Abstract: A liquid crystal display including a plurality of scan lines, a plurality of data lines and a pixel array is provided. Each data line has a plurality of first vertical portions, a plurality of second vertical portions and a plurality of horizontal portions. The first vertical portions and the second vertical portions are perpendicular to the scan lines. The horizontal portions are parallel to the scan lines. The first vertical portion and the second vertical portion are alternately arranged. Each first vertical portion is connected to its neighboring second vertical portion by a horizontal portion. The pixel array includes a plurality of pixel units. The length of each horizontal portion is equal to the width of at least one pixel unit. The signals with opposite polarities are received by the pixel units on two sides of each horizontal portion.
