A display device of the present invention has light-emitting devices
making up a plurality of pixels placed in a matrix form. In the display
device of the present invention, the light-emitting devices each
possesses an emissive layer and a reflective element placed on the rear
surface of the emissive layer; the emissive layer possesses at the said
of the front side, a polarization separator which separates the light
emitted from the emissive layer into two kinds of polarized components by
the reflection and the transmission, and phase plate; the emissive layer
substantially maintains the sate of the polarization of the light
transmitted there-through; the reflective element at least reflects the
circularly polarized light impinging in the vertical direction mainly as
a circularly polarized light having a reverse helicity direction; and the
polarization separator has a reflectance of the wavelength range from 520
nm to 600 nm smaller than a reflectance of range not more than 540 nm.
