Abstract
A color conversion filter substrate includes a transparent support substrate, one or more types of color conversion layers with a thickness more than 5 μm formed on the support substrate in a desired pattern, and a protective layer formed of a transparent material for covering the support substrate and the color conversion layers and having a flat surface. After a display is produced, the color conversion pattern layers contain unsaturated functional groups at a concentration equal to or less than 1.4×10−3 mol/g.
Claims5
A color conversion filter, comprising:
- a transparent support substrate,
- at least one color conversion layer formed on the support substrate in a specific pattern, said color conversion layer containing unsaturated functional groups at a concentration equal to or less than 1.4×10−3 mol/g after the color conversion filter is assembled, and
- a transparent protective layer for covering the color conversion layer and a surface of the transparent support substrate on which the color conversion layer is formed.
