Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an ink material for a red color filter having high contrast and excellent heat resistant crystallinity. SOLUTION: The ink material for the red color filter comprises a resin component which includes a curable resin (A), a polymerization initiator (B), and a colorant (C) as main components, and which is dissolved in a solvent (D). The curable resin (A) is composed of an epoxy (meth) acrylate compound (A-1), a polyfunctional acrylate (A-2), and a polyfunctional monomer or oligomer (A-3) having at least two or more reactive groups selected from a group of an epoxy group, an isocyanate group, an amino group, and an amine group in a molecule. The polymerization initiator (B) is a photo-polymerization initiator (B-1) or a thermal polymerization initiator (B-2). A pigment included in the colorant (C) is a mixture of three kinds of pigments, that is, a diketopyrrolopyrrole-based pigment, an anthraquinone-based pigment, and a nickel Azo Yellow-based pigment.
