Abstract

Provided are a colored curable resin composition and a color filter and a display device using the same, the colorant-curable resin composition comprises a colorant, resin, polymerizable compound andpolymerization initiator; the colorant contains C.I. Pigment blue 16 and yellow colorant, is free of green colorant; the C.I. Pigment blue 16 content is 26% or more in f the 100% colorant by mass, andthe polymerization initiator contains an oxime compound.

Description

technical field [0001] The present invention relates to a colored curable resin composition, a color filter, and a display device. Background technique [0002] In recent years, developments to expand the color reproduction range that can be displayed in liquid crystal display devices have progressed, and as part of this, color filters with more intense colors are being sought. [0003] For example, in Recommendation Rec. ITU-R BT.2020 specifying the Super Hi-Vision (SHV) image format, the color reproduction region is further expanded. Therefore, a color filter with a high Rec.ITU-R BT.2020 color gamut inclusion rate (the ratio of the color region that can be expressed in the color reproduction region to the color reproduction region of Rec.ITU-R BT.2020) is high is what people are after. [0004] As a method of thickening the color of a color filter, the method of raising the density|concentration of the coloring agent in a color filter is mentioned. However, if the conc...
