A liquid crystal display including a number of scan lines, a number of data lines, a pixel, a first switch circuit, and a second switch circuit is provided. The scan lines include an Nth scan line and an (N+1)th scan line, where N is a positive integer. The pixel includes a first sub-pixel and a second sub-pixel. The first switch circuit is coupled to both the Nth scan line and the (N+1)th scan line and is used for controlling the second sub-pixel. The second switch circuit is coupled to the Nth scan line and is used for controlling the first sub-pixel. The pixel is used for displaying a red, a green, a blue, or a white color.
