  • Organic EL display element having optical stack
    Patent number: 9588271
    Abstract: An organic EL display device includes at least a polarizer layer, a ?/2 plate, a ?/4 plate and an organic EL panel in this order, and an in-plane retardation Re2(550) of the ?/4 plate at 550 nm satisfies 115?Re2(550)?155, and an in-plane retardation Re1(550) of the ?/2 plate at 550 nm satisfies Re1(550)=2×Re2(550)±50 nm.

  • Optical film, polarizing plate, image display device, and 3D image display system
    Patent number: 8896789
    Abstract: Disclosed is an optical film in which a minute interference unevenness is reduced. The optical film comprises a transparent film having a thickness of 10 ?m to 150 ?m, and a first layer and a second layer, in this order, on the transparent film, wherein values of in-plain mean refractive indices thereof satisfy the formula: the second layer>the first layer>the transparent film; the difference in in-plane mean refractive indices between the first layer and the second layer and the difference in in-plane mean refractive indices between the first layer and the transparent film are each 0.02 or more; and the optical thickness D of the first layer satisfies the formula: 270×N?150?75 nm?D?270×N?150+75 nm (1?N?8 where N is a natural number).
