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° 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.
