Liquid crystal display device having structure of color filter on TFT and using in plane switching mode

摘要

A liquid crystal display device includes gate lines crossing data lines on a first substrate defining a pixel region; at least one common electrode formed in the pixel region; at least one pixel electrode in the pixel region, the at least one pixel electrode corresponding to the common electrode; a color filter layer formed within the pixel region excluding the gate line and the data line; a black matrix having at least three layers, an inner layer of the at least three layers being an electrode material.
