Abstract
An organic light emitting diode (OLED) has a plurality of light emitting regions. The OLED includes an anode layer, a cathode layer, an organic light emitting layer, and a wavelength shift layer. The organic light emitting layer is disposed between the anode layer and the cathode layer and correspondingly provides the light emitting regions with a plurality of emitted lights. Here, the organic light emitting layer has a fixed thickness. The wavelength shift layer is disposed outside the organic light emitting layer, the cathode layer, and the anode layer. A wavelength range at half-peak of combination of the emitted lights is wider than a wavelength range at half-peak of one of the lights.
