    摘要: The present invention provides an organic light emitting device which can reduce the angle dependency of the emission brightness and the emission color, and has a small change in the emission brightness and the emission color with respect to film thickness fluctuations, and can increase use efficiency of the light. The organic light emitting device of the present invention has a plurality of emission layers 3 between an anode 1 and a cathode 2, and the emission layers 3 are separated from each other by an equipotential surface forming layer 4 or a charge generating layer 4. 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 5 for scattering light emitted from the emission layers 3. 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.
