrode of each light-emitting element in the third display region A3 may also be smaller than the size of the pixel electrode of each light-emitting element in the first display region A1. This reduces the proportion of the area occupied by each pixel electrode in the third display region A3. Therefore, in the display device 1, it is easier to form pixel circuits in the third display region A3 that drive each light-emitting element in both the second display region A2 and the third display region A3.

[0080] Furthermore, for example, in a plan view of the display device 1, the light-emitting regions 21L, 22L, and 23L may each have a similar shape to the electrodes 21E, 22E, and 23E, respectively. In addition, in a plan view of the display device 1, the centers of the light-emitting regions 21L, 22L, and 23L may each coincide with the centers of the electrodes 21E, 22E, and 23E, respectively. With this configuration, the display device 1 can efficiently improve the ratio of the area of ​​the light-emitting region to the area of ​​the pixel electrode in each light-emitting element in the second display region A2.

[0081] In the present embodiment, in at least one pair of adjacent light-emitting elements 21 and 22, the directions in which the centers of the respective electrodes are shifted from the intersection P may differ from each other. In other words, in adjacent electrodes 21E and 22E, the directions in which the center of electrode 21E is shifted from the intersection P may differ from the directions in which the center of electrode 22E is shifted from the intersection P. With the above configuration, the display device 1 can further reduce interference of imaging light between the light-emitting elements 21 and 22.

[0082] Furthermore, in at least one pair of adjacent light-emitting elements 21 and 23, the directions in which the centers of the electrodes are shifted from the intersection P may differ from each other. In other words, in adjacent electrodes 21E and 23E, the directions in which the center of electrode 21E is shifted from the intersection P may differ from the directions in which the center of electrode 23E is shifted from the intersection P. With the above configuration, the display device 1 can further reduce interference of imaging light between the light-emitting elements 21 and 23.

[0083] The pixel electrode of each light-emitting element in the display unit DA is a light-reflecting electrode. Therefore, the display device 1 can more efficiently increase the intensity of light emitted from each light-emitting element. When the pixel electrode of each light-emitting element in the display unit DA is an anode, the display device 1 has greater flexibility in the material of the pixel electrode, allowing the pixel electrode to be a light-reflecting electrode. Meanwhile, since the light-transmitting region A4 is formed in the second display region A2, the display device 1 can capture imaging light into the camera unit CU while ensuring the intensity of light emitted from each light-emitting element.

[0084] In this embodiment, transparent wiring 46 is formed in the second display region A2, electrically connecting the pixel electrode of any light-emitting element in the second display region A2 to any pixel circuit in the third display region A3. Therefore, in the display device 1, pixel circuits for driving light-emitting elements having pixel electrodes connected to the transparent wiring 46 can be formed at positions away from the light-emitting elements. Furthermore, because the transparent wiring 46 is translucent, the display device 1 can reduce the interference caused by the transparent wiring 46 with the capture of imaging light into the camera unit CU, even when the transparent wiring 46 is formed in the translucent region A4.

[0085] In particular, the pixel circuits that drive each light-emitting element in the second display area A2 are located in a third display area A3 that is positioned around the second display area A2, and drive each light-emitting element in the second display area A2 via transparent wiring 46. Therefore, the display device 1 can reduce the interference with the capture of imaging light into the camera unit CU caused by the pixel circuits that drive each light-emitting element in the second display area A2.

[0086] [Embodiment 2] <Gradual Reduction of Pixel Electrodes> Fig. 5 is a further enlarged view showing the vicinity of the boundary between the first display region A1 and the third display region A3 and the vicinity of the boundary between the second display region A2 and the third display region A3 of the display device 1 according to this embodiment. In particular, Fig. 5 is a view showing positions corresponding to the schematic enlarged view shown in Fig. 1.

[0087] The display device 1 according to this embodiment is different from the display device 1 according to the previous embodiment in the size of the pixel electrode and the light-emitting area of ​​each light-emitting element in the second display area A2 and the third display area A3.

[0088] In this embodiment, the size of the electrode 21E of the light-emitting element 21 in the second display region A2 and the third display region A3 varies depending on the distance from the center of the second display region A2. In particular, in this embodiment, the size of the electrode 21E in the second display region A2 and the third display region A3 decreases as the electrode 21E approaches the center of the second display region A2. On the other hand, the size of the light-emitting region 21L in the second display region A2 and the third display region A3 may be constant regardless of the distance from the center of the second display region A2.

[0089] Similarly, in this embodiment, the size of the electrode 22E of the light-emitting element 22 in the second display region A2 and the size of the electrode 22E of the light-emitting element 22 in the third display region A3 may vary depending on the distance from the center of the second display region A2. In particular, in this embodiment, the size of the electrode 22E in the second display region A2 and the size of the electrode 23E in the third display region A3 may decrease as the distance approaches the center of the second display region A2. Furthermore, the size of the light-emitting region 22L in the second display region A2 and the size of the light-emitting region 23L in the third display region A3 may be constant regardless of the distance from the center of the second display region A2.

[0090] Except for the above configuration, the display device 1 according to this embodiment has the same configuration as the display device 1 according to the previous embodiment. For example, in this embodiment as well, in the second display region A2, the electrode centers of the pixel electrodes of each light-emitting element are offset from the intersection point P. Therefore, in this embodiment as well, the display device 1 reduces interference between diffracted light of the imaging light LT taken into the camera unit CU from the second display region A2, particularly the light-transmitting region A4, and reduces degradation in the quality of imaging by the camera unit CU.

[0091] In addition, in this embodiment, since the size of the electrode 21E of the light-emitting element 21 varies depending on the distance from the center of the second display area A2, the display device 1 can further reduce the periodicity of the presence or absence of pixel electrodes in the second display area A2.

[0092] In this embodiment, the size of the light-emitting region of each light-emitting element in the second display region A2 and the third display region A3 may be the same depending on the distance from the center of the second display region A2. On the other hand, the size of the light-emitting region of each light-emitting element in the second display region A2 and the third display region A3 may be different depending on the distance from the center of the second display region A2. For example, in the second display region A2 and the third display region A3, the size of the light-emitting region of each light-emitting element may be smaller as the pixel electrode of each light-emitting element becomes smaller.

[0093] Here, if there is a difference in the area of ​​the light-emitting regions of multiple light-emitting elements in the display device 1, there will also be a difference in the drive current value of the light-emitting element required to obtain the same brightness for the multiple light-emitting elements. In particular, the smaller the light-emitting area of ​​a light-emitting element in the display device 1, the larger the drive current value of the light-emitting element required to obtain the same brightness for the light-emitting element. In general, the brightness degradation of a light-emitting element tends to progress more quickly as the drive current value increases. Therefore, if there is a difference in the area of ​​the light-emitting regions of multiple light-emitting elements depending on the position of the display unit DA of the display device 1, there will also likely be a difference in the brightness degradation of the multiple light-emitting elements.

[0094] For example, in this embodiment, the size of electrode 21E gradually changes depending on the distance from the center of second display region A2, while the size of light-emitting region 21L remains constant regardless of the distance from the center of second display region A2. In this case, display device 1 according to this embodiment can reduce sudden changes in luminance degradation of each light-emitting element due to changes in the position of display unit DA, thereby improving display quality. In particular, display device 1 according to this embodiment reduces sudden changes in luminance degradation of each light-emitting element at the boundaries between first display region A1, second display region A2, and third display region A3, thereby reducing the visibility of these boundaries.

[0095] [Embodiment 3] <Periodic Arrangement of Pixel Electrodes of Green Light-Emitting Element> Fig. 6 is a further enlarged view showing the vicinity of the boundary between the first display region A1 and the third display region A3 and the vicinity of the boundary between the second display region A2 and the third display region A3 of the display device 1 according to this embodiment. In particular, Fig. 6 is a view showing positions corresponding to the schematic enlarged view shown in Fig. 1.

[0096] The display device 1 according to this embodiment differs from the display device 1 according to the first embodiment in that the electrode centers of the light-emitting elements 22 in the second display area A2 coincide with the intersection point P. In other words, the center of the electrode 22E according to this embodiment coincides with the intersection point P. Furthermore, the center of the light-emitting area 22L according to this embodiment may coincide with the intersection point P.

[0097] Therefore, the display device 1 according to this embodiment reduces the difference between the arrangement pattern of the light-emitting elements 12 in the first display area A1 and the arrangement pattern of the light-emitting elements 22 in the second display area A2. Therefore, the display device 1 according to this embodiment reduces the difference in the display pattern between the first display area A1 and the second display area A2, improving the display quality. In particular, when the light-emitting elements 12 and the light-emitting elements 22 emit green light, which is relatively more visible than blue light and red light, the display device 1 according to this embodiment more efficiently achieves the above-mentioned effects.

[0098] On the other hand, except for the above points, the display device 1 according to this embodiment has the same configuration as the display device 1 according to the above-described embodiment 1. For example, also in this embodiment, in the second display region A2, the electrode centers of the pixel electrodes of the light-emitting elements 21 and 23 are offset from the intersection point P. Therefore, the display device 1 according to this embodiment improves the display quality for the reasons described above, while reducing interference between diffracted light of the imaging light LT taken into the camera unit CU from the second display region A2, particularly the light-transmitting region A4, and reducing degradation in the quality of imaging by the camera unit CU.

[0099] [Embodiment 4] <Periodic Arrangement of Pixel Electrodes of Red Light-Emitting Elements> Fig. 7 is a further enlarged view showing the vicinity of the boundary between the first display region A1 and the third display region A3 and the vicinity of the boundary between the second display region A2 and the third display region A3 of the display device 1 according to this embodiment. In particular, Fig. 7 is a view showing positions corresponding to the schematic enlarged view shown in Fig. 1.

[0100] The display device 1 according to this embodiment differs from the display device 1 according to the previous embodiment in that the electrode centers of the light-emitting elements 23 in the second display area A2 coincide with the intersection point P. In other words, the center of the electrode 23E according to this embodiment coincides with the intersection point P. Furthermore, the center of the light-emitting area 23L according to this embodiment may coincide with the intersection point P.

[0101] Therefore, the display device 1 according to this embodiment reduces the difference between the arrangement pattern of the light-emitting elements 13 in the first display area A1 and the arrangement pattern of the light-emitting elements 23 in the second display area A2. Therefore, the display device 1 according to this embodiment further reduces the difference in the display pattern between the first display area A1 and the second display area A2, thereby further improving the display quality. In particular, when the light-emitting elements 13 and the light-emitting elements 23 emit red light, which is relatively more visible than blue light, the display device 1 according to this embodiment more efficiently achieves the above-mentioned effects.

[0102] On the other hand, except for the above points, the display device 1 according to this embodiment has the same configuration as the display device 1 according to the above-described embodiment 1. For example, also in this embodiment, in the second display region A2, the electrode centers of the pixel electrodes of the light-emitting elements 21 are offset from the intersection point P. Therefore, the display device 1 according to this embodiment improves the display quality for the reasons described above, while reducing interference between diffracted light of the imaging light LT taken into the camera unit CU from the second display region A2, particularly the light-transmitting region A4, and reducing degradation in the quality of imaging by the camera unit CU.

[0103] [Embodiment 5] <Periodic Arrangement of Light-Emitting Regions> Fig. 8 is a further enlarged view showing the vicinity of the boundary between the first display region A1 and the third display region A3 and the vicinity of the boundary between the second display region A2 and the third display region A3 of the display device 1 according to this embodiment. In particular, Fig. 8 is a view showing positions corresponding to the schematic enlarged view shown in Fig. 1.

[0104] The display device 1 according to this embodiment differs in configuration from the display device 1 according to the previous embodiment only in that the center of each light-emitting region in the second display region A2 coincides with the intersection point P. For example, the electrode center of the electrode 21E of each light-emitting element 21 is offset from the intersection point P, while the center of the light-emitting region 21L of each light-emitting element 21 coincides with the intersection point P. Furthermore, the electrode centers of the electrode 22E of each light-emitting element 22 and the electrode 23E of each light-emitting element 23 may be offset from the intersection point P, and the centers of the light-emitting region 22L of each light-emitting element 22 and the light-emitting region 23L of each light-emitting element 23 may coincide with the intersection point P.

[0105] With the above configuration, the display device 1 according to this embodiment can reduce the periodicity of the presence or absence of pixel electrodes in the second display area A2, while reducing the difference in the formation pattern of the light-emitting areas of each light-emitting element between the first display area A1 and the second display area A2. Therefore, the display device 1 according to this embodiment can improve the display quality of the display unit DA while reducing the degradation of the quality of images captured by the camera unit CU.
