Abstract
A liquid crystal display includes: a first pixel and a second pixel for displaying different colors, the first pixel and the second pixel each including a first sub-pixel electrode receiving a first voltage; a second sub-pixel electrode receiving a second voltage; an insulating layer disposed between the first sub-pixel electrode and the second sub-pixel electrode; and a common electrode receiving a common voltage. A first portion of the first sub-pixel electrode and a second portion of the second sub-pixel electrode overlap each other, a difference between the first voltage and the common voltage is larger than a difference between the second voltage and the common voltage, and a ratio of the second voltage to the first voltage for the first pixel is different from a ratio of the second voltage to the first voltage for the second pixel.
