An (M)th stage of the first through (N)th stages includes a pull-up control part, a pull-up part, a carry holding part, a carry part, and a first pull-down part. The pull-up control part applies a second node signal of a second node to a first node in response to the second node signal. The pull-up part outputs a clock signal as an (M)th gate output signal in response to the first node signal. The carry holding part applies the (M)th gate output signal to the second node in response to the (M)th gate output signal. The carry part outputs the clock signal as an (M)th carry signal in response to the first node signal. The first pull-down part pulls down the (M)th gate output signal to a first off voltage.

Abstract: A liquid crystal display includes a first substrate with pixel electrodes, and a second substrate with a common electrode facing the first substrate. The common electrode has depression patterns corresponding to the pixel electrodes. The side wall of each depression pattern is at an angle of 30-120 degrees with respect to the first substrate. The depression patterns of the common electrode are formed through making depression patterns at color filters. In this structure, the liquid crystal display bears wide viewing angle and good picture quality.
