Abstract
Official abstract text for this publication.
An object of the present invention is to provide a colored resin composition, which is useful in production of a color filter suitable for an organic EL display device, excellent in low temperature curability, and also excellent in red color reproducibility. The present invention relates to the colored resin composition containing a colorant, a resin, a polymerizable compound, and a polymerization initiator, wherein the colorant is composed of only pigments, and the pigments include C.I. Pigment Violet 29, a red pigment and a yellow pigment.
