Organic electro-luminescence diode
An organic electro-luminescence diode comprises two electrodes and an organic electro-luminescence structure. The organic electro-luminescence structure is formed between the two electrodes, and includes a red light-generating unit, a green light-generating unit, a blue light-generating unit and a light-compensating unit stacked with each other. The light-compensating unit is selected from the group consisting of a white light-compensating unit, a red light-compensating unit, a green light-compensating unit, a blue light-compensating unit and a structure stacking together one light-compensating unit upon the other.
