[Modes for carrying out the invention] 【0008】 [Embodiment 1] <Overview of the display device> Figure 2 is a schematic plan view of the display device 1. The display device 1 comprises a display unit DA and a frame unit NA formed around the outer periphery of the display unit DA. The display device 1 displays information on the display unit DA by controlling the light emission from each of the multiple light-emitting elements formed on the display unit DA, which will be described later. Drivers for driving each of the multiple 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 top surface, which is the light-emitting surface of the display unit DA of the display device 1. Furthermore, in this specification, as shown in Figure 2, in a plan view of the display device 1, the direction from the top to the bottom of the display device 1 is defined as the first direction D1, and the direction from the left to the right of the display device 1 is defined as the second direction D2. Hereafter, in each drawing of this specification except for Figure 4, the first direction D1 is defined as the direction from the top to the bottom of the paper, and the second direction D2 is defined as the direction from the left to the right of the paper. 【0010】 The display device 1 according to this embodiment includes, for example, light-emitting elements 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 for a 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 controls the emission of light from each light-emitting element by driving each pixel electrode based on a signal input from the driver of the frame unit NA, thereby performing display. 【0011】 Hereafter, 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 light-transmitting electrode that transmits visible light. Furthermore, each pixel electrode in the display unit DA is the anode of the light-emitting element, and the common electrode is the 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 comprises 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 inside the display unit DA beyond the first display area A1. Furthermore, the second display area A2 is formed inside the display unit DA beyond the third display area A3. For example, the second display area A2 has a substantially circular shape in a plan view of the display device 1. In this case, the third display area A3 is located, for example, between the first display area A1 and the second display area A2, and has a ring shape with substantially the same width in a plan view of the display device 1. 【0013】 <1st 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, it is a diagram showing the display unit DA enlarged with respect to 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, it is a diagram showing a further enlarged view 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】 In FIG. 3, only the pixel electrodes, which will be described later, among each light-emitting element are extracted and shown. In other words, in FIG. 3, each pixel electrode is shown through the functional layer formed for each pixel electrode and the common electrode formed in common for a plurality of pixel electrodes. Further, in FIG. 1, only one of each pixel electrode, one of the transparent wirings 46 electrically connected to the electrode 21E, which will be described later, and one of the pixel circuits 21D driving the electrode 21E are extracted and shown. 【0015】 As shown in FIG. 3, the first display area A1 includes, for example, a plurality of light-emitting elements 11 as the first light-emitting element, 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】 Each of the light-emitting elements 11, light-emitting elements 12, and light-emitting elements 13 includes, as electrodes, an electrode 11E, an electrode 12E, and an electrode 13E. Each of the electrode 11E, electrode 12E, and electrode 13E is a pixel electrode formed for each sub-pixel of the display unit DA. Here, as will be described later, the display device 1 includes a functional layer of each light-emitting element formed at a position overlapping each of the electrode 11E, electrode 12E, and electrode 13E in a plan view of the display device 1, and a common electrode common to each pixel electrode. Therefore, as shown in FIG. 1, in the first display area A1, light-emitting regions 11L, light-emitting regions 12L, and light-emitting regions 13L are formed at positions overlapping each of the electrode 11E, electrode 12E, and electrode 13E in a plan view of the display device 1. 【0017】 Here, in the present embodiment, as shown in FIG. 1, in the display unit DA of the display device 1, a virtual regular lattice pattern including a plurality of first lattice lines GL1 along the first direction D1 and a plurality of second lattice lines GL2 along the second direction D2 is formed. Each first lattice line GL1 is formed at a substantially constant interval in the second direction D2, and each second lattice line GL2 is formed at a substantially constant interval in the first direction D1. In the present embodiment, as shown in FIG. 1, at each intersection position of the first lattice line GL1 and the second lattice line GL2 in the display unit DA of the display device 1, an intersection point P of the regular lattice pattern is virtually formed. 【0018】 In the present embodiment, each light-emitting element in the first display area A1 is formed such that the electrode center of each pixel electrode coincides with the intersection point P of the virtual regular lattice pattern. In other words, in the plan view of the display device 1, the electrode centers of the electrode 11E, the electrode 12E, and the electrode 13E are formed at positions overlapping with any one of the plurality of intersection points P. Therefore, each of the light-emitting elements 11, the light-emitting element 12, and the light-emitting element 13 is arranged along the first direction D1 and the second direction D2. 【0019】 For example, let the distance between two points of two adjacent intersection points P be the distance LP. In this case, each electrode 11E is formed such that the electrode centers are separated from each other by twice the distance LP in each of the first direction D1 and the second direction D2 with respect to adjacent electrodes 11E. Also, each electrode 12E is formed such that the electrode centers are separated from each other by twice the distance LP in one of the first direction D1 and the second direction D2 with respect to adjacent electrodes 12E. Further, each electrode 13E is formed in the same manner as each electrode 11E, such that the electrode centers are separated from each other by twice the distance LP in each of the first direction D1 and the second direction D2 with respect to adjacent electrodes 13E. Incidentally, each electrode 12E is formed such that the electrode centers are separated from each other by the distance LP in each of the first direction D1 and the second direction D2 with respect to adjacent electrodes 11E and electrodes 13E. 【0020】 Therefore, in the first display area A1, the distance between electrodes 11E and 12E that are close to each other is the same. Similarly, in the first display area A1, the distance between electrodes 12E and 13E that are close to each other is the same, and the distance between electrodes 11E and 13E that are close to each other is the same. 【0021】 Electrodes 11E and 13E may, for example, have a square shape in a plan view of the display device 1. In this case, the electrode centers of electrodes 11E and 13E may be the intersections of two diagonals. Electrode 12E may, for example, have a rounded rectangle formed by connecting a pair of opposite straight lines with a curve in a plan view of the display device 1. In a plan view of the display device 1, one of two adjacent electrodes 12E may have its 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 its longitudinal and short directions. 【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 similar shape to each of the electrodes 11E, 12E, and 13E. In this case, in a plan view of the display device 1, the centers of each of the light-emitting regions 11L, 12L, and 13L may coincide with the centers of each of the electrodes 11E, 12E, and 13E. 【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, the light-emitting element 11 may emit light of a first color, the light-emitting element 12 may emit light of a second color, and the 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, the light-emitting element 11 may be a blue light-emitting element that emits blue light, the light-emitting element 12 may be a green light-emitting element that emits green light, and the 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 an emission center wavelength in the wavelength band of 380 nm to 500 nm. Green light refers to light having an emission center wavelength in the wavelength band of over 500 nm and up to 600 nm. Red light refers to light having an emission center wavelength in the wavelength band of over 600 nm and up to 780 nm. 【0026】 The first display area A1, for example, has a pixel circuit that drives a pixel electrode for each light-emitting element. Each pixel circuit may drive each pixel electrode and control the light emission from each light-emitting element based on a signal transmitted from the driver of the frame portion NA. Each pixel circuit may include a thin-film transistor formed by a method described later. 【0027】 For example, the display unit DA may have a plurality of first signal lines extending substantially vertically and a plurality of second signal lines extending substantially horizontally and a substantially horizontally. Signals from the driver of the frame unit NA may be applied to each of the first signal lines and the second signal lines. Here, in the first display area A1, in a plan view of the display device 1, each of the first signal lines and each of the second signal lines may overlap with each of the first grid lines GL1 and each of the second grid lines GL2. In other words, in the first display area A1, in a plan view of the display device 1, the intersections of each of the first grid lines GL1 and each of the second grid lines GL2 may coincide with each intersection point P. In this case, the display device 1 can arrange each pixel circuit that drives each light-emitting element in the first display area A1 near each light-emitting element, reducing the need to form wiring and the like. Each pixel circuit may drive each light-emitting element in accordance with the signals from the corresponding first signal lines and second signal lines. 【0028】 In this embodiment, a set containing at least one light-emitting element 11, one light-emitting element 12, and one light-emitting element 13 may be considered as a pixel in the first display area A1. For example, the first display area A1 may have multiple pixels, each containing one light-emitting element 11, two light-emitting elements 12, and one light-emitting element 13. In this case, the pixel electrodes of two light-emitting elements 12 included in the same pixel may be short-circuited and 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, multiple light-emitting elements 21 as the second light-emitting element, multiple light-emitting elements 22 as the fourth light-emitting element, and multiple light-emitting elements 23 as the fifth light-emitting element. 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 position and shape. 【0030】 For example, each of the light-emitting elements 21, 22, and 23 is provided with electrodes 21E, 22E, and 23E, respectively. Each of electrodes 21E, 22E, and 23E is a pixel electrode formed for each subpixel of the display unit DA. Here, as will be described later, the display device 1 includes a functional layer for each light-emitting element formed at a position overlapping with each of electrodes 21E, 22E, and 23E in a plan view of the display device 1, and a common electrode common to each pixel electrode. Therefore, as shown in Figure 1, in the second display area A2, light-emitting areas 21L, 22L, and 23L are formed at positions overlapping with each of electrodes 21E, 22E, and 23E in a plan view of the display device 1. 【0031】 In this embodiment, each light-emitting element in the second display area A2 is formed such that the electrode center of each pixel electrode is offset 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 area A2 are formed at positions offset from the intersection point P. 【0032】 For example, in this embodiment, the light-emitting element 21 may emit a first color of light, the light-emitting element 22 may emit a second color of light, and the light-emitting element 23 may emit a third color of light. 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 containing at least one each of the light-emitting elements 21, 22, and 23 in the second display area A2 may be considered as a pixel in the second display area A2. For example, the second display area A2 may have multiple pixels, each containing 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 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 sensitivity to green light than to blue and red light, and furthermore, it has a higher sensitivity to red light than to blue light. Therefore, when light-emitting element 21 emits blue light, light-emitting element 22 emits green light, and light-emitting element 23 emits red light, the display device 1 can improve its apparent resolution by providing more light-emitting elements 22 than other light-emitting elements of different colors. In addition, by reducing the area of ​​the light-emitting regions 21L, 23L, and 22L in that 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 electrodes, the proportion of the area of ​​the light-transmitting region A4 in the second display region A2 can be increased. 【0036】 <Third display area> The third display area A3 includes, for example, multiple of the aforementioned light-emitting elements 21, 22, and 23. Each of the light-emitting elements 21, 22, and 23 in the third display area A3 may have the same configuration as each of the light-emitting elements 21, 22, and 23 in the second display area A2, except for their relative positions. 【0037】 Each light-emitting element in the third display area A3 is formed such that the electrode center of its 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 area A3 are formed to coincide with one of the multiple intersection points P. Therefore, each of the light-emitting elements 21, 22, and 23 in the third display area 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 area A3 further includes a pixel circuit for driving each light-emitting element in the second display area A2. In other words, the pixel circuit for driving each light-emitting element in the second display area A2 is formed around the second display area A2 in a plan view of the display device 1. For example, as shown in Figure 1, the third display area A3 includes a pixel circuit 21D for driving the light-emitting element 21 in the second display area A2. For example, the pixel circuit 21D drives the light-emitting element 21 in the second display area A2 via a transparent wiring 46, which will be described later. 【0040】 Furthermore, the third display area A3 may include, in addition to the pixel circuit 21D shown in Figure 1, pixel circuits for driving the light-emitting elements 22 and 23 in the second display area A2, respectively. Also, the third display area A3 may include pixel circuits for driving each of the light-emitting elements in the third display area 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 Figure 4. Figure 4 is a schematic side cross-sectional view showing an enlarged view of the side cross-section of the display device 1 in a plane substantially perpendicular to the display surface, near the second display area A2 and the third display area A3. 【0042】 The display device 1 includes a light-transmitting substrate 31, which may include a glass substrate or a film substrate. The display device 1 also includes, in this order, a first inorganic interlayer 32, a second inorganic interlayer 33, a third inorganic interlayer 34, a first organic interlayer 35, a second organic interlayer 36, a third organic interlayer 37, and a fourth organic interlayer 38, all of which are light-transmitting, on the substrate 31. The substrate 31, each inorganic interlayer, and each organic interlayer may be formed in a display section DA including a first display area A1, a second display area A2, and a third display area 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 oxide inorganic film by 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 a light-transmitting organic coating film such as polyimide by a coating method or a photolithography method. The display device 1 is further provided with a common electrode 39 formed on the upper surface of the fourth organic interlayer film 38, which is common to the pixel electrodes of the display unit DA. 【0044】 In this embodiment, each pixel electrode in the second display area A2 and the third display area 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 area A2 and the third display area A3, a functional layer 21F including a light-emitting layer is formed between each electrode 21E and the common electrode 39. As a result, a light-emitting element 21 is formed in the second display area A2 and the third display area A3 by each electrode 21E, each functional layer 21F, and the common electrode 39. 【0045】 Furthermore, each pixel electrode in the first display area A1 may be formed between the third organic interlayer film 37 and the fourth organic interlayer film 38. For example, in the first display area A1, a functional layer including a light-emitting layer may be formed between each pixel electrode and the common electrode 39. As a result, a light-emitting element may be formed in the first display area A1 by each pixel electrode, each functional layer, and the common electrode 39. 【0046】 If 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 that 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 as the light-emitting material, in other words, quantum dots. 【0047】 The display device 1 drives the light-emitting element 21 to emit light LR of the first color from the light-emitting layer of the functional layer 21F. This enables display in the display unit DA, which includes the second display area A2 and the third display area A3. 【0048】 Furthermore, in the third display area A3, the display device 1 comprises, 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 via a contact hole 46C formed in the second organic interlayer film 36. The transparent wiring 46 is also routed to the second display area A2 and electrically connected to the electrode 21E via 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, conductive films containing a metal film that have light reflectivity. The transparent wiring 46 is a transparent member that is light-transmitting and electrically conductive. Each pixel circuit in the third display area 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】 Furthermore, the pixel circuits that drive each light-emitting element in the third display area A3 may be formed by forming thin-film transistors in the third display area A3, similar to the pixel circuits that drive each light-emitting element in the second display area A2. Also, the pixel circuits that drive each light-emitting element in the first display area A1 may be formed by forming thin-film transistors in the first display area A1. For this reason, the first conductive film 41, semiconductor film 42, second conductive film 43, third conductive film 44, and fourth conductive film 45 may also be formed in the first display area A1. 【0052】 <Location of light-emitting region formation> As shown in Figure 4, in this embodiment, the functional layers of each light-emitting element in the display unit DA, which includes the first display area A1, the second display area A2, and the third display area A3, are formed in openings formed in the fourth organic interlayer film 38. For example, the functional layer may be formed by forming the substrate 31 to the fourth organic interlayer film 38, then forming an opening in the fourth organic interlayer film 38 at a position that overlaps with each pixel electrode in a plan view of the display device 1, and forming a layer containing the material of the functional layer in the opening. 【0053】 In this case, the opening of the fourth organic interlayer film 38 in the second display area A2 may be shifted in position to match the displacement of the pixel electrode corresponding to the opening. In other words, in a plan view of the display device 1, the center of the opening of the fourth organic interlayer film 38 in the second display area A2 may be offset from the intersection point P. This makes it possible to shift the center of the light-emitting area of ​​each light-emitting element in the second display area A2 and the intersection point P in accordance with the displacement between the electrode center of the pixel electrode of each light-emitting element in the second display area A2 and the intersection point P. 【0054】 For example, the formation pattern of the functional layer material in the second display area A2 may be the same as the formation pattern of the functional layer material in the first display area A1 and the third display area A3. In this case, the positions of the openings of the fourth organic interlayer film 38 in the second display area A2 should be shifted so that, in a plan view of the display device 1, the positions of the openings of the fourth organic interlayer film 38 in the second display area A2 are included in the formation positions of each functional layer in the second display area A2. 【0055】 For example, in a plan view of the display device 1, the pixel electrodes of each light-emitting element in the second display area A2 may overlap with the intersection point P. Also, the magnitude of the displacement between the electrode center of each pixel electrode of each light-emitting element in the second display area A2 and each intersection point P may be 1 / 2 or less of the diameter of the light-emitting area of ​​each light-emitting element in the second display area A2. This reduces the possibility that a functional layer will not be formed in a part of the opening of the fourth organic interlayer film 38 in the second display area A2, even by the method described above. 【0056】 For example, the functional layer may be formed by vapor deposition using a vapor deposition mask such as a metal mask having multiple openings. In this case, the shape and arrangement pattern of the openings in the vapor deposition mask may be the same at positions corresponding to the first display area A1 and the third display area A3 and at positions corresponding to the second display area A2. Even in this case, the formation position of each light-emitting area in the second display area A2 can be controlled by controlling the position of each opening of the fourth organic interlayer film 38 in the second display area A2 in a plan view of the display device 1. 【0057】 Furthermore, for example, the functional layer may be formed by an inkjet method in which the material of the functional layer is dropped onto the openings of the fourth organic interlayer film 38. In this case, the position where the material of the functional layer is dropped may be a position corresponding to each intersection P in any of the first display area A1, the second display area A2, and the third display area A3. In this case, as long as each opening of the fourth organic interlayer film 38 in the second display area A2 and the intersection P overlap in a plan view of the display device 1, it is possible to reduce the possibility of the functional layer not being formed on a portion of the openings of the fourth organic interlayer film 38 in the second display area A2. 【0058】 <Capturing imaging light into the camera> In the second display area A2, the display device 1 further includes a camera unit CU on the side of the substrate 31 opposite to the light-emitting element 21, which is a camera equipped with an image sensor and the like. Imaging light LT incident from the display surface side of the display device 1 is incident on the camera unit CU. In particular, the second display area A2 has a light-transmitting member formed therein, including transparent wiring 46, except for each pixel electrode. Therefore, a light-transmitting region A4 is formed between each pixel electrode in the second display area A2, through which imaging light LT is transmitted 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 image the display surface side of the substrate 31 using the camera unit CU. Thus, the display device 1 can, for example, display an image on the OLED panel while simultaneously imaging the display surface side of the OLED panel using the camera unit CU. The display device 1 may also use the camera unit CU to image the back side of the display device 1, that is, the side opposite to the display surface of the substrate 31. 【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 area A2. Therefore, the imaging light LT captured by the camera unit CU passes through the gaps between each pixel electrode in the second display area A2. 【0061】 <Interference of diffracted light from imaging light> Here, we consider the influence that each pixel electrode in the second display area A2 has on the imaging light LT taken into the camera unit CU. 【0062】 For example, in a plan view of the display device 1, suppose that the electrode centers of each pixel electrode in the second display area A2 coincide on a certain intersection P, just like the electrode centers of each pixel electrode in the first display area A1 and the third display area A3. In this case, the positional relationship between each of the pixel electrodes in the second display area A2 and other adjacent pixel electrodes will be approximately the same. Therefore, in any direction of the display surface of the display device 1, there will be a periodic presence of areas in the second display area A2 where pixel electrodes are formed and areas where pixel electrode wiring is not formed. 【0063】 When imaging light LT is incident on the light-transmitting region A4, it diffracts as it passes through each of the pixel electrodes, and multiple diffracted rays may interfere with each other. Here, if the electrode centers of each pixel electrode in the second display region A2 lie on the intersection point P, the pixel electrodes in the light-transmitting region A4 are arranged periodically, causing each pixel electrode to behave like a diffraction grating, which may intensify the interference of the diffracted rays described above. 【0064】 If multiple imaging light sources (LT) captured by the camera unit (CU) interfere with each other, it can lead to enhancement or attenuation of light of specific wavelengths, potentially degrading the image quality captured by the camera unit (CU). 【0065】 In this embodiment, each light-emitting element in the second display area A2 is formed such that the electrode center of each pixel electrode is offset from the intersection point P. As a result, the periodicity of the presence or absence of pixel electrodes in the light-transmitting area A4 in any direction on the display surface is reduced. Therefore, the display device 1 according to this embodiment can reduce the interference between diffracted light rays of the imaging light LT that passes through each of the pixel electrodes. Thus, the display device 1 reduces the interference between diffracted light rays of the imaging light LT taken into the camera unit CU from the second display area A2, particularly the light-transmitting area A4, and reduces the degradation of imaging quality by the camera unit CU. 【0066】 <Addendum> In this embodiment, each light-emitting element in the second display area A2 may be formed such that, for example, the electrode center of each pixel electrode is offset 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 of each light-emitting element in the second display area A2. 【0067】 In this embodiment, the direction and distance of the deviation from the intersection point P of the electrode centers of each light-emitting element in the second display area A2 may be random. For example, in this embodiment, the direction and distance of the deviation from the intersection point P of each pixel electrode in the second display area A2 may be determined according to a separately generated random number table. 【0068】 With the above configuration, the periodicity of the arrangement position of each pixel electrode in the second display area A2 is further reduced compared to the case where the displacement is determined according to a predetermined rule. Therefore, with the above configuration, the display device 1 can further reduce interference between diffracted light rays of the imaging light LT taken in from the light-transmitting area A4 into the camera unit CU. 【0069】 In this embodiment, in a plan view of the display device 1, electrodes 21E, 22E, and 23E may each be formed at a position that coincides with the intersection point P. With the above configuration, the display device 1 reduces the excessive deviation between the center of the light-emitting area of ​​each light-emitting element in the second display area A2 and the intersection point P, thereby reducing the deterioration of the display quality in the second display area A2. 【0070】 For example, in this embodiment, a random number table of XY coordinates may be set for each light-emitting element in the second display area A2, with equal probability distribution within a range of 1 / 2 of the diameter of the light-emitting area. In this embodiment, the direction and distance of the deviation from the intersection point P of the electrode centers of each light-emitting element in the second display area A2 may be determined according to the random number table. 【0071】 In this case, the magnitude of the deviation from the intersection point P of the electrode centers of each light-emitting element in the second display area A2 is less than or equal to half the diameter of each light-emitting area. With the above configuration, the display device 1 reduces the likelihood of the deviation between the center of the light-emitting area of ​​each light-emitting element and the intersection point P becoming too large in the second display area A2, thereby reducing the deterioration of the display quality in the second display area A2. 【0072】 The random number table may be represented in polar form of the argument angle θ and the deviation r. The random number table may be set for the entire area of ​​the second display area A2. Alternatively, the second display area A2 may be divided into multiple sub-regions, and a separate random number table may be set for each sub-region, or the same random number table may be set for each sub-region. 【0073】 Therefore, in the second display area A2, the distances between electrodes 21E and 22E that are close to each other may differ. Similarly, in the second display area A2, the distances between electrodes 22E and 23E that are close to each other may differ, and the distances between electrodes 21E and 23E that are close to each other may differ. 【0074】 However, the electrode centers of some of the pixel electrodes in the second display area 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 area A2 may include a light-emitting element 21 whose electrode centers are offset from the intersection point P, while also including a third light-emitting element 21 whose electrode centers coincide with the intersection point P. 【0075】 In the above configuration, since some electrode centers of the electrodes 21E of the light-emitting element 21 in the second display area A2 are offset from the intersection point P, the display device 1 can reduce the periodicity of the presence or absence of pixel electrodes in the second display area A2. On the other hand, in the above configuration, some electrode centers of the electrodes 21E of the light-emitting element 21 in the second display area A2 coincide with the intersection point 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 area A1 and the arrangement pattern of the light-emitting elements 22 in the second display area A2. Thus, the display device 1 according to this embodiment reduces the difference in display patterns between the first display area A1 and the second display area A2, and improves the display quality. 【0076】 In this embodiment, the multiple intersection points P are located along the first direction D1 and the second direction D2. Furthermore, the electrode centers of the pixel electrodes of each light-emitting element in the second display area A2 are offset from the intersection points P in at least one of the first direction D1 and the second direction D2. This allows the display device 1 to reliably generate the offset of the electrode centers of the pixel electrodes of each light-emitting element in the second display area A2 with respect to the intersection points P using a simple configuration. In particular, the offset of the electrode centers of each light-emitting element in the second display area A2 described above can be easily achieved by setting the offset according to a 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 area A2 can be achieved with a simple design. 【0077】 In this embodiment, each of the electrodes 21E, 22E, and 23E may have a circular shape in a plan view of the display device 1. In this case, the center of each electrode 21E, 22E, and 23E may be the center of the circle. In other words, each of the electrodes 21E, 22E, and 23E may have a different shape from each of the electrodes 11E, 12E, and 13E. In other words, the electrode shapes of each light-emitting element may be different between the first display area A1 and the second display area A2. With the above configuration, the display device 1 can further reduce interference of imaging light in the light-transmitting area A4 near the boundary with the first display area A1 and between the pixel electrodes of the light-emitting elements in the first display area A1 and the pixel electrodes of the light-emitting elements in the second display area A2. 【0078】 Furthermore, the respective electrode areas of electrode 21E, electrode 22E, and electrode 23E may be smaller than the respective electrode areas of electrode 11E, electrode 12E, and electrode 13E. 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 area A2 may be smaller than the size of the pixel electrode of each light-emitting element in the first display area A1. With the above configuration, the display device 1 can reduce the proportion of the area occupied by the pixel electrodes of each light-emitting element in a plan view in the second display area A2 compared to the first display area A1. Therefore, the display device 1 can more easily secure the area of ​​the light-transmitting area A4 in the second display area A2. 【0079】 Furthermore, in a plan view of the display device 1, the size of the pixel electrode of each light-emitting element in the third display area A3 may be smaller than the size of the pixel electrode of each light-emitting element in the first display area A1. This reduces the proportion of the area occupied by each pixel electrode in the third display area A3. Consequently, the display device 1 can more easily form pixel circuits in the third display area A3 to drive each light-emitting element in both the second display area A2 and the third display area 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 coincide with the electrode 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 this embodiment, in at least one pair of adjacent light-emitting elements 21 and 22, the directions of displacement of the electrode centers from the intersection point P may be different. In other words, in adjacent electrodes 21E and 22E, the direction in which the electrode center of electrode 21E is displaced from the intersection point P and the direction in which the electrode center of electrode 22E is displaced from the intersection point P may be different. 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 of displacement of the electrode centers from the intersection point P may be different. In other words, in adjacent electrodes 21E and 23E, the direction in which the electrode center of electrode 21E is displaced from the intersection point P and the direction in which the electrode center of electrode 23E is displaced from the intersection point P may be different. With the above configuration, the display device 1 can further reduce interference of imaging light between the light-emitting elements 21 and 23. 【0083】 In the display unit DA, the pixel electrodes of each light-emitting element are light-reflecting electrodes. Therefore, the display device 1 can more efficiently increase the intensity of light emitted from each light-emitting element. If the pixel electrodes of each light-emitting element in the display unit DA are anodes, the display device 1 can further improve the freedom of the material of the pixel electrodes to make them light-reflecting electrodes. On the other hand, in the second display area A2, a light-transmitting area A4 is formed, so the display device 1 can ensure the intensity of light emitted from each light-emitting element while enabling the acquisition of imaging light into the camera unit CU. 【0084】 In this embodiment, a transparent wiring 46 is formed in the second display area A2 to electrically connect the pixel electrode of any light-emitting element in the second display area A2 to any pixel circuit in the third display area A3. Therefore, the display device 1 can form a pixel circuit for driving a light-emitting element having a pixel electrode connected to the transparent wiring 46 at a position away from the light-emitting element. Furthermore, since the transparent wiring 46 is light-transmitting, the display device 1 can reduce the obstruction of the camera unit CU from receiving imaging light due to the transparent wiring 46, even when the transparent wiring 46 is formed in the light-transmitting area A4. 【0085】 In particular, the pixel circuits that drive each light-emitting element in the second display area A2 are located in the third display area A3, which is situated 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 obstruction of the acquisition of imaging light into the camera unit CU by the pixel circuits that drive each light-emitting element in the second display area A2. 【0086】 [Embodiment 2] <Gradual reduction of pixel electrodes> Figure 5 is a more enlarged view 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, of the display device 1 according to this embodiment. In particular, Figure 5 shows the position corresponding to the schematic enlarged view shown in Figure 1. 【0087】 The display device 1 according to this embodiment differs from the display device 1 according to the previous embodiment in that the pixel electrodes and light-emitting regions of each light-emitting element in the second display area A2 and the third display area A3 are different. 【0088】 In this embodiment Okeru In the second display area A2 and the third display area A3, the size of the electrodes 21E of the light-emitting element 21 varies depending on the distance from the center of the second display area A2. In particular, in this embodiment, the size of the electrodes 21E in the second display area A2 and the third display area A3 decreases as you approach the center of the second display area A2. On the other hand, the size of the light-emitting area 21L in the second display area A2 and the third display area A3 may be constant regardless of the distance from the center of the second display area A2. 【0089】 Similarly, in this embodiment Okeru In the second display area A2 and the third display area A3, the size of the electrode 22E of the light-emitting element 22 and the size of the electrode 22E of the light-emitting element 22 may differ depending on the distance from the center of the second display area A2. In particular, in this embodiment, the size of the electrode 22E and electrode 23E in the second display area A2 and the third display area A3 may decrease as they approach the center of the second display area A2. Also, the size of the light-emitting area 22L and light-emitting area 23L in the second display area A2 and the third display area A3 may be constant regardless of the distance from the center of the second display area A2. 【0090】 Except for the configuration described above, 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 area 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 rays of the imaging light LT taken into the camera unit CU from the second display area A2, particularly the light-transmitting area A4, and reduces the degradation of imaging quality by the camera unit CU. 【0091】 Furthermore, in this embodiment, since the size of the electrode 21E of the light-emitting element 21 differs according to 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 area of ​​each light-emitting element may be the same in the second display area A2 and the third display area A3, depending on the distance from the center of the second display area A2. On the other hand, the size of the light-emitting area of ​​each light-emitting element may differ in the second display area A2 and the third display area A3, depending on the distance from the center of the second display area A2. For example, in the second display area A2 and the third display area A3, the smaller the pixel electrode of each light-emitting element, the smaller the size of the light-emitting area of ​​each light-emitting element may be. 【0093】 In this case, if there is a difference in the area of ​​the light-emitting region of multiple light-emitting elements in the display device 1, a difference will also occur in the drive current value required to obtain the same brightness for those multiple light-emitting elements. In particular, the smaller the light-emitting region of a light-emitting element in the display device 1, the greater the drive current value required to obtain the same brightness for that light-emitting element tends to be. Also, generally, the brightness degradation of a light-emitting element tends to progress faster as the drive current value increases. Therefore, if there is a difference in the area of ​​the light-emitting region of multiple light-emitting elements depending on the position of the display unit DA in the display device 1, differences in the brightness degradation of those multiple light-emitting elements are likely to occur. 【0094】 For example, in this embodiment, the size of the electrode 21E gradually changes according to the distance from the center of the second display area A2, while the size of the light-emitting area 21L remains the same regardless of the distance from the center of the second display area A2. In this case, the display device 1 according to this embodiment is at the position of the display unit DA of This reduces abrupt changes in the brightness degradation of each light-emitting element due to changes, thereby improving display quality. In particular, the display device 1 according to this embodiment reduces abrupt changes in the brightness degradation of each light-emitting element at the boundaries of the first display area A1, the second display area A2, and the third display area A3, thereby reducing the visibility of these boundaries. 【0095】 [Embodiment 3] <Periodic arrangement of pixel electrodes in a green light-emitting element> Figure 6 is a more enlarged view 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 of the display device 1 according to this embodiment. In particular, Figure 6 shows the position corresponding to the schematic enlarged view shown in Figure 1. 【0096】 The display device 1 according to this embodiment differs from the display device 1 according to the previously described embodiment 1 in that the electrode centers of each light-emitting element 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. Also, 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. Consequently, the display device 1 according to this embodiment reduces the difference in display patterns between the first display area A1 and the second display area A2, thereby improving display quality. In particular, when the light-emitting elements 12 and 22 emit green light, which is relatively easier to see than blue light and red light, the display device 1 according to this embodiment achieves the above effect more efficiently. 【0098】 On the other hand, except for the points mentioned above, the display device 1 according to this embodiment has the same configuration as the display device 1 according to the previously described embodiment 1. For example, in this embodiment as well, in the second display area A2, the electrode centers of the respective pixel electrodes of the light-emitting element 21 and light-emitting element 23 are offset from the intersection point P. For this reason, the display device 1 according to this embodiment improves the display quality for the reasons mentioned above, while reducing interference between diffracted light rays of the imaging light LT taken into the camera unit CU from the second display area A2, particularly the light-transmitting area A4, thereby reducing the degradation of imaging quality by the camera unit CU. 【0099】 [Embodiment 4] <Periodic arrangement of pixel electrodes in a red light-emitting element> Figure 7 is a more enlarged view 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, of the display device 1 according to this embodiment. In particular, Figure 7 shows the position corresponding to the schematic enlarged view shown in Figure 1. 【0100】 The display device 1 according to this embodiment differs from the display device 1 according to the previous embodiment in that the configuration of the electrodes of each light-emitting element 23 in the second display area A2 coincides with the intersection point P. In other words, the center of the electrode 23E according to this embodiment coincides with the intersection point P. Also, 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. Consequently, the display device 1 according to this embodiment further reduces the difference in display patterns between the first display area A1 and the second display area A2, and further improves the display quality. In particular, when the light-emitting elements 13 and 23 emit red light, which is relatively easier to see than blue light, the display device 1 according to this embodiment achieves the above effect more efficiently. 【0102】 On the other hand, except for the points mentioned above, the display device 1 according to this embodiment has the same configuration as the display device 1 according to the previously described embodiment 1. For example, in this embodiment as well, in the second display area A2, the electrode centers of each pixel electrode of the light-emitting element 21 are offset from the intersection point P. For this reason, the display device 1 according to this embodiment improves the display quality for the reasons mentioned above, while reducing interference between diffracted light rays of the imaging light LT taken into the camera unit CU from the second display area A2, particularly the light-transmitting area A4, thereby reducing the degradation of imaging quality by the camera unit CU. 【0103】 [Embodiment 5] <Periodic arrangement of the light-emitting region> Figure 8 is a more enlarged view 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 of the display device 1 according to this embodiment. In particular, Figure 8 shows the position corresponding to the schematic enlarged view shown in Figure 1. 【0104】 The display device 1 according to this embodiment differs 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. Also, 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 patterns of the light-emitting regions of each light-emitting element in the first display area A1 and the second display area A2. Therefore, the display device 1 according to this embodiment improves the display quality in the display unit DA while reducing the degradation of the image quality by the camera unit CU. 【0106】 This disclosure is not limited to the embodiments described above, and various modifications are possible within the scope of the claims.
