A pixel structure disposed on a substrate including a scan line, a data line, an active element, a first electrode, and a second electrode is provided. The scan line and the data line are intersected to define a rectangular pixel area. The active element is electrically connected to the scan line and the data line. The first electrode has stripe patterns and connecting patterns located in the rectangular pixel area. Each connecting pattern is connected to the central parts or the parts near the central parts of two adjacent stripe patterns to demarcate or define two silts between the two adjacent stripe patterns. The extending direction of the slits is intersected to the rectangle length of the rectangular pixel area by an angle θ wherein 0°≦θ
