Method for producing array board of liquid crystal display device

Abstract

A manufacturing method of a liquid crystal display apparatus comprises that a grid line, a grid and a grid insulating layer are formed at a base plate in first mask working procedure; an active layer, an ohm contact layer, a source electrode, a drain electrode and a data line are formed at the grid insulating layer in second mask working procedure, the data line and the grid line are intersected to limit a pixel area, a first passivation layer is formed at the basically whole surface of the base plate which comprises the source electrode and the drain electrode; a black matrix is formed at the first passivation layer of the active layer in third mask working procedure; a color filter sheet layer is formed at the first passivation layer inside the pixel area in fourth mask working procedure, and a second passivation layer is formed at the surface of the base plate which comprises the black matrix and the color filter sheet layer; a photoresist design is formed in fifth mask working procedure, the photoresist design and the second passivation layer are composed as a picture to expose partial drain electrode, a transparent conductive layer and a pixel electrode are formed at the basically whole surface of the base plate which comprises partially exposed drain electrode, and the pixel electrode is contacted with the exposed partial drain electrode.

Description

[0001] This application claims priority to Korean Patent Application No. 2004-0050171 filed in Korea on June 30, 2004 and Korean Patent Application No. 2005-0010589 filed in Korea on February 4, 2005, which It is incorporated herein by reference. technical field [0002] The invention relates to a liquid crystal display device, more particularly to a method for manufacturing an array substrate of a liquid crystal display device having a color filter layer on a thin film transistor. Background technique [0003] Liquid crystal display (LCD) devices are driven on the basis of the optical anisotropy and polarization properties of liquid crystal materials. An LCD device generally includes two substrates spaced apart from and facing each other, and a layer of liquid crystal material sandwiched between the two substrates. Each substrate includes electrodes facing each other such that a voltage applied to each electrode generates an electric field between the electrodes perpendicu...
