Abstract
The organic light emitting device of the present invention has a plurality of emission layers between an anode and a cathode, and the emission layers are separated from each other by an equipotential surface forming layeror a charge generating layer. The feature of the present invention resides in that the organic light emitting device has, at least either inside or outside the device, a light scattering means for scattering light emitted from the emission layers. The organic light emitting device can reduce the angle dependency of the emission brightness and the emission color by outputting the light emitted from the emission layers in a condition where the light is scattered by the light scattering means.
