A pixel structure (100) and an active switch array substrate (200). The pixel structure (100) comprises: a first scan line (111); a second scan line (112), which is adjacent to the first scan line (111); a first data line (121);, a second data line (122), which is adjacent to the first data line (121); and a pixel electrode (130). The first scan line (111) and the second scan line (112) are arranged to intersect with the first data line (121) and the second data line (122) to jointly enclose a pixel unit region. The pixel electrode (130) is located in the pixel unit region and is electrically connected to the first scan line (111) and the first data line (121), at least one slit (131) extending from the first scan line (111) to the second scan line (112) is arranged on the pixel electrode (130), and the length direction of the slit (131) is inclined with respect to the length direction of the first scan line (111).
