Abstract:
A blue curable resin composition includes a colorant (A), a resin (B), a polymerizable compound (C) and a polymerization initiator (D). The colorant (A) includes two or more pigments each having a phthalocyanine backbone. The blue curable resin composition has relatively low in Bx and is high in intensity in an xy chromaticity diagram of an XYZ color system. A color filter may be formed from the blue curable resin composition. The blue curable composition may be also used in a display device.
