Abstract
An organic EL display device includes at least a polarizer layer, a λ/2 plate, a λ/4 plate and an organic EL panel in this order, and an in-plane retardation Re2(550) of the λ/4 plate at 550 nm satisfies 115≦Re2(550)≦155, and an in-plane retardation Re1(550) of the λ/2 plate at 550 nm satisfies Re1(550)=2×Re2(550)±50 nm.
