Abstract

A pixel array includes a plurality of pixel groups, each of which includes a plurality of brightness sub-pixel regions, a plurality of first sub-pixel regions, and a plurality of second sub-pixel regions. Each brightness sub-pixel regions has a first side, a second side, a third side, and a fourth side. The first sub-pixel regions include a first group and a second group, and the second sub-pixel regions include a third group and a fourth group. The first, the second, the third, and the fourth groups are respectively disposed at the first, the third, the second, and the fourth sides of the first brightness sub-pixel region. Extension lines of long directions of the first, the second, the third, and the fourth groups respectively interlace a vertical baseline at a first angle θ1, a second angle θ2, a third angle θ3, and a fourth angle θ4. 0°<θ1<90°, 0°<θ2<90°, 0°<θ3<90°, and 0°<θ4<90°.
