Examples of such a display device include a liquid crystal display device (LCD), an organic light emitting display device (OLED), and the like.

Among them, since the organic light emitting diode display is a self-luminous device, it has excellent viewing angle, contrast, and the like, and since it does not require a backlight unit, it can be lightweight and thin, and is advantageous in terms of power consumption. In addition, since it has advantages of fast response speed, luminous efficiency, luminance, and viewing angle compared to other display devices, it is receiving widespread attention. An organic light emitting diode applied to an organic light emitting display device is a next-generation light source having self-luminance characteristics, and has superior advantages over liquid crystal in terms of viewing angle, contrast, response speed, power consumption, and the like.

The organic light emitting diode display includes a white organic light emitting diode emitting white light and a white organic light emitting display including a colored color filter. In the white organic light emitting display device, since the organic light emitting device emits white light, a color filter for converting white light into chromatic light such as red light, green light, and blue light is used. Typically, a red color filter, a green color filter, and a blue color filter are used as the color filter.

However, in such a color filter, only light in the red, green, and blue wavelength bands corresponding to the color passed by each color filter is transmitted, so that light loss occurs in each color filter, and there is a problem in that energy efficiency is lowered.

Another problem to be solved by the present specification is to arrange sub-pixels composed of red, green, and blue sub-pixels of primary colors, cyan, magenta, and yellow sub-pixels of secondary colors, and white sub-pixels in one pixel to approximate natural colors. An object of the present invention is to provide an organic light emitting diode display that realizes color reproducibility and high resolution at the same time.

Another object of the present specification is to provide an organic light emitting diode display that reduces cracks in gate wirings during bending when implemented as a flexible display by alternately disposing concave and convex sub-pixels.

For example, when one pixel PX implements yellow light, the organic light emitting diode display 100 may not drive the other sub-pixels except for the yellow sub-pixel SPY. In addition, when the organic light emitting diode display 100 desires to drive yellow more vividly, the yellow sub-pixel SPY is driven and the red sub-pixel SPR and the green sub-pixel SPG are auxiliary and simultaneously driven. may be Conversely, the organic light emitting diode display 100 may drive the red sub-pixel SPR and the green sub-pixel SPG, and may additionally drive the yellow sub-pixel SPY.

4 is a CIE 1931 color coordinate system for describing an organic light emitting diode display according to an exemplary embodiment of the present specification. The CIE 1931 color coordinate system is a standard colorimetry system established in 1931 by the International Commission on Illumination (CIE), and expresses all the gamut of colors visible to the average human eye. The area near each vertex of the color gamut of the CIE 1931 color coordinate system represents the primary colors of red, green, and blue light, and the area near each side is realized when two of red, green, and blue lights are mixed. It represents light of secondary colors of cyan, magenta and yellow. And, the center of the color gamut represents white light realized when all colors of light are mixed. In addition, a range of colors that can be implemented within a color gamut varies according to a display device that implements light.

Referring to FIG. 4 , when the organic light emitting diode display according to the comparative example and the organic light emitting display 100 according to the exemplary embodiment of the present specification are driven, a color gamut perceived by a human is shown. In the example, in the case of the organic light emitting diode display 100 according to an embodiment of the present specification, a color gamut perceived by a human is shown in a color gamut of the CIE 1931 color coordinate system. The comparative example is an organic light emitting diode display according to the comparative example. When each pixel includes red, green, and blue sub-pixels and white sub-pixels that implement light of a primary color, in the color gamut of the CIE 1931 color coordinate system, a human The perceived color gamut is shown.

Referring to FIG. 4 , a region corresponding to a secondary color among the color gamut of the comparative example, that is, each side of the color gamut is disposed inside of each side of the color gamut of the embodiment. For example, since the organic light emitting diode display according to the comparative example has a narrower range than the organic light emitting diode display 100 according to the exemplary embodiment of the present specification, the secondary color may be insufficient.

For example, if each side of the secondary color, that is, the color gamut is compared, each side of the organic light emitting diode display according to the comparative example is more inside than each side of the organic light emitting display 100 according to the exemplary embodiment of the present specification. Because it is located in , the secondary color realization range is narrow. Therefore, when both the organic light emitting diode display according to the comparative example and the exemplary embodiment of the present specification implement a secondary color, the user can determine that the organic light emitting display device according to the comparative example is the organic light emitting display device according to the exemplary embodiment of the present specification ( 100), it can be recognized that the color is not as vivid.

The plurality of pixels PX of the organic light emitting diode display 100 according to the exemplary embodiment of the present specification includes a color filter 140 having a primary color and a secondary color corresponding to each sub-pixel SP. Accordingly, the secondary color light can be directly implemented by using only the secondary color color filters 144, 145, and 146 without mixing the primary color light that has passed through the primary color filters 141, 142, and 143. have. In addition, by using the light that has passed through the two primary color filters 141, 142, and 143 to the light that has passed through the secondary color filters 144, 145, and 146 as an auxiliary role, the color clarity can be improved. have. Accordingly, the organic light emitting diode display 100 according to the exemplary embodiment of the present specification may implement light of a secondary color having a strong intensity, thereby realizing light of a color closer to a natural color. In addition, the organic light emitting diode display 100 according to the exemplary embodiment of the present specification may implement a high-resolution pixel structure by increasing the number of sub-pixels SP disposed in one pixel PX. Accordingly, the organic light emitting diode display 100 can more delicately adjust color saturation, luminance, and the like, thereby realizing a realistic screen. In addition, the organic light emitting diode display according to the embodiment of the present specification may implement 6K to 8K resolution. 6K resolution can be said to be the image quality corresponding to the standard of 6400X1440 with the number of pixels, and it can be said that the 8K resolution is the video quality with the number of pixels corresponding to the standard of 7680X4320.

In addition, the white light emitted from the organic light emitting diode passes through the color filter and the luminance is lowered. A higher voltage may be applied to the organic light emitting diode in order to compensate for such a decrease in luminance. However, although the luminance is improved by increasing the driving voltage, there is a problem in that the lifespan of the organic light emitting diode is reduced due to the high driving voltage.

Accordingly, the plurality of pixels PX of the organic light emitting diode display 100 according to the exemplary embodiment of the present specification include white sub-pixels SPW1 and SPW2. Since the white light emitted from the organic light emitting diode 130 of the white sub-pixels SPW1 and SPW2 does not pass through the colored color filter 140 , a decrease in luminance due to passing through the color filter 140 can be reduced. . In addition, since the white sub-pixels SPW1 and SPW2 are used, the driving voltage may not be excessively increased in order to increase the intensity of white light emitted from the organic light emitting diode 130 . Accordingly, the organic light emitting diode display 100 according to the exemplary embodiment of the present specification may improve luminance by using the fourth sub-pixel SPW1 and the eighth sub-pixel SPW2 which are white sub-pixels.

5 is a schematic plan view illustrating a pixel of an organic light emitting diode display according to another exemplary embodiment of the present specification. The pixel PX of the organic light emitting diode display shown in FIG. 5 has a different area than the pixel PX of the organic light emitting diode display shown in FIG. 2 , and other components are substantially the same Therefore, redundant description is omitted.

Referring to FIG. 5 , the first sub-pixel SPR to the fourth sub-pixel SPW1 of the pixel PX has a larger area than the fifth sub-pixel SPC to the eighth sub-pixel SPW2 of the pixel PX. have Accordingly, the light realized when the first sub-pixel SPR to the fourth sub-pixel SPW1 is respectively driven is greater than the light realized when the fifth sub-pixel SPC to the eighth sub-pixel SPW2 are respectively driven. It can be clearly implemented with high luminance.

In the organic light emitting diode display according to another exemplary embodiment of the present specification, a first sub-pixel that is a sub-pixel that emits red, green, and blue lights to correspond to red, green, and blue lights, which are primary color lights having a relatively high implementation frequency, respectively. Areas of the (SPR) to the third sub-pixels SPB may be increased. Accordingly, high luminance light may be realized by driving only the first sub-pixel SPR to the third sub-pixel SPB to realize red, green, and blue colors.

And, in the organic light emitting diode display according to another exemplary embodiment of the present specification, for example, when one pixel PX implements white light, the first sub-pixel SPR to the third sub-pixel SPB are formed. High intensity white light can be realized by simultaneously driving them. In addition, the organic light emitting diode display may increase the luminance of white light by additionally driving the fourth sub-pixel SPW1 or the eighth sub-pixel SPW2 . In addition, if the luminance of white light to be realized by the organic light emitting diode display is low, white light having a desired luminance may be realized by simultaneously driving the fifth sub-pixel SPC to the seventh sub-pixel SPY.

Accordingly, in the organic light emitting diode display according to another exemplary embodiment of the present specification, the areas of the plurality of sub-pixels SP constituting each pixel PX are different. The sub-pixel SP having a relatively large area may implement light of a bright color having a higher luminance than the sub-pixel SP having a relatively small area. Accordingly, in the organic light emitting diode display according to another exemplary embodiment of the present specification, the area of the sub-pixel SP that implements light of a color that is frequently used is relatively large, so that light having a higher luminance can be realized. In addition, since it is not necessary to simultaneously drive a plurality of sub-pixels SP to realize light of a color that is frequently used, power consumption of the organic light emitting diode display can be reduced and lifespan can be improved.

6 is a schematic plan view illustrating a pixel of an organic light emitting diode display according to another exemplary embodiment of the present specification. The pixel PX of the organic light emitting diode display shown in FIG. 6 has a different area and number of white sub-pixels SPW compared to the pixel PX of the organic light emitting display device of FIG. 5 , and other components are substantially the same Therefore, redundant description is omitted.

Referring to FIG. 6 , the pixel PX includes a first sub-pixel SPR to a seventh sub-pixel SPY. Each of the first sub-pixel SPR, the second sub-pixel SPG, and the third sub-pixel SPB is a red sub-pixel, a green sub-pixel, and a blue sub-pixel, and the fifth sub-pixel SPC and the sixth sub-pixel Each of SPM and the seventh sub-pixel SPY is a cyan sub-pixel, a magenta sub-pixel, and a yellow sub-pixel. And, the fourth sub-pixel SPW is a white sub-pixel. For example, the pixel PX of the organic light emitting diode display according to another exemplary embodiment of the present specification includes a fourth sub-pixel SPW, which is a single white sub-pixel having the largest area compared to other sub-pixels. The fourth sub-pixel SPW is disposed over the entire first row and the second row. Accordingly, although the area of the pixels for emitting white light is the same, since the number of sub-pixels for emitting white light is reduced, the area of the circuit unit for driving the sub-pixels for emitting white light can be reduced, and accordingly An aperture ratio of the organic light emitting diode display may be improved, thereby improving luminance.

7 is a schematic plan view illustrating a pixel of an organic light emitting diode display according to another exemplary embodiment of the present specification.

In addition, each of the first sub-pixel SPR to the eighth sub-pixel SPW2 of the first pixel PX1 and the second pixel PX2 may be a sub-pixel SP having the same area and the same color. For example, the first sub-pixel SPR of the first pixel PX1 and the second pixel PX2 is a red sub-pixel, and the second sub-pixel S of the first pixel PX1 and the second pixel PX2 is SPG is a green sub-pixel, the third sub-pixel SPB of the first pixel PX1 and the second pixel PX2 is a blue sub-pixel, and the first pixel PX1 and the second pixel PX2 are second The fourth sub-pixel SPW1 is a first white sub-pixel, the fifth sub-pixel SPC of the first and second pixels PX1 and PX2 is a cyan sub-pixel, and the first and second pixels PX1 and PX2 are cyan. The sixth sub-pixel SPM of the pixel PX2 is a magenta sub-pixel, the seventh sub-pixel SPY of the first and second pixels PX1 and PX2 is a yellow sub-pixel, and the first pixel PX1 ) and the eighth sub-pixel SPW2 of the second pixel PX2 may be a second white sub-pixel.

In addition, the fifth sub-pixel SPC to the eighth sub-pixel SPW2 of the second pixel PX2 are disposed in the first row, and the first sub-pixel SPR to the fourth sub-pixel SPW1 are second placed in a row Accordingly, each of the sub-pixels SP of the first pixel PX1 and the second pixel PX2 is symmetrically disposed. However, the arrangement order of the sub-pixels SP illustrated in FIG. 7 is exemplary and is not limited thereto.

In the organic light emitting diode display according to another exemplary embodiment of the present specification, each of the sub-pixels SP of the first pixel PX1 and the second pixel PX2 is symmetrically disposed. For example, the first sub-pixel SPR to the fourth sub-pixel SPW1 of the first pixel PX1 are arranged in the first row, and the fifth sub-pixel SPC to the eighth sub-pixel SPW2 are It is disposed in a second row adjacent to the first row, and the fifth sub-pixel SPC to the eighth sub-pixel SPW2 of the second pixel PX2 is disposed in the first row, and the first sub-pixel SPR to The fourth sub-pixel SPW1 is disposed in the second row. Accordingly, since the sub-pixels SP displaying the same color are alternately arranged in the first row and the second row, a more natural color when displaying a single color compared to the case where the sub-pixels SP showing the same color are arranged only in the same row Marking may be possible, and may be advantageous in terms of character readability.

8 is a schematic plan view illustrating a pixel of an organic light emitting diode display according to another exemplary embodiment of the present specification. The organic light emitting diode display shown in FIG. 8 differs from the organic light emitting diode display of FIG. 7 only in the area of each sub-pixel SP, and other configurations are substantially the same, and thus a redundant description thereof will be omitted.

Referring to FIG. 8 , each of the first sub-pixel SPR to the fourth sub-pixel SPW1 of the first pixel PX1 and the second pixel PX2 has the same area, and the first pixel PX1 and the second pixel PX2 have the same area. Each of the fifth sub-pixels SPC to the eighth sub-pixels SPW2 of the second pixel PX2 has the same area. In addition, the area of the first sub-pixel SPR to the fourth sub-pixel SPW1 is larger than the area of the fifth sub-pixel SPC to the eighth sub-pixel SPW2 .

For example, the first sub-pixel SPR to the fourth sub-pixel SPW1 of the first pixel PX1 disposed in the first row and the first sub-pixel of the second pixel PX2 disposed in the second row Each of the (SPR) to fourth sub-pixels SPW1 has the same first area. In addition, the fifth sub-pixel SPC to the eighth sub-pixel SPW2 of the first pixel PX1 arranged in the second row and the fifth sub-pixel SPC of the second pixel PX2 arranged in the first row ) to the eighth sub-pixels SPW2 each have the same second area, and the second area is smaller than the first area. Accordingly, the area of the first row of the first pixel PX1 is larger than the area of the second row, and the area of the first row of the second pixel PX2 is smaller than the area of the second row.

Accordingly, the first sub-pixel SPR to the fourth sub-pixel SPW1 disposed in the first row of the first pixel PX1 and the first sub-pixel SPR disposed in the second row of the second pixel PX2 ) to the light realized when the fourth sub-pixel SPW1 is driven, the fifth sub-pixel SPC to the eighth sub-pixel SPW2 and the second pixel arranged in the second row of the first pixel PX1 When the fifth sub-pixels SPC to the eighth sub-pixels SPW2 disposed in the first row of PX2 are driven, luminance may be higher and more vivid than that of light that is realized.

For example, the first to third sub-pixels SPR that implement red, green, and blue primary colors of light in the first row of the first pixel PX1 and the second row of the second pixel PX2 . The pixel SPB and the first white sub-pixel SPW1 are arranged, and the light of secondary colors of cyan, magenta, and yellow is applied to the second row of the first pixel PX1 and the first row of the second pixel PX2 . A fifth sub-pixel SPC to a seventh sub-pixel SPY and a second white sub-pixel SPW2 to be implemented are disposed. In addition, the area of the first sub-pixel SPR to the third sub-pixel SPB of each of the first pixel PX1 and the second pixel PX2 that implements the light of the primary color is the second pixel that implements the light of the secondary color. The area of the fifth sub-pixel SPC to the seventh sub-pixel SPY of the first pixel PX1 and the second pixel PX2 is larger than that of the first pixel PX1 and the second pixel PX2 .

In the organic light emitting diode display according to another exemplary embodiment of the present specification, the area of each of the plurality of sub-pixels SP constituting each pixel may be different. For example, the pixel includes a first pixel PX1 and a second pixel PX2 , and the first sub-pixels SPR to the fourth sub-pixels SPR of the first pixel PX1 and the second pixel PX2 are SPW1 may have a larger area than the fifth sub-pixel SPC to the eighth sub-pixel SPW2 of the first pixel PX1 and the second pixel PX2 . As the area of the sub-pixel SP increases, a stronger light intensity may be realized. Accordingly, by increasing the area of the sub-pixel for realizing light of a color that is relatively frequently used, it is possible to realize light of a clear color. For example, when the frequency of use of the primary color is high, the area of the sub-pixel that implements the light of the primary color may be increased. Accordingly, since the area of the sub-pixel can be variably designed in consideration of the frequency of use of colors and the lifespan of the organic light emitting diode, the lifespan and power consumption of the organic light emitting diode display can be improved.

Accordingly, the first sub-pixel SPR to the eighth sub-pixel SPW2 of each of the first pixel PX1 and the second pixel PX2 are arranged in the same row.

And, in the first row, each of the first sub-pixel SPR to the fourth sub-pixel SPW1 of the first pixel PX1 is the first sub-pixel SPR to the fourth sub-pixel of the second pixel PX2 , respectively. (SPW1) has a larger area compared to each. And, in the second row, each of the fifth sub-pixels SPC to the eighth sub-pixels SPW2 of the first pixel PX1 is the fifth sub-pixel SPC to the eighth sub-pixels of the second pixel PX2 . (SPW2) has a small area compared to each.

For example, the first sub-pixel SPR to the fourth sub-pixel SPW1 of the first pixel PX1 and the fifth sub-pixel SPC to the eighth sub-pixel SPW2 of the second pixel PX2, respectively has the same first area. In addition, the fifth sub-pixel SPC to the eighth sub-pixel SPW2 of the first pixel PX1 and the first sub-pixel SPR to the fourth sub-pixel SPW1 of the second pixel PX2 are the same, respectively. It has a second area, wherein the first area is larger than the second area.

Accordingly, the first sub-pixel SPR to the fourth sub-pixel SPW1 of the first pixel PX1 and the fifth sub-pixel SPC to the eighth sub-pixel SPC of the second pixel PX2 having the first area The light realized when the SPW2 is driven is the fifth sub-pixel SPC to the eighth sub-pixel SPW2 of the first pixel PX1 having the second area, and the first sub-pixel of the second pixel PX2 . When the (SPR) to fourth sub-pixels SPW1 are driven, the light may have a stronger intensity than the realized light.

In the organic light emitting diode display according to another exemplary embodiment of the present specification, a plurality of sub-pixels constituting each pixel may be configured to have different areas. For example, the pixel includes a first pixel PX1 and a second pixel PX2 , and the first sub-pixel SPR to the fourth sub-pixel SPW1 and the second pixel PX1 of the first pixel PX1 . The fifth sub-pixel SPC to the eighth sub-pixel SPW2 of PX2 are the fifth sub-pixel SPC to the eighth sub-pixel SPW2 of the first pixel PX1 and the second sub-pixel SPW2 of the second pixel PX2 . It may have a larger area than the first to fourth sub-pixels SPW1. A sub-pixel having a relatively large area may implement light of a stronger intensity. For example, when the frequency of use of the primary color is high, the first pixel PX1 having a larger area of a sub-pixel realizing the light of the primary color is driven, and when the frequency of use of the secondary color is high, the light of the secondary color is high Power consumption may be reduced and color reproducibility may be improved by driving the second pixel PX2 having a larger sub-pixel area for realizing .

10 is a schematic plan view illustrating a pixel of an organic light emitting diode display according to another exemplary embodiment of the present specification. The pixel of the organic light emitting diode display illustrated in FIG. 10 has a different area of each sub-pixel compared to the pixel of the organic light emitting diode display illustrated in FIG. 8 , and other components are substantially the same, and thus a redundant description will be omitted.

The to fourth sub-pixels SPW1 are disposed in a second row adjacent to the first row. In addition, the fifth sub-pixel SPC to the eighth sub-pixel SPW2 of the first pixel PX1 are disposed in the second row, and the fifth sub-pixel SPC to the eighth sub-pixel SPC of the second pixel PX2 . The pixel SPW2 is disposed in the first row.

In addition, the first sub-pixels SPR to the fourth sub-pixels SPW1 of the first pixel PX1 and the fifth sub-pixels SPC to the eighth sub-pixels of the second pixel PX2 are arranged in the first row. (SPW2) each has the same area. The fifth sub-pixels SPC to the eighth sub-pixels SPW2 of the first pixel PX1 and the first sub-pixels SPR to the fourth sub-pixels SPW1 of the second pixel PX2 are arranged in the second row. ) each has the same area. In addition, the area of the sub-pixels SP arranged in the first row is larger than the area of the sub-pixels SP arranged in the second row.

For example, the first sub-pixels SPR to the fourth sub-pixels SPW1 of the first pixel PX1 and the fifth sub-pixels SPC to the eighth sub-pixels SPC of the second pixel PX2 are arranged in the first row. Each of the sub-pixels SPW2 has a first area, and the fifth sub-pixels SPC to the eighth sub-pixels SPW2 of the first pixel PX1 and the second pixel PX2 are arranged in the second row. Each of the first sub-pixel SPR to the fourth sub-pixel SPW1 has a second area smaller than the first area.

Accordingly, the first sub-pixels SPR to the fourth sub-pixels SPW1 of the first pixel PX1 and the fifth sub-pixels SPC to the eighth sub-pixels of the second pixel PX2 are arranged in the first row. The light realized when the SPW2 is driven is the fifth sub-pixel SPC to the eighth sub-pixel SPW2 of the first pixel PX1 arranged in the second row, and the first of the second pixel PX2 . When the sub-pixel SPR to the fourth sub-pixel SPW1 are driven, the light may have a sharper and stronger intensity than the realized light.

Specifically, the pixel includes a first pixel PX1 and a second pixel PX2 , and the first pixel PX1 has a larger area of the sub-pixel SP that implements the light of the primary color, and the second pixel In (PX2), the area of the sub-pixel SP that implements the light of the secondary color is larger. In addition, as the area of the sub-pixel SP increases, light having a stronger intensity may be realized. Accordingly, when the frequency of use of the primary color is high, the first pixel PX1 is preferentially driven, and when the frequency of use of the secondary color is high, the second pixel PX2 is preferentially driven to reproduce vivid colors. . Accordingly, in the organic light emitting display device according to another exemplary embodiment of the present specification, a first pixel PX1 having a large area of a sub-pixel SP implementing light of a primary color and a sub-pixel ( ) implementing light of a secondary color Since the second pixels PX2 having a large SP are alternately arranged to selectively use one of the first pixels PX1 and the second pixels PX2 according to the frequency of use of the primary colors and the secondary colors, Color reproducibility close to natural color may be realized, and lifespan and power consumption of the organic light emitting diode display may be improved.

11 is a schematic plan view illustrating a pixel of an organic light emitting diode display according to another exemplary embodiment of the present specification. The pixel PX of the organic light emitting diode display shown in FIG. 11 has a different shape than the pixel PX of the organic light emitting display device shown in FIG. 2 , and other components are substantially the same Therefore, redundant description is omitted.

Referring to FIG. 11 , in the pixel PX, the first sub-pixels SPR to the fourth sub-pixels SPW1 arranged in the first row and the fifth sub-pixels SPC to the eighth sub-pixels arranged in the second row are shown in FIG. The boundary of the pixel SPW2 has a zigzag shape.

For example, the upper and lower sides of the first sub-pixel SPR have a convex shape, and the upper and lower sides of the fourth sub-pixel SPW1 have a concave shape that is in contact with the convex side of the first sub-pixel SPR. The second sub-pixel SPG is disposed in the same column as the fifth sub-pixel SPC, and similarly, the second sub-pixel SPG and the fifth sub-pixel SPC also contact each other. Also, unlike the first sub-pixel SPR, the second sub-pixel SPG has a concave upper surface and lower sides, and the fifth sub-pixel SPC has a concave upper surface and a convex upper surface and lower side oppositely. As described above, some sides of the plurality of sides of each sub-pixel SP are configured as concave or convex sides, and the concave side and the convex side are disposed to contact each other. Accordingly, since a concave shape and a convex shape are alternately arranged on one side of each sub-pixel SP in contact with the boundary between the first row and the second row, the boundary between the first row and the second row has a zigzag shape, for example For example, it may have a wavy shape. In addition, the shape of the sub-pixel SP shown in FIG. 11 is exemplary and is not limited thereto.

A gate line, a data line, etc. may be disposed along the plurality of sub-pixels SP. For example, the gate wirings may be arranged in a row direction, and the data wirings may be arranged in a column direction. 11 , when the boundary of the plurality of sub-pixels SP is implemented in a wavy shape instead of a straight line, the gate wiring may be implemented in a zigzag shape.

In addition, both sides of the plurality of sub-pixels SP may have a convex shape or a concave shape. In this case, the data line may be implemented in a zigzag shape. In addition, all four sides of the plurality of sub-pixels SP may have a convex shape and a concave shape. In this case, both the gate line and the data line may be implemented in a zigzag shape.

In the organic light emitting diode display according to another exemplary embodiment of the present specification, various shapes of the plurality of pixels PX may be implemented. For example, each of the plurality of pixels PX includes a first sub-pixel SPR to an eighth sub-pixel SPW2 , and the first sub-pixel SPR to the fourth sub-pixel SPW1 is arranged in a first row and the fifth sub-pixel SPC to the eighth sub-pixel SPW2 are disposed in a second row adjacent to the first row. In addition, one side of each sub-pixel SP disposed at the row boundary has a concave shape or a convex shape, and the concave shape side and the convex shape side are alternately disposed so that the boundary of each row has a zigzag shape like a wave. can Accordingly, the shape of the gate line and the data line disposed along each sub-pixel SP may also be implemented in a zigzag shape. When the organic light emitting display device according to another exemplary embodiment of the present specification is implemented as a flexible display device, the organic light emitting display device is repeatedly bent, and wiring disposed on the organic light emitting display device may be cracked. Accordingly, in the organic light emitting diode display according to another exemplary embodiment of the present specification, the shape of the sides in contact with each other of the plurality of sub-pixels SP is formed in a convex or concave shape, and the gate wiring disposed in the plurality of sub-pixels SP; Since at least one of the data lines is formed in a concave or convex shape, it is possible to reduce cracks in the lines due to stress applied during bending of the organic light emitting diode display.

12 is a schematic plan view illustrating a pixel of an organic light emitting diode display according to another exemplary embodiment of the present specification. Referring to FIG. 12 , a pixel PX of an organic light emitting diode display according to another exemplary embodiment of the present specification includes a plurality of sub-pixels SP arranged in a row direction and a column direction, and the plurality of sub-pixels SP ), the gate line GL is disposed in the row direction, and the data line DL is disposed in the column direction.

For example, the first sub-pixel SPR to the fourth sub-pixel SPW1 are disposed in the first row, and the fifth sub-pixel SPC to the eighth sub-pixel SPW2 are disposed in the second row. The thin film transistors disposed in the plurality of sub-pixels SP disposed in the first row and the second row are connected to the same gate line GL. In addition, the second sub-pixel SPG and the fifth sub-pixel SPC, the third sub-pixel SPB and the sixth sub-pixel SPM, the fourth sub-pixel SPW1 and the seventh sub-pixel SPY are Each is connected to the same data line DL.

In a conventional organic light emitting diode display, a gate line is disposed in each row and a data line is disposed in each column of a plurality of sub-pixels disposed in a row direction and a column direction. However, in order to realize a high resolution, the number of sub-pixels increases, and accordingly, the number of gate lines and data lines also increases. Accordingly, the aperture ratio may be reduced due to the arrangement of the gate wiring and the data wiring. When the aperture ratio is reduced, since only a portion of light actually emitted from the white organic light emitting diode is realized as a screen, an organic light emitting diode display having a low aperture ratio requires a higher driving voltage than an organic light emitting diode display having a high aperture ratio, and thus white Lifespan of the organic light emitting diode may also be reduced.

Accordingly, the pixel PX of the organic light emitting diode display according to another exemplary embodiment of the present specification may improve the aperture ratio by sharing the gate line GL and the data line DL in adjacent rows and columns, respectively, Lifespan of the organic light emitting diode display may be improved.
