Jeongyehyeong lateral liquid crystal display device and the manufacturing method

摘要

PURPOSE: An in-plane switching type LCD(Liquid Crystal Display) and a manufacturing method thereof are provided to prevent reduction of aperture ratio due to enlargement of line width of a black matrix in consideration with misalignment of two substrate of the LCD by forming an insulating layer between a wiring and an electrode thick so as to make the wiring overlap with electrode at a predetermined width. CONSTITUTION: A gate wiring, a data wiring(130), a common wiring(116), and a TFT(Thin Film Transistor)(T) consisting of a gate, a source and a drain electrodes are respectively formed on the first substrate(110). The gate wiring and the data wiring cross each other, thereby designating a pixel region. The first insulating layer(132) is formed to cover the TFT, the gate wiring and the data wiring, a portion of the common wiring, wherein the first insulating layer has contact holes for exposing the drain electrode and the common wiring. The first insulating layer(132) is formed of materials having high resistance characteristics. The second insulating layer(142) is formed to cover the pixel region, wherein the second insulating layer is formed of materials having high resistance characteristics. A plurality of pixel electrodes(144) and a plurality of common electrodes(146) are formed on the second insulating layer to electrically connect with the drain electrode and the common wiring.
