Abstract:
1. A display device comprising blue, green, and red light-emitting devices making up a plurality of pixels placed in a matrix form, wherein the blue, red, and green light-emitting devices each comprise: a reflective element, an emissive layer, a phase plate, and a polarizer in this order, and further comprise a polarization separator between the emissive layer and the phase plate, which separates light into two kinds of polarized light components by reflection and transmission, and a dividing wall between the light-emitting device and an adjoining one of the light-emitting devices, wherein the polarization separator has a reflectance of the wavelength range from 520 nm to 600 nm smaller than a reflectance of wavelength range not more than 510 nm, and wherein the dividing wall serves as means for preventing the reflection of the light having a wavelength corresponding to the wavelength range at which the polarization separator reflects.
