Patent ID: 6947105

Claim:
A polarized-light emitting organic electroluminescent device comprising an organic electroluminescent element and a polarized-light scattering film which comprises a light-transmitting resin and dispersedly contained therein minute regions differing from the light-transmitting resin in birefringent characteristics and in which the difference in refractive index between the minute regions and the light-transmitting resin in the axis direction in which a linearly polarized light has a maximum transmittance, Δn 1 , is smaller than 0.03 and that in a direction perpendicular to the Δn 1 direction, Δn 2 , is from 0.03 to 0.5, the light produced by the organic electroluminescent element being emitted from the device through the polarized-light scattering film, the polarized light being emitted from the device through the polarized-light scattering film; wherein the minute regions of the polarized-light scattering film which are dispersedly contained in the light-transmitting resin are formed by phase separation and have a Δn 2 -direction length of from 0.5 to 50 μm as measured in the Δn 2 -direction.
