Photosensitive colored resin composition and color filter and display device using same

The invention relates to a photosensitive colored resin composition and a color filter and a display device using the same. The photosensitive colored resin composition includes a solid composition portion and a solvent. The solid composition portion includes a colorant, an alkali-soluble resin, a polymerizable unsaturated compound, a photopolymerization initiator, and scattering particles. The scattering particles in the solid composition portion have a scattering area ratio alpha. D is the average particle size of the scattering particles, and the unit is nm. The sphericity is the sphericity of the scattering particles. R is the roundness of the scattering particles. And C is the weight percentage of the scattering particles in the solid composition part. 60 nmlt; dlt; the wavelength is 250nm. 500 lt; 500 lt; [alpha] [lt]; 3000, 3000. 感光性着色树脂组成物及应用其的彩色滤光片与显示装置。感光性着色树脂组成物包括固态组成物部分以及溶剂。固态组成物部分包括着色剂、碱可溶性树脂、聚合性不饱和化合物、光聚合起始剂以及散射粒子。固态组成物部分中散射粒子具有散射面积比率α。d为散射粒子的平均粒径，单位为nm。为散射粒子的球形度。R为散射粒子的圆度。C为散射粒子占固态组成物部分的重量百分比。6
