Abstract: An object of the present invention is to solve the problem of losing a part of the incident light due to the irregular reflection of the incident light if a layer containing fine particles is formed by coating for the purpose of roughing when providing measures to prevent the reflection of the light at the surface of the color filter layer or at the surface of the color conversion layer inside a display, or a problem of difficulty in management of the paint for obtaining a certain roughened surface or a problem of increase of the number of processes to prevent the reflection when preventing the reflection by laminating plural layers of different refractive indices.

Abstract: An optical filter having a laminated body which is laminated on a transparent substrate. The laminated body has at least a color filter layer. The laminated body has a minute concave-convex surface formed on a surface of the laminated body opposite from the transparent surface.

Abstract: The main object of the present invention is to provide an inexpensive color filter substrate for an organic EL element and an organic EL display device which are capable of displaying good images having no defects such as dark spots. To attain the object, the invention provides a color filter substrate for an organic EL element having a substrate, a colored layer formed in a pattern form on/over the substrate, and a transparent electrode layer and a conductive layer laminated, in any order, on/over the colored layer, wherein the conductive layer is a coated film.
