a substrate; and

at least one pixel unit comprising:

at least one pixel group disposed on the substrate, each of the at least one pixel group comprising six sub-pixels arranged at intervals in a first direction, and each of the six sub-pixels comprising at least one pixel electrode; and

at least three data line groups disposed on the substrate, the at least three data line groups comprising three data line groups, each of the three data line groups corresponding to the at least one pixel electrode of one of the six sub-pixels, and each of the three data line groups being located on one side of the at least one pixel electrode which is adjacent to the substrate;

wherein each of the three data line groups comprises two data lines arranged at intervals in the first direction, and the at least one pixel electrode of each of the six sub-pixels is electrically connected to a respective one of the two data lines of a corresponding one of the three data line groups;

wherein the six sub-pixels comprise two first color sub-pixels, two second color sub-pixels, and two third color sub-pixels: one of the three data line groups and one of the two first color sub-pixels are arranged correspondingly, other two of the three data line groups and the two second color sub-pixels are arranged correspondingly respectively, and the two data lines of each of the three data line groups are each electrically connected to the at least one pixel electrode of a corresponding one of two, which are of a same color, of the six sub-pixels.
