A pixel structure includes a substrate, a scan line, a first data line, a second data line, a first active device, a second active device, a first pixel electrode, and a second pixel electrode. The substrate has a first unit area and a second unit area. The first pixel electrode is disposed in the first unit area and includes a first main portion and first branch portions extending from the first main portion to an edge of the first unit area. The second pixel electrode is disposed in the second unit area and includes a second main portion and second branch portions extending from the second main portion to an edge of the second unit area, wherein at least a part of the first branch portions and at least a part of the second branch portions are asymmetrically arranged at two sides of the second data line.
