Abstract
A main object of the present invention is to provide a high-quality color filter wherein the shapes of colored layer, as individual pixels, are even in the whole. To achieve the object, the present invention provides a color filter comprising: a base material; a light shielding part formed on the base material and containing a light shielding material and a resin; a photocatalyst containing layer formed to cover the base material and the light shielding part and containing a photocatalyst and an organopolysiloxane; and a colored layer formed on the photocatalyst containing layer in opening portions made in the light shielding part, wherein regarding ten pixels out of its pixels, the film thickness of a maximum film thickness portion where the film thickness from the surface of the base material to the surface of the colored layer in the opening portion in the pixel is maximum and the film thickness of a minimum film thickness portion where the film thickness from the surface of the base material to the surface of the colored layer in the opening portion is minimum are measured in each pixel, and the ratio α between the average A of the film thicknesses of the maximum film thickness portions and the average B of the film thicknesses of the minimum film thickness portions in the ten pixels (=B/A) is in the range of 0.5 to 1.0.
