PRODUCTION OF COLOR FILTER SUBSTRATE

摘要

PURPOSE:To obtain the color filter substrate which is free from the fluctuation in liquid crystal thickness and unequal display by forming a resin layer of the same film thickness as the thickness of color filters on the substrate exclusive of the effective picture elements of the color filters, then forming a transparent flattening film on this substrate. CONSTITUTION:The resin layer 3 is formed of a color filter material over the entire region exclusive of the effective picture elements of the color filters simultaneously when the blue color filters 2c are printed. A transparent UV curing resin is printed and applied by a roll coater on this color filter substrate and thereafter the coated surface is pressed by a polished glass plate and is irradiated with UV rays and is thereby cured. The polished glass plate is thereafter parted to form the flattening film 4. The resin layer 3 of about the same thickness as the thickness of the color filters 2a to 2c is formed on the specific parts exclusive of the effective picture elements of the color filter substrate 1 and further, the flattening film 4 is formed on such substrate to flatten the ruggedness and waving of the color filters 2a to 2c. The color filter substrate having the high surface flatness is obtd. by the simple stage in this way and the color panel having the good optical performance without having unequal display is obtd.
