Abstract
The color filter of the present invention is particularly suitable for a color liquid crystal display (1). Colored pixels (8, 9 and 10) each made of a transparent resin material having a pigment dispersed therein are formed on a transparent substrate (6). The color filter has a protective film (11) formed over the colored pixels by curing a coating film of a photopolymerizable resin composition containing at least a photopolymerizable acrylate oligomer and a multifunctional photopolymerizable acrylate monomer having at least two functional groups in one molecule. The color filter is superior in both heat resistance and light resistance and also excellent in display quality.
