Document Type and Number:
Japanese Patent JP4184189
Kind Code:
B2
Abstract:
The present invention provides light emitting displays which produce a bright image by efficiently emitting light radiated from a light-emitting thin-film layer to the viewer side, and also produces a high-quality image of high contrast ratio and changing in color to a limited extent over a wide viewing angle range even in a bright atmosphere. The light emitting displays are provided with a plurality of light-emitting devices 70, each device 70 having a light-emitting thin-film layer 100 and a light reflective surface 300 in this order on the back side, and a circularly polarized light reflective layer 500 which separates incident light into two types of circularly polarized components, one being reflected and the other transmitted by the reflective layer, an optical compensation layer 800, a quarter-wave plate 700 and a polarizer 600 on the front side, wherein the optical compensation layer 800 is composed of a transparent body working as an optical indicatrix having little refractive index distribution in the in-plane direction and having a refractive index in the thickness direction different from that in the in-plane direction.
