METHOD OF MANUFACTURING BLACK MATRIX USED IN LIQUID CRYSTAL DISPLAY DEVICE

摘要

PURPOSE: A method for manufacturing a black matrix is to prevent a numerical aperture from being reduced due to an error produced on adhering an upper and lower plate. CONSTITUTION: A thin film transistor(4) used as a switching element and a transparent electrode(5) used as a pixel electrode are formed on a transparent insulating substrate(1') through series of photographic etching process. After transparent pseudo-dyeing substance is applied on the entire surface of the thin film transistor and the transparent electrode through a spin coating or screen printing process, a pattern on which a black matrix is formed is formed on the thin film transistor except for the transparent electrode. After the pattern of the pseudo-dyeing substance is dyed with a black dye capable of excluding a light to form a black matrix, the substrate is processed with a fireproof process to complete the manufacture of the black matrix for a liquid crystal display.
