METHOD FOR MANUFACTURING LCD

摘要

PURPOSE: A method for manufacturing an LCD(Liquid Crystal Display) is provided to reduce a crosstalk between a storage wiring and a data line and increase an aperture ratio, without increasing a surplus metal wiring area for forming a storage electrode. CONSTITUTION: A gate electrode(10), a storage electrode(15) and a pad electrode(20) are formed simultaneously on a glass substrate(5). A first, second and third insulation films(35) are sequentially deposited on an upper portion of the substrate(5) including the gate electrode(10), the storage electrode(15) and the pad electrode(20). An amorphous silicon layer(40) is deposited on an upper portion of the third insulation film(35). After depositing an ohmic layer, an active pattern is formed by a photolithography process. Thereafter the amorphous silicon layer(40) and the third insulation layer(35) are etched and then the second insulation layer(30) is etched. In the storage electrode, a via hole is formed to a storage electrode portion including the storage electrode(15) for increasing the storage capacity. Pixel electrodes(65a)(65b)(65c) are formed by using a transparent conductive film. At this time, the storage electrode(15) is positioned in parallel to a data line at the inside of a black matrix line formed at a color filter substrate.
