Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a color filter having smooth pixel shape and CF surface by using an inkjet method.
SOLUTION: The method of manufacturing the color filter includes at least the steps of: forming a light-shielding layer having a predetermined pattern, on a transparent substrate; discharging a colored ink to an opening of the light-shielding layer by using the inkjet method to achieve a predetermined arrangement, and thereafter evaporating a solvent to form a colored layer (drying step); and heat-curing the colored layer for formation (heating step). The film thickness distribution in the colored layer obtained through the drying step falls in the range of 80 to 110% of the film thickness of the light-shielding layer. Moreover, the pressure in a furnace during the heating step is 1,000 Pa or lower.

Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of an ink ejection printed matter by an ink ejection system which does not cause a deformation due to heat sagging of a heat curable resin, provides a barrier wall part of an ideal quadrangular or an inverse-tapered shape and, thereby, has a colored composition in each pixel being flat and having no color irregularity. SOLUTION: A barrier wall forming photoresist is applied on a substrate. Thereafter, by performing specified treatment for the substrate on which the photoresist is formed, only the outermost surface is modified in a photoresist layer. Further, the modified layer comes to be hardly dissolved into an alkaline developing solution. Therefore, the lower part of the barrier wall is preferentially developed, the barrier wall part is formed in a satisfactory inverse-tapered shape. When the barrier wall part is formed in a satisfactory inverse-tapered shape, a colored resin composition can be made flat. COPYRIGHT: (C)2007,JPO&INPIT
