摘要：
In causing an organic electroluminescent device to emit light upon exerting a voltage between a hole injection electrode and an electron injection electrode in the organic electroluminescent device, the frequency of electricity supplied to the organic electroluminescent device is modulated, to adjust the luminance of the light emitted from the organic electroluminescent device. In an organic electroluminescent apparatus and a display device in which the organic electroluminescent device is provided, there is provided frequency modulation means for modulating the frequency of electricity and supplying electricity to the organic electroluminescent device.
