Abstract

There are provided: a curable resin composition having a high exposure sensitivity and a good developing property, and thereby capable of forming an accurate and precise pattern; a liquid crystal panel substrate on which a protective film for covering a color layer or spacers for a liquid crystal layer, by using the curable resin composition, hardly causing a color irregularity and contrast irregularity; and a liquid crystal panel using the liquid crystal panel substrate and having a superior display quality. The curable resin composition of the present invention comprises: a copolymer (a) having a molecular structure in which a constitutional unit including an acidic functional unit and a constitutional unit including a photocurable functional group are linked at least; a photopolymerization initiator (h) having a tertiary amine structure; and a photocurable compound (c) having at least one acidic functional group and at least three photocurable functional groups.
