Patent ID: 8471446

Claim:
An organic electroluminescent device comprising: a window; a polarizer placed below the window; resin placed between the window and the polarizer, and having a refractive index similar to that of the window and the polarizer; and a self-emissive layer placed below the polarizer, wherein the polarizer comprises: a polarization layer for linearly polarizing light incident from the outside and passing therethrough; a first wave plate for retarding a phase of the polarized incident light by a first predetermined amount; and a second wave plate for retarding the phase of the incident light having passed through the first wave plate by a second predetermined amount, and for further retarding the phase of reflected light having passed through the first and second wave plates and reflected back through the second wave plate by the second predetermined amount, wherein the first and second predetermined amounts are configured such that the reflected light is blocked by the first wave plate, wherein the first wave plate is formed so as to increase absorptance for a first range of visible wavelengths and increase transmittance for a second range of visible wavelengths, and wherein the second wave plate is formed so as to increase absorptance for the second range of visible wavelengths and increase transmittance for the first range of visible wavelengths.
