[0002] A display device is a device that displays images to provide visual information to a user. Among display devices, organic light-emitting diode (OLED) displays have recently attracted much attention.

[0003] The display device may include a first display area with high resolution and a second display area with a lower resolution than the first display area.

[0049] Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. The same reference numerals will be used for the same constituent elements in the drawings, and repeated descriptions of the same constituent elements will be omitted.

[0050] Figure 1 This is a plan view of a display device according to an embodiment of the present invention. Figure 2 It is along Figure 1 A cross-sectional view taken from the I-I' line.

[0051] Reference Figure 1 and Figure 2 The display device 10 may include a display panel 100, a flexible circuit board 20 connected to the display panel 100, and a driving device including a driving chip 30, etc.

[0052] The display panel 100 may include a display area DA for displaying images and a non-display area NA surrounding the display area DA. The display area DA may correspond to a screen, and the non-display area NA may correspond to a bezel. Light-emitting areas PX may be arranged in a matrix within the display area DA. Circuits and / or signal lines for generating and / or transmitting signals applied to the display area DA may be arranged within the non-display area NA.

[0053] Each of the light-emitting regions PX can be connected to scan lines, light-emitting control lines, data lines, driving voltage lines, etc. The light-emitting region PX can receive scan signals, light-emitting control signals, data signals, driving voltages, etc. from these signal lines.

[0054] The display area DA may include a first display area DA1 and a second display area DA2. The second display area DA2 may perform other functions besides displaying images. Therefore, the transmittance of the second display area DA2 may be higher than that of the first display area DA1. Here, transmittance may refer to the transmittance of light transmitted through the display panel 100. The light may be light of wavelengths other than visible light, for example, infrared light, but may also include visible light.

[0055] The ratio of the area occupied by the luminescent region PX in the second display area DA2 can be less than the ratio of the area occupied by the luminescent region PX in the first display area DA1. For example, the second display area DA2 may include the luminescent region PX and a transmission area, and the transmittance of the transmission area may be higher than the transmittance of the luminescent region PX. The luminescent region PX may be the smallest unit constituting the screen (i.e., displaying an image). Each of the luminescent regions PX can display a specific color (e.g., any one of red, green, and blue) with varying brightness according to the input image signal.

[0056] The driver chip 30 and the flexible circuit board 20 can be located in the non-display area NA of the display panel 100. The driver chip 30 can be mounted on the flexible circuit board 20 using a chip-on-film (COF) method. The driver chip 30 can be mounted on the flexible circuit board 20 and electrically connected to the display panel 100.

[0057] The flexible circuit board 20 may be a circuit board that supplies drive signals to the display device 10. The flexible circuit board 20 may include a timing controller and a power supply voltage generation unit. The timing controller can generate control signals for driving the display device 10. The power supply voltage generation unit can generate a power supply voltage.

[0058] The display area DA can display an image based on driving signals applied to multiple light-emitting region PX structures arranged on the substrate SUB. The light-emitting region PX structures can be arranged in a matrix along a first direction D1 and a second direction D2 orthogonal to the first direction D1.

[0059] The display panel 100 may include a substrate SUB, a barrier layer BRR, a buffer layer BFR, a transistor 200, an interlayer insulating layer 240, an insulating film 400, a pixel definition film 600, and a light-emitting diode 500.

[0060] A light-emitting region PX can be formed on the substrate SUB. The substrate SUB can be continuously arranged across the first display region DA1 and the second display region DA2.

[0061] The substrate SUB can be made of a variety of materials. For example, the substrate SUB can be made of glass with SiO2 as the main component. However, the substrate SUB is not limited to this and can also be made of plastic.

[0062] A barrier layer BRR may be located on the substrate SUB. The barrier layer BRR prevents external foreign matter from penetrating into the interior of the display device 10 through the substrate SUB. A buffer layer BFR may be located on the barrier layer BRR. The buffer layer BFR can flatten one surface of the substrate SUB or prevent impurities from diffusing.

[0063] Transistor 200 may be located on buffer layer BFR. Transistor 200 may include semiconductor layer 210, gate insulating film 220, gate electrode 230, source electrode 250, and drain electrode 260. Semiconductor layer 210 may include polycrystalline silicon, amorphous silicon, or oxide semiconductor.

[0064] A gate insulating film 220 may be located on the semiconductor layer 210. A gate electrode 230 may be located on the gate insulating film 220. The gate electrode 230 may be insulated from the semiconductor layer 210 by means of the gate insulating film 220. The gate insulating film 220 may be arranged to overlap the entire surface of the substrate SUB. The gate insulating film 220 may include materials such as silicon oxide (SiO2). x ), silicon nitride (SiN) x Inorganic insulating materials such as )

[0065] Interlayer insulating layer 240 may be located on gate electrode 230. Interlayer insulating layer 240 may include inorganic material. Source electrode 250 and drain electrode 260 of transistor 200, data lines, signal lines (not shown), etc., may be located on interlayer insulating layer 240. Each of source electrode 250 and drain electrode 260 may contact a region of semiconductor layer 210 through an opening in interlayer insulating layer 240 and may be electrically connected to semiconductor layer 210. For example, source electrode 250 and drain electrode 260 may contact the source region and drain region of semiconductor layer 210, respectively.

[0066] The insulating film 400 may be located on the interlayer insulating layer 240. To improve the luminous efficiency of the light-emitting layer 520 located on the insulating film 400, the insulating film 400 can eliminate step differences and flatten the surface. The insulating film 400 may overlap with and cover the transistor 200. As an example, the insulating film 400 may include an organic material. The organic material may include, but is not limited to, polyimide, polyamide, polyacrylate, unsaturated polyester, epoxy resin, phenolic resin, etc.

[0067] The insulating film 400 may include contact holes (CNTs). A contact hole (CNT) may refer to a portion of the insulating film 400 through which a portion of the insulating film 400 is removed. A pixel electrode 510 may be located on the insulating film 400. The pixel electrode 510 may overlap with the contact hole (CNT). The pixel electrode 510 may include a reflective conductive material, or it may include a semi-transparent conductive material, or it may include a transparent conductive material. As an example, the pixel electrode 510 may include a transparent conductive material such as indium tin oxide (ITO) or indium zinc oxide (IZO), and at least one metal such as lithium (Li), calcium (Ca), aluminum (Al), silver (Ag), magnesium (Mg), and gold (Au).

[0068] A pixel definition film 600 may be formed on the pixel electrode 510. The pixel definition film 600 may have an opening 610 overlapping with the pixel electrode 510. A light-emitting layer 520 may be formed in the opening 610. A common electrode 530 for transmitting a common voltage may be located on the light-emitting layer 520. The common electrode 530 may include a transparent conductive material such as indium tin oxide (ITO) or indium zinc oxide (IZO). The common electrode 530 may be formed to be transparent by stacking metals such as calcium (Ca), barium (Ba), magnesium (Mg), aluminum (Al), and silver (Ag).

[0069] The pixel electrode 510, the light-emitting layer 520, and the common electrode 530 can constitute a light-emitting diode 500. The pixel electrode 510 can be an anode, serving as a hole injection electrode, and the common electrode 530 can be a cathode, serving as an electron injection electrode. Conversely, the pixel electrode 510 can also be a cathode, and the common electrode 530 can also be an anode.

[0070] Figure 3 It is magnification Figure 1 An enlarged view of region A.

[0071] Reference Figure 1 and Figure 3 The display device 10 may include a first display area DA1 and a second display area DA2. The second display area DA2 may be located at the edge of the first display area DA1. That is, the second display area DA2 may be arranged around the first display area DA1. The second display area DA2 may be arranged in the form of a strip with a relatively thin width at the edge of the first display area DA1.

[0072] The second display area DA2 may have a shape that extends along the corners of the first display area DA1. The corners may refer to the four corners of the first display area DA1. Specifically, each of the four corners of the first display area DA1 may have a curved shape. Furthermore, since the second display area DA2 is located at the edge of the first display area DA1, each of the four corners of the second display area DA2 may also have a curved shape. However, when the boundary between the first display area DA1 and the second display area DA2 is magnified, the shape of the boundary between the first display area DA1 and the second display area DA2 may be stepped.

[0073] The first display area DA1 and the second display area DA2 may include multiple light-emitting areas PX. The size of the light-emitting area included in the first display area DA1 may be smaller than the size of the light-emitting area included in the second display area DA2. Based on the first display area DA1, red light-emitting areas R and blue light-emitting areas B may be alternately arranged in the first row 1N. In the second row 2N adjacent to the first row 1N, multiple green light-emitting areas G may be arranged at predetermined intervals. In the third row 3N adjacent to the second row 2N, blue light-emitting areas B and red light-emitting areas R may be alternately arranged, and in the fourth row 4N adjacent to the third row 3N, multiple green light-emitting areas G may be arranged at predetermined intervals. This arrangement of light-emitting areas may be repeated up to the Nth row.

[0074] At this point, the multiple red emitting areas R and multiple blue emitting areas B arranged in the first row 1N, and the multiple green emitting areas G arranged in the second row 2N, can be arranged in a staggered manner. Therefore, red emitting areas R and blue emitting areas B can be alternately arranged in the first column 1M. Multiple green emitting areas G can be arranged at predetermined intervals in the second column 2M adjacent to the first column 1M. Blue emitting areas B and red emitting areas R can be alternately arranged in the third column 3M adjacent to the second column 2M, and multiple green emitting areas G can be arranged at predetermined intervals in the fourth column 4M adjacent to the third column 3M. This arrangement of emitting areas can be repeated up to the Mth column.

[0075] The spacing between the red emitting regions R within the first display area DA1 along the first direction D1 and the second direction D2 can be substantially the same. Similarly, the spacing between the blue emitting regions B within the first display area DA1 along the first direction D1 and the second direction D2 can be substantially the same. Likewise, the spacing between the green emitting regions G within the first display area DA1 along the first direction D1 and the second direction D2 can be the same. In other words, the distance between emitting regions of the same color within the first display area DA1 can be constant.

[0076] Such an arrangement of luminescent areas can be called a pentile matrix. A rendering driver that uses shared adjacent luminescent areas to represent colors can be applied to this pentile matrix. Therefore, high resolution can be achieved using a smaller number of luminescent areas. Similarly, the pentile matrix structure can also be applied to the second display area DA2. However, embodiments of the invention are not limited to this; in another embodiment, the luminescent areas can be arranged in a striped shape or various other shapes.

[0077] The sizes of the red emitting regions R included in the first display area DA1 can be the same as each other. The sizes of the blue emitting regions B included in the first display area DA1 can be the same as each other. The sizes of the green emitting regions G included in the first display area DA1 can be the same as each other. Similarly, the sizes of each of the red emitting region R, blue emitting region B, and green emitting region G included in the second display area DA2 can be the same among emitting regions of the same color.

[0078] The sizes of the red emitting region R and the blue emitting region B, included in the first display area DA1 and the second display area DA2, can be larger than the size of the green emitting region G. The number of green emitting regions G can be greater than the number of red emitting regions R and the number of blue emitting regions B. The size of the red emitting region R can be larger than the size of the blue emitting region B. However, according to embodiments of the present invention, this is not limited to this; the size of the blue emitting region B can be larger than the size of the red emitting region R, or substantially the same as the size of the red emitting region R.

[0079] In one embodiment, the first display area DA1 and the second display area DA2 may include multiple light-emitting areas PX. For example, the first display area DA1 may include a first light-emitting area PX1 and a second light-emitting area PX2. The second display area DA2 may include a third light-emitting area PX3. The first light-emitting area PX1, the second light-emitting area PX2, and the third light-emitting area PX3 may emit a first color. The first color may be red. Since the red light-emitting area R is larger than the blue light-emitting area B and the green light-emitting area G, arranging the light-emitting areas based on the red light-emitting area R can more effectively prevent color mixing. However, in another embodiment, the first color may be blue or green.

[0080] The size of each light-emitting area included in the first display area DA1 can be smaller than the size of each light-emitting area included in the second display area DA2. Therefore, the size of the third light-emitting area PX3 can be larger than the sizes of the first light-emitting area PX1 and the second light-emitting area PX2.

[0081] The first luminescent region PX1 and the third luminescent region PX3 may be adjacent to each other along a first direction D1. The centers of the first luminescent region PX1 and the third luminescent region PX3 may be located on an axis extending along the first direction D1. The second display region DA2 may further include a fifth luminescent region PX5 separated from the third luminescent region PX3 along a third direction D3 opposite to the first direction D1. Similarly, the centers of the third luminescent region PX3 and the fifth luminescent region PX5 may be located on an axis extending along the first direction D1. In summary, the center of the red luminescent region R, which is adjacent to the centers of the first luminescent region PX1, the third luminescent region PX3, and the fifth luminescent region PX5 along the first direction D1 and the third third direction D3, may be located on an axis extending along the first direction D1.

[0082] The second luminescent region PX2 and the third luminescent region PX3 may be adjacent to each other along the second direction D2. The centers of the second luminescent region PX2 and the third luminescent region PX3 may be located on an axis extending along the second direction D2. The first display area DA1 may also include a sixth luminescent region PX6 separated from the second luminescent region PX2 along the second direction D2. Similarly, the centers of the second luminescent region PX2 and the sixth luminescent region PX6 may be located on an axis extending along the second direction D2. In summary, the center of the red luminescent region R, which is adjacent to the centers of the second luminescent region PX2, the third luminescent region PX3, and the sixth luminescent region PX6 along the second direction D2, may be located on an axis extending along the second direction D2.

[0083] In one embodiment, the center of the third light-emitting region PX3 can deviate from a predetermined range from an axis extending along a first direction D1 passing through the center of the first light-emitting region PX1. Specifically, the size of the predetermined range can be approximately 1 / 4 of the length of the first light-emitting region PX1 along the second direction D2. That is, the center of the third light-emitting region PX3 can be separated from the center of the first light-emitting region PX1 along the second direction D2 by a distance of approximately 1 / 4 of the length of the first light-emitting region PX1 along the second direction D2. Furthermore, the center of the third light-emitting region PX3 can be separated from the center of the first light-emitting region PX1 along a fourth direction D4 opposite to the second direction D2 by a distance of approximately 1 / 4 of the length of the first light-emitting region PX1 along the second direction D2. The same principle can also be applied to the third light-emitting region PX3 and the second light-emitting region PX2.

[0084] The first spacing distance h1 between the first emitting region PX1 and the third emitting region PX3, and the second spacing distance h2 between the second emitting region PX2 and the third emitting region PX3, can be substantially the same. The spacing distance can refer to the distance between the centers of each emitting region. The first emitting region PX1 and the second emitting region PX2 can be adjacent to the boundary of the first display region DA1, and the third emitting region PX3 can be adjacent to the boundary of the second display region DA2. The spacing distances along the first direction D1 and along the second direction D2 of other emitting regions adjacent to the boundaries of the first display region DA1 and the second display region DA2 and emitting the first color can also be substantially the same. Therefore, the spacing between the first display region DA1 and the second display region DA2 can be generally constant.

[0085] The third luminous region PX3 can be a chamfered rectangle. That is, the third luminous region PX3 can be an octagon. When the third luminous region PX3 is octagonal, the interval between the first luminous region PX1 and the third luminous region PX3, and the interval between the second luminous region PX2 and the third luminous region PX3, can be kept longer. Specifically, the interval between the first luminous region PX1 and the third luminous region PX3 can refer to the distance from the first corner of the first luminous region PX1 to the first side of the third luminous region PX3. The first corner can be a corner of the first luminous region PX1 adjacent to the third luminous region PX3. The first side can be a side of the third luminous region PX3 adjacent to the first luminous region PX1. Therefore, color mixing between the third luminous region PX3 and other luminous regions adjacent to the third luminous region PX3 can be prevented.

[0086] The first display area DA1 may include a fourth light-emitting area PX4 that emits the same first color as the second light-emitting area PX2 and is separated from it along the first direction D1. The first separation distance h1 between the first light-emitting area PX1 and the third light-emitting area PX3 may be substantially the same as the third separation distance h3 between the second light-emitting area PX2 and the fourth light-emitting area PX4. Therefore, the separation distances along the first direction D1 and the second direction D2 between the red light-emitting areas R included in the first display area DA1, the separation distances along the first direction D1 and the second direction D2 between the red light-emitting areas included in the second display area DA2, and the separation distances along the first direction D1 and the second direction D2 between the red light-emitting areas R adjacent to the boundary of the first display area DA1 and the second display area DA2 may be substantially the same.

[0087] Therefore, the interval between the first display area DA1 and the second display area DA2 can be kept constant. The interval between the first display area DA1 and the second display area DA2 can refer to the distance between the light-emitting area in the first display area DA1 that is closest to the second display area DA2 and the light-emitting area in the second display area DA2 that is closest to the first display area DA1.

[0088] For example, the first display area DA1 may include a seventh light-emitting area PX7 that is closest to the second display area DA2. Furthermore, the second display area DA2 may include an eighth light-emitting area PX8 that is closest to the first display area DA1. The distance h5 between the seventh light-emitting area PX7 and the eighth light-emitting area PX8 may refer to the interval between the first display area DA1 and the second display area DA2.

[0089] Therefore, in the display device 10, the interval between the first display area DA1 and the second display area DA2 can be kept small. Thus, the boundary between the first display area DA1 and the second display area DA2 can be ignored.

[0090] The eighth light-emitting region PX8 can emit a second color different from the first color. The second color can be green. The size of the eighth light-emitting region PX8 can be smaller than the size of the third light-emitting region PX3. Because the size of the eighth light-emitting region PX8, which is adjacent to the first display region DA1, is smaller than the size of the third light-emitting region PX3, color mixing can be prevented during the manufacture of the display device 10.

[0091] In one embodiment, the first display area DA1 may have a higher density than the second display area DA2. The first display area DA1 can display images. The second display area DA2 can perform other functions besides displaying images. Furthermore, the transmittance of the second display area DA2 may be higher than that of the first display area DA1. Therefore, the density of the light-emitting area PX of the second display area DA2 may be lower than that of the light-emitting area PX of the first display area DA1. Thus, the density of the light-emitting area PX of the first display area DA1 for displaying images increases, thereby increasing the resolution of the first display area DA1. The density of the light-emitting area PX of the second display area DA2 decreases, thereby increasing the transmittance of the second display area DA2.

[0092] The size of the light-emitting area included in the first display area DA1 can be smaller than the size of the light-emitting area included in the second display area DA2. Therefore, the first display area DA1 can include a larger light-emitting area within the same area compared to the second display area DA2. Consequently, the resolution of the first display area DA1 can be higher than the resolution of the second display area DA2. Furthermore, the width of the first display area DA1 can be greater than the width of the second display area DA2, resulting in the entire display device 10 having a high resolution.

[0093] As described above, the first display area DA1 may include a fourth light-emitting area PX4, which is separated from the second light-emitting area PX2 by a third separation distance h3 along the first direction D1. The second display area DA2 may also include a fifth light-emitting area PX5, which is separated from the third light-emitting area PX3 by a fourth separation distance h4 along the third direction D3. The third separation distance h3 may be smaller than the fourth separation distance h4. The distance between the light-emitting areas included in the first display area DA1 may be smaller than the distance between the light-emitting areas included in the second display area DA2. That is, the density of the first display area DA1 may be higher than the density of the second display area DA2.

[0094] By maintaining a narrow spacing between the first display area DA1 and the second display area DA2, which have different resolutions, the boundary between the first display area DA1 and the second display area DA2 can be made undetectable. Furthermore, color mixing can be prevented by constantly maintaining the spacing between the first display area DA1 and the second display area DA2.

[0095] Figure 4 This is a plan view illustrating a display device according to an embodiment of the present invention. Figure 5 It is magnification Figure 4 Plan view of area B. Figure 6 It is magnification Figure 5 Plan view of area C.

[0096] In reference Figures 4 to 6 In the configuration of the display device 11 described herein, for reference... Figures 1 to 3 The configuration of the display device 10 described herein has been described in the same manner, so it can be omitted below.

[0097] Reference Figures 4 to 6 The display device 11 may include a display panel 100, a flexible circuit board 20 connected to the display panel 100, and a driving device including a driving chip 30, etc.

[0098] The display panel 100 may include a substrate SUB, a barrier layer BRR, a buffer layer BFR, a transistor 200, an interlayer insulating layer 240, an insulating film 400, a pixel definition film 600, and a light-emitting diode 500.

[0099] The display panel 100 may include a first display area DA1 and a second display area DA2. The second display area DA2 may be located above the first display area DA1. The second display area DA2 may be located on the left or right side of the upper end of the display area DA, or it may be arranged separately on the left and right sides of the upper end of the display area DA, rather than being located in the center. The first display area DA1 may be arranged around the second display area DA2.

[0100] The second display area DA2 can be quadrilateral in shape. Specifically, the second display area DA2 may include first to fourth sides DA2a, DA2b, DA2c, and DA2d. One or more of the first to fourth sides DA2a, DA2b, DA2c, and DA2d of the second display area DA2 can be adjacent to the first display area DA1. Specifically, the first to third sides DA2a, DA2b, and DA2c of the second display area DA2 can be adjacent to the first display area DA1. However, the embodiments of the present invention are not limited to this. In another embodiment, only the second side DA2b of the second display area DA2 can be adjacent to the first display area DA1. Furthermore, in another embodiment, all of the first to fourth sides DA2a, DA2b, DA2c, and DA2d of the second display area DA2 can be adjacent to the first display area DA1. In yet another embodiment, all of the first to fourth sides DA2a, DA2b, DA2c, and DA2d of the second display area DA2 may not be adjacent to the first display area DA1.

[0101] The first display area DA1 and the second display area DA2 may include multiple light-emitting areas PX. For example, the first display area DA1 may include a first light-emitting area PX1 and a second light-emitting area PX2. The second display area DA2 may include a third light-emitting area PX3. The first light-emitting area PX1, the second light-emitting area PX2, and the third light-emitting area PX3 may emit a first color. The first color may be green. The third light-emitting area PX3, which is a green light-emitting area, may be one of the light-emitting areas in the second display area DA2 that is closest to the first display area DA1. Furthermore, the third light-emitting area PX3 may be adjacent to the first display area DA1 along the third direction D3 and the fourth direction D4. Therefore, when the first display area DA1 and the second display area DA2 are arranged with the third light-emitting area PX3 as a reference, it is effective in maintaining the spacing between the first display area DA1 and the second display area DA2. However, in another embodiment, the first color may be blue or red.

[0102] The size of each light-emitting region PX included in the first display area DA1 can be smaller than the size of each light-emitting region PX included in the second display area DA2. Therefore, the size of the third light-emitting region PX3 can be larger than the sizes of the first light-emitting region PX1 and the second light-emitting region PX2. The shapes of the first light-emitting region PX1 and the second light-emitting region PX2 can be rhomboid. The shape of the third light-emitting region PX3 can be quadrilateral.

[0103] The first luminescent region PX1 and the third luminescent region PX3 may be adjacent to each other along a first direction D1. The centers of the first luminescent region PX1 and the third luminescent region PX3 may be located on an axis extending along the first direction D1. The first display area DA1 may also include a fourth luminescent region PX4 separated from the first luminescent region PX1 along a third direction D3 opposite to the first direction D1. Similarly, the centers of the first luminescent region PX1 and the fourth luminescent region PX4 may be located on an axis extending along the first direction D1. In summary, the centers of each adjacent green luminescent region G of the first luminescent region PX1, the third luminescent region PX3, and the fourth luminescent region PX4 along the first direction D1 and the third third direction D3 may be located on an axis extending along the first direction D1.

[0104] The second luminescent region PX2 and the third luminescent region PX3 may be adjacent to each other along the second direction D2. The centers of the second luminescent region PX2 and the third luminescent region PX3 may be located on an axis extending along the second direction D2. The second display area DA2 may also include a fifth luminescent region PX5 separated from the third luminescent region PX3 along the second direction D2. Similarly, the centers of the third luminescent region PX3 and the fifth luminescent region PX5 may be located on an axis extending along the second direction D2. Therefore, the centers of the green luminescent regions G adjacent to each of the second luminescent regions PX2, the third luminescent region PX3, and the fifth luminescent region PX5 along the second direction D2 may be located on an axis extending along the second direction D2.

[0105] The first display area DA1 may further include a sixth light-emitting area PX6 adjacent to the fifth light-emitting area PX5 along a third direction D3, and a seventh light-emitting area PX7 adjacent to the sixth light-emitting area PX6 along a third direction D3. The sixth light-emitting area PX6 may emit a second color different from the first color. The seventh light-emitting area PX7 may emit a third color different from the second color. In one embodiment, the second color may be red, and the third color may be blue. The centers of the fifth light-emitting area PX5, the sixth light-emitting area PX6, and the seventh light-emitting area PX7 may be located on an axis extending along the first direction D1.

[0106] The first separation distance d1 between the first light-emitting area PX1 and the third light-emitting area PX3 and the second separation distance d2 between the second light-emitting area PX2 and the third light-emitting area PX3 can be substantially the same. Therefore, the interval between the first display area DA1 and the second display area DA2 can be generally constant.

[0107] Therefore, the interval between the first display area DA1 and the second display area DA2 can be maintained at a relatively narrow width. Consequently, the boundary between the first display area DA1 and the second display area DA2 can be ignored. Furthermore, since the distance between the centers of the light-emitting areas included in each of the first display area DA1 and the second display area DA2 is constant, color mixing will not occur between light-emitting areas emitting different colors.

[0108] In one embodiment, the first display area DA1 may have a higher density than the second display area DA2. The size of the light-emitting area included in the first display area DA1 may be smaller than the size of the light-emitting area included in the second display area DA2. Therefore, the first display area DA1 may include more light-emitting areas within the same area compared to the second display area DA2. Consequently, the resolution of the first display area DA1 may be higher than the resolution of the second display area DA2. Furthermore, the width of the first display area DA1 may be greater than the width of the second display area DA2, thereby enabling the entire display device 11 to have a high resolution.

[0109] As described above, the first display area DA1 may include a fourth light-emitting area PX4 that is separated from the first light-emitting area PX1 by a third separation distance d3 along the third direction D3. As described above, the second display area DA2 may include a fifth light-emitting area PX5 that is separated from the third light-emitting area PX3 by a fourth separation distance d4 along the second direction D2. The third separation distance d3 may be smaller than the fourth separation distance d4. The distance between the light-emitting areas included in the first display area DA1 may be smaller than the distance between the light-emitting areas included in the second display area DA2. That is, the density of the first display area DA1 may be higher than the density of the second display area DA2.

[0110] By maintaining a narrow gap between the first display area DA1 and the second display area DA2, which have different resolutions, the boundary between the first display area DA1 and the second display area DA2 can be made undetectable. Furthermore, color mixing can be prevented by constantly maintaining the gap between the first display area DA1 and the second display area DA2.
