Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a color filter for preventing color mixing between adjoining pixels upon manufacturing a color filter by use of an ink-jet system. SOLUTION: The method includes the steps of: forming a light shielding layer in a predetermined pattern on a transparent substrate; discharging color materials of the respective colors onto openings of the light shielding layer to obtain a specified arrangement by an ink-jet method to form a color layer having a first film thickness; vaporizing the solvent in the color layer to reduce the film thickness of the color layer into a second film thickness smaller than the first film thickness; and heat treating the color layer. The ratio (T2/T1) of the second film thickness (T2) to the first film thickness (T1) is 0.6 to 0.95. COPYRIGHT: (C)2008,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method for a color filter for printing coloring ink with an ink jet, the manufacturing method for the color filter being characterized in that a partition wall part which does not deform owing to heat sagging of thermosetting resin of a black matrix and is in an ideal quadrangular or inversely tapered shape is provided to make a colored composition in each pixel flat and free of color unevenness. SOLUTION: Binder resin and a melamine derivative which crosslinks with the binder resin are used for the partition wall part, and cured at low temperature to obtain a partition wall part which is in an excellent shape free of heat sagging. Further, this partition wall part is not dissolved in coloring ink. Consequently, a colored composition in each pixel formed with an ink jet becomes flat and then a high-definition color filter can be obtained which is free of color unevenness and has excellent characteristics.
