Abstract: A liquid crystal display includes a first pixel, a second pixel, and a third pixel each displaying a different color. A first data line is positioned between the first pixel and the second pixel, and a second data line is positioned between the second pixel and the third pixel. A first pixel electrode, a second pixel electrode, and a third pixel electrode are respectively positioned in the first, second, and third pixels. An interval between the first pixel electrode and the first data line is larger than an interval between the second pixel electrode and the first data line. An interval between the second pixel electrode and the second data line is smaller than an interval between the third pixel electrode and the second data line.
