Display panel and pixel array thereof

A pixel array, comprising:

• a plurality of pixel groups, each of the pixel groups at least comprising:
• a plurality of brightness sub-pixel regions, at least comprising five of the brightness sub-pixel regions, and each of the brightness sub-pixel regions having a first side, a second side, a third side, and a fourth side;
• a plurality of first sub-pixel regions, at least comprising a first group and a second group, each of the first sub-pixel regions at least having a long direction and a short direction, wherein the first group is disposed at the first side of the first brightness sub-pixel region, the second group is disposed at the third side of the first brightness sub-pixel region, an extension line of the long direction of the first group interlaces a vertical baseline at a first angle θ1, and an extension line of the long direction of the second group interlaces the vertical baseline at a second angle θ2, wherein the vertical baseline is perpendicular to a horizontal baseline;
• and
• a plurality of second sub-pixel regions, at least comprising a third group and a fourth group, each of the second sub-pixel regions at least having a long direction and a short direction, wherein the third group is disposed at the second side of the first brightness sub-pixel region, the fourth group is disposed at the fourth side of the first brightness sub-pixel region, an extension line of the long direction of the third group interlaces the vertical baseline at a third angle θ3, and an extension line of the long direction of the fourth group interlaces the vertical baseline at a fourth angle θ4, wherein 0°<θ1<90°, 0°<θ2<90°, 0°<θ3<90°, and 0°<θ4<90°.
