Abstract:
Provided is an organic EL display device in which blue brightness is improved, and an antireflection function in an oblique direction is enhanced. The problem is solved by ensuring that a polarizer, a phase difference layer, a circularly polarized light separating layer, and a light emitting element are provided from a viewing side, an in-plane retardation Re(550) of the phase difference layer is set to 100 to 160 nm, the circularly polarized light separating layer is a cholesteric liquid crystal layer having a selective reflection center wavelength in a range of 425 to 475 nm, and a sum of retardations Rth(550) in a thickness direction of members arranged between the polarizer and the light emitting element is set to −50 to 50 nm.
