Fig. 8 is a schematic diagram of another pixel structure according to an embodiment of the invention. The pixel structure shown in fig. 8 is similar to the pixel structure shown in fig. 8, except that the first sub-pixel group 100 and the second sub-pixel group 200 in two pixel units 10 in the same pixel unit group 1 are arranged in different orders in the first direction X.
The pixel unit group 1 is a minimum repeating unit in the pixel structure, and a plurality of pixel unit groups 1 are repeatedly arranged to constitute the pixel structure.
It should be noted that, as shown in fig. 8, the different arrangement order means: the first sub-pixel group 100 and the second sub-pixel group 200 in one pixel unit 10 in the pixel unit group 1 are sequentially arranged in the first direction X, and the second sub-pixel group 200 and the first sub-pixel group 100 in another pixel unit 10 are sequentially arranged in the first direction X, that is, the structures of the first sub-pixel groups 100 in two pixel units 10 in the same pixel unit group 1 are completely the same, and the structures of the second sub-pixel groups 200 are also completely the same, and only the arrangement sequences of the two sub-pixel groups are different.

The misalignment width d refers to a distance between geometric centers of two pixel units 10 in the same pixel unit group 1 in the first direction X, and the width of the first sub-pixel group 100 refers to a length of the first sub-pixel group 100 in the first direction X.
It should be further noted that, due to the arrangement, the sub-pixels with different light emitting colors are arranged more closely, which is beneficial to the color mixing of the light with different colors emitted by each sub-pixel, and further improves the display effect of the display device.
Illustratively, as shown in fig. 3, 4, 9 and 10, the misalignment width d may be equal to half the width of the first sub-pixel group 100.
Experiments prove that when the misalignment width d is equal to half of the width of the first sub-pixel group 100, the tightness between the four sub-pixels with different colors in the pixel unit 10 is the highest, and the color mixing effect is the best, so that the display device has a better display effect.
