Image Display Element, Image Display Sheet, Image Display and Image Displaying Method

摘要

An image display element comprises a multilayer film optical filter in which layers of two or more types of materials which reflect or transmit therethrough light of a specific color and have different refractive indexs are alternately superimposed or stacked. The multilayer film optical filter is shaped like a fine particle. The multilayer film optical filter is, for example, a non-light-absorbing interference type color filter which reflects light having a predetermined color and transmits a complementary color of the predetermined color therethrough. Further, multilayer film optical filter is a dielectric multilayer film, a transparent resin multilayer film or a glass multilayer film.
