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. By for example, laminating a black matrix, a color filter layer, a color conversion layeror the like on a transparent substrate, and above thereof, combining an optical filterhaving a minute concave-convex surface, with an endless number of minute concave-convex by a pitch of the wavelength of the light or less formed, with an organic EL element, the object can be achieved.
