Abstract
[Problems] To provide a white or multicolor light emitting device that sufficiently contains components of various wavelength regions while having excellent brightness balance among the colors, and a method for producing such a light emitting device by a simple process. [Means to Solve the Problems] A light emitting device comprising, on a transparent substrate, a complementary color layer, a transparent electrode, an organic light emitting body and a reflective electrode. This light emitting device is characterized in that the organic light emitting body comprises at least a blue light emitting layer and a red light emitting layer, the complementary color layer absorbs a part of the light emitted from the organic light emitting body and emits green light, and the device emits white light from the transparent substrate side.
