A pixel structure disposed on a substrate having a horizontal direction and a vertical direction and driven by a scan line and a data line is provided. The pixel structure includes a pixel electrode and an active device. The pixel electrode has a first extension portion and a second extension portion connected to the first extension portion, wherein a first included angle of the first extension portion and the horizontal direction is θ degrees, a second included angle of the second extension portion and the horizontal direction is (360-θ) degrees, the data line is parallel to the first extension portion and the second extension portion, and a plurality of slits are perpendicular to the data line. The pixel electrode is electrically connected to the scan line and the data line via the active device.
