According to the mode, the distance between the two adjacent peripheral sub-pixels with the same color is smaller than the distance between the two adjacent peripheral sub-pixels with different colors, so that the two adjacent peripheral sub-pixels with the same color can be close enough, the same opening in the mask plate can be shared for vapor deposition of the two adjacent peripheral sub-pixels with the same color, and the pixel definition layer is arranged between the two adjacent sub-pixels, even if a single opening is adopted, the two adjacent peripheral sub-pixels with the same color but mutually independent can be vapor deposited, so that the number of openings required to be arranged in the same area in the corresponding mask plate is reduced, the area of the area between the adjacent openings due to the minimum distance limitation in the mask plate is reduced, and the opening ratio of the display panel manufactured based on the corresponding mask plate is improved.
In an embodiment, as shown in fig. 1 to 3, the plurality of peripheral sub-pixels in each pixel unit 10 includes two second sub-pixels 12 and two third sub-pixels 13, the first sub-pixel 11 is located between the two second sub-pixels 12, the first sub-pixel 11 is located between the two third sub-pixels 13, and the colors of the second sub-pixels 12 and the third sub-pixels 13 are different.
Specifically, the colors of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are different from each other.
As shown in fig. 1, all the subpixels in a single pixel unit 10 may be located within a cross-shaped area a as shown in fig. 1, a first subpixel 11 is located at the center of the cross-shaped area a, one of two second subpixels 12 is located at the left area within the cross-shaped area a, the other of the two second subpixels 12 is located at the right area within the cross-shaped area a, one of two third subpixels 13 is located at the upper area within the cross-shaped area a, and the other of the two third subpixels 13 is located at the lower area within the cross-shaped area a.

The second sub-pixel 12 located in the right region has a smaller distance from the boundary of the spider region a on its upper side than the distance from the boundary of the spider region a on its lower side.
The distance between the third sub-pixel 13 located in the upper region and the boundary of the spider region a on the left side thereof is smaller than the distance between the boundary of the spider region a on the right side thereof.

All the first sub-pixels 11 are arranged in an array.
Specifically, as shown in fig. 3, all the first sub-pixels 11 may be arranged in an array along the third direction D3 and the fourth direction D4 perpendicular to each other, so that the pixel units 10 may be arranged in an array along the third direction D3 and the fourth direction D4 as well.
There are two types of adjacent pixel units 10 among the plurality of pixel units 10, and each adjacent pixel unit group includes a first pixel unit and a second pixel unit, respectively.

in the second type of adjacent pixel unit group, a third sub-pixel 13 in the first pixel unit is disposed adjacent to a second sub-pixel 12 and a third sub-pixel 13 in the second pixel unit, respectively.
Specifically, as shown in fig. 2, the first pixel group B may be the above-mentioned first-type adjacent pixel unit
The two second sub-pixels 12 of the same color and adjacent to each other in the tuple, and the second pixel group C may be the two third sub-pixels 13 of the same color and adjacent to each other in the second adjacent pixel unit group of class 0.
In the two pixel units 10 corresponding to the first pixel group B, a second sub-pixel 12 in the upper right pixel unit 10 is adjacent to a second sub-pixel 12 and a third sub-pixel 13 in the lower left pixel unit 10, respectively, and two corresponding to the second pixel group C
Among the pixel units 10, a third sub-pixel 13 in the pixel unit 10 located at the upper left is adjacent to a second sub-pixel 12 and a third sub-pixel 13 in the pixel unit 10 located at the lower right, respectively, 5.
In the pixel arrangement constructed based on the above manner, the pixel units 10 are repeatedly arranged as the repeating units, and there are necessarily two adjacent second sub-pixels 12 or two adjacent third sub-pixels 13 between two adjacent pixel units 10, and since each two adjacent 0 sub-pixels are provided with the corresponding pixel definition layer, there are no gaps between the two adjacent second sub-pixels 12
Or two adjacent third sub-pixels 13 can be evaporated by adopting the same opening on the mask plate, and two corresponding adjacent but mutually independent second sub-pixels 12 or third sub-pixels 13 are generated by virtue of the separation of the pixel definition layers, thereby reducing the number of openings on the mask plate
The effect of the amount is further reduced, the area of the area 5 existing between adjacent openings in the mask plate due to the minimum distance limitation is further reduced, and the opening ratio of the display panel manufactured based on the corresponding mask plate is improved.
In addition, due to the improvement of the aperture ratio, the pixel density of the display panel can be correspondingly improved.
The same opening of the shared mask plate is used for evaporating the two sub-pixels, so that a bridging mechanism which is originally required to be established in the opening and used for dividing the two sub-pixels can be omitted, the manufacturing difficulty of the mask plate is reduced, and the manufacturing cost of the mask plate is further reduced.
It should be noted that, the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 may be in one-to-one correspondence with the blue sub-pixel, the green sub-pixel, and the red sub-pixel, or may be a combination of sub-pixels of other colors, which may be specifically determined according to actual needs, and are not limited herein.
Alternatively, two adjacent second sub-pixels 12 are disposed in order in the first direction.
Two adjacent third sub-pixels 13 are sequentially arranged in the second direction.
Wherein the first direction is perpendicular to the second direction.
Specifically, as shown in fig. 2 and 3, among the two pixel units 10 corresponding to the first pixel group B, a second sub-pixel 12 in the pixel unit 10 located at the upper right and a second sub-pixel 12 in the pixel unit 10 located at the lower left are sequentially arranged in the first direction D1.

Further, the third direction corresponding to the array arrangement is intersected with the first direction and the second direction respectively.
Specifically, as shown in fig. 3, a third direction D3 corresponding to the first sub-pixel 11 in the array arrangement crosses the first direction D1 and the second direction D2, the third direction D3 does not overlap the first direction D1 and the second direction D2, and as the third direction D3 is perpendicular to the fourth direction D4, a fourth direction D4 corresponding to the first sub-pixel 11 in the array arrangement crosses the first direction D1 and the second direction D2, and the fourth direction D4 does not overlap the first direction D1 and the second direction D2.
Based on the above mode, two adjacent sub-pixels can be sequentially arranged in the oblique direction different from the row-column direction of the array arrangement, so that the two sub-pixels of the same type are adjacent, but the two sub-pixels are sequentially arranged in the oblique direction relative to the array arrangement, so that the whole display panel has better pixel density perceived by a user in each direction of the horizontal direction, the vertical direction, the oblique direction and the like, and the display effect of the display panel in each direction is improved.

Optionally, the area of the first sub-pixel 11 is larger than the area of the second sub-pixel 12 and/or the area of the first sub-pixel 11 is larger than the area of the third sub-pixel 13.

Further, the difference between the area of the second sub-pixel 12 and the area of the third sub-pixel 13 is not greater than a preset area difference threshold.
Further, the difference between the area of the second sub-pixel 12 and the area of the third sub-pixel 13 is referred to as a target difference, the ratio between the target difference and the area of the second sub-pixel 12 is referred to as a first ratio, the ratio between the target difference and the area of the third sub-pixel 13 is referred to as a second ratio, and neither the first ratio nor the second ratio is greater than a preset ratio threshold.
Based on the above manner, the area difference between the second sub-pixel 12 and the third sub-pixel 13 can be prevented from being excessively large, thereby improving the display effect of the display panel.
Alternatively, the shape of the second sub-pixel 12 is the same as the shape of the third sub-pixel 13.
Specifically, the shapes of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 may be rectangular, in an example, the shape of the first sub-pixel 11 may be square, the shapes of the second sub-pixel 12 and the third sub-pixel 13 may be rectangular, and the shapes of the sub-pixels may also be other patterns and corresponding pattern combinations, which are not limited herein.
