COLOR MATERIAL DISPERSION, COLORED RESIN COMPOSITION AND CURED PRODUCT THEREOF, COLOR FILTER, AND DISPLAY DEVICE

Provided is a color material dispersion which has excellent dispersibility and high storage stability even in the case where a definite lake color material and a phthalocyanine pigment are mixed at a ratio within a desired range and which is capable of forming a colored layer showing improved adhesion to a substrate and enhanced coating film uniformity. The color material dispersion comprises a color material, an acidic dispersant and a solvent, wherein the color material comprises a specific lake color material and a basic treated phthalocyanine pigment and the acidic dispersant comprises a polymer having a specific acidic phosphorus compound group and a salt thereof. 本发明提供一种色材分散液，其即便将规定的色淀色材与酞菁颜料在所期望的范围内混合，分散性与保存稳定性仍优异，且能够形成基板密合性与涂膜均匀性提高的着色层。本发明的色材分散液含有色材、酸性分散剂及溶剂，色材包含特定的色淀色材及经碱性处理的酞菁颜料，且上述酸性分散剂包含具有特定的酸性磷化合物基及其盐的聚合物。
