Abstract

In a photo curable composition including colorant, alkali-soluble resin, polymerize compound, initiators for photopolymerization and solvent, the average grain diameter of the colorant is smaller than 150 nm, the alkali-soluble resin and / or polymerize compound have alkylene oxide chains. The solvent kind with boiling point above 200 DEG C and the solvent kind with boiling point below 200 DEG C are respectively including at least one solvent. The total sum (Sigma T multiplies X) of the product (T multiplies X) of the boiling points T (DEG C) between the solvent kinds and the content X (mass%) relative to the solvent total amount is 120x10<2>-190x10<2> (DEG C%).

Description

technical field [0001] The present invention relates to a photocurable composition suitable for producing color filters used in liquid crystal display elements and solid-state imaging elements, a color filter using the composition, and a method for producing the same. Background technique [0002] A color filter is an indispensable component of a liquid crystal display. As a display device, a liquid crystal display is smaller than a CRT, and its performance is equal or higher. Therefore, CRTs are constantly being replaced as TV screens, personal computer screens, and other display devices. [0003] In recent years, the development trend of liquid crystal displays has been shifting from the traditional monitor application with a small screen area to the TV application which requires a large screen and excellent image quality. [0004] With the enlargement of the screen and the enlargement of the size of the substrate, the coating of the photocurable composition on the subst...
