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, as well as a color filter using the composition, and a method for manufacturing the same. Background technique [0002] Color filters are an indispensable component of liquid crystal displays. As a display device, the liquid crystal display is smaller than the CRT and has the same or higher performance. Therefore, as TV screens, personal computer screens and other display devices, CRTs are constantly being replaced. [0003] In recent years, the development trend of liquid crystal displays has shifted from the past monitor use with a small screen area to the TV use requiring a large screen and excellent image quality. [0004] With the increase in the size of the screen and the size of the substrate, the main technology used for the application of the photocurable composition on the substrat...
