Title:
FABRICATION METHOD FOR COLOR FILM SUBSTRATE AND FABRICATION METHOD FOR LIQUID CRYSTAL PANEL
Document Type and Number:
WIPO Patent Application WO/2018/188114
Kind Code:
A1
Abstract:
A fabrication method for a color film substrate and fabrication method for a liquid crystal panel, comprising: providing a first substrate (100), the first substrate (100) comprising pixel unit areas (102) and shading areas (104) among the pixel unit areas (102); coating a photoresist material on the first substrate (100); exposing the pixel unit areas (102) to form single color resistor blocks, and partially exposing the shading areas (104) to form color resistor cushion blocks (302, 304); coating black photoresist materials (40) on the shading areas (104), and covering the color resistor cushion blocks (302, 304) using the black photoresist materials (40); and exposing the black photoresist materials (40) to make the black photoresist materials (40) in the shading areas (104) form black matrices (500) and the black photoresist materials (40) covering the color resistor cushion blocks (302, 304) form spacing columns (502, 504). The spacing columns (502, 504) are formed after the black photoresist materials (40) which use the color resistor cushion blocks (302, 304) as substrates are exposed, and the black matrices (500) are formed after the black photoresist materials (40) in other parts of the shading areas (104) are exposed. The described exposure process may be achieved by using a common photomask, and the cost of fabricating the color film substrate is low.
