PROBLEM TO BE SOLVED: To provide a light emission device provided with a feedback system for correcting emission luminance according to a purpose by detecting light emission of a light-emitting part with a light-receiving part. SOLUTION: This light emission device is provided with a light-emitting part 4 to 6 and a light-receiving part 3 and controls the luminance of the light emitting part by detecting a part of light emission of the part 3 with the light- receiving part 3. The light emitting part is provided with a light-emitting layer 5 which is held between a pair of electrodes 4, 6 in which at least one side of the electrodes is light transmissive, and the light-receiving part 3 is provided at a position, where it can directly receive a part of the light emission to be emitted from the light-emitting part through the light transmissive electrode 4. |
