Title:
COLORED RESIN COMPOSITION FOR COLOR FILTER, PIGMENT DISPERSION, COLOR FILTER, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/159634
Kind Code:
A1
Abstract:
Provided is a colored resin composition for a color filter, whereby a red pixel can be formed which satisfies a specific chromaticity and a specific phase difference. A colored resin composition containing a pigment including a red pigment represented by general formula (1), a dispersing agent including a copolymer having constituent units represented by general formula (2), a pigment derivative, an alkali-soluble resin, a monomer, an initiator, and a solvent, the colored resin composition for a color filter wherein the pigment derivative includes at least one species selected from a pigment derivative having a diketo-pyrrolo-pyrrole skeleton and a pigment derivative having an azo lake skeleton, the chromaticity (x, y) of the colored layer measured by a C light source when a colored layer of the colored resin composition is formed satisfies the expressions 0.630 ≤ x ≤ 0.665 and 0.326 ≤ y ≤ 0.335, and the phase difference (Rth) of light at a wavelength of 620 nm in the thickness direction of the colored layer is -30 nm to 120 nm. (The reference symbols in general formula (1) and general formula (2) are as indicated in the specification.)
