Abstract
An organic EL display device includes: a transparent substrate; a circularly-polarizing plate disposed on a first surface of the transparent substrate; a wiring layer disposed on a second surface of the transparent substrate; a selectively-reflecting layer disposed on the wiring layer, where the selectively-reflecting layer reflects only a circularly polarized component, which has a predetermined wavelength and rotates in a predetermined direction, in incident light, and the selectively-reflecting layer transmits light of a wavelength different from the predetermined wavelength in the incident light and a circularly polarized component, which has the predetermined wavelength and rotates in a direction different from the predetermined direction; a transparent electrode disposed on the selectively-reflecting layer; an emission layer disposed on the transparent electrode in a position corresponding to the selectively-reflecting layer, where the emission layer emits light of a predetermined color; and a reflective electrode disposed on the emission layer.
