Abstract:
1. An organic electroluminescence device comprising a reflective element, an organic emissive layer, a phase plate, and a polarizer disposed directly on the phase plate, wherein polarization separators are provided between said organic emissive layer and said phase plate, said polarization separators reflect specific light components from both ambient and electrically stimulated light traveling from said organic emissive layer side and pass the remaining light, wherein said remaining ambient light is absorbed by said polarizer and a component of said remaining stimulated light is transmitted by said polarizer after conversion into a linear polarization by said phase plate, wherein said specific light is in a wavelength range that is narrower than the light-emission wavelength range of said organic emissive layer, said specific light includes a polarized light component which is absorbed by said polarizer after conversion into a linear polarization by said phase plate.
