Patent ID: 6841803

Claim:
A display device comprising: a light-emitting element for constituting pixels arranged in a matrix structure, the light-emitting element including a light-emitting layer, a light-reflecting surface disposed on a back surface of said light-emitting layer, a light polarization separating unit for separating light emitted from said light-emitting layer into two kinds of polarized light components by reflection and transmission; a retarder, and a polarizer; wherein said light polarization separating unit, said retarder and said polarizer are provided on a front surface side of said light-emitting layer; and said light polarization separating unit comprises a plurality of light polarization separating layers disposed on top of each other as separate layers of the light-emitting element and through which light in a wavelength range corresponding to light emitted from said light-emitting layer is separated into two kinds of polarized light components by reflection and transmission, said light polarization separating layers being laminated in a predetermined number corresponding to the number of colors of light emitted from said light-emitting layer.
