A pixel structure including a substrate, a scan line, a first data line, a second data line, a first pixel unit and a second pixel unit is provided. The first pixel unit includes a first active device and a first pixel electrode. The first active device is electrically connected to the scan line and the first data line. The first pixel electrode electrically connected to the first active device and has a plurality of first branches. The first branches outwardly extend from a center of the first pixel unit, and a projection of the first branches are separated from a projection of the adjacent first data line projecting onto the substrate, and the first pixel electrode is apart from the adjacent first data line with a distance. The second pixel unit located between the first data line and the second data line.
