THIN FILM TRANSISTOR SUBSTRATE FOR REFLECTIVE LCD AND FABRICATING METHOD THEREOF

摘要

PURPOSE: A thin film transistor substrate for a reflective liquid crystal display device and a method for fabricating the same are provided to simplify the fabricating procedure by forming an embossing pattern on a photosensitive film for black matrix by using a black positive photosensitive film. CONSTITUTION: A method for fabricating a thin film transistor substrate for a reflective liquid crystal display device includes the steps of forming gate and data wires on an insulating substrate via a gate insulating film covering the gate wires or a semiconductor pattern formed on the gate insulating film on gate electrodes, forming a black matrix insulating film on the data wires and the semiconductor pattern by using a black photosensitive film, and forming a reflecting film connected to drain electrodes by using a conductive material with flexibility on the black matrix insulating film. The insulating film for the black matrix(80) is formed by the sub-steps of doping the photosensitive film, embossing the photosensitive film at positions corresponding to pixel areas by exposing and developing the photosensitive film by using mask, and forming first to third contact holes(101-103) for exposing the drain electrodes(62) and gate and data pads(24,64). The insulating film for the black matrix is flat at positions corresponding to the gate and data pads.
