MANUFACTURING METHOD FOR LIQUID CRYSTAL COLOR FILTER, LIQUID CRYSTAL COLOR FILTER MANUFACTURED BY THE METHOD AND LIQUID CRYSTAL PANEL HAVING THE FILTER

摘要

PROBLEM TO BE SOLVED: To manufacture a highly reliable liquid crystal color filter capable of preventing mixing colors between adjacent pixels at the time of arraying coloring agents by ink jet by applying a coloring agent to the inside and outside of each pixel having a surface energy difference. SOLUTION: A photosensitive resin layer 3 is formed on the surface of a light shielding part (black matrix) 1 formed on a light transmitting substrate 2 as a pattern, an water repellent material is applied to the upper surface of the layer 3 to generate a surface energy difference between the inside and outside of each pixel and coloring agents are arrayed on the light transmitting part by ink jet using ink jet recorder so as not to generate color mixing. Pixels are colored by respective colors of R, G and B by the use of the ink jet recorder and then ink is baked. Both ink materials of a dyestuff group and a pigment group can be used as ink for coloring and either one of them is not specifically restricted. It is also available to previously form a resin layer (undercoat) on a coloring part to prevent uneveness of a color in a pixel.
