Abstract:
1. A light emitting circuit for making an organic electroluminescence element emit light in response to a light emission instruction, comprising: a first diode element connected with the organic electroluminescence element in a same polarity direction in series, a second diode element connected with said organic electroluminescence element at a connection point between said organic electroluminescence element and said first diode element, in a direction contrary to the polarity direction of the first diode element, driving current supplying means for supplying a driving current for light emission in the forward polarity direction to the serial circuit of said organic electroluminescence element and said first diode element in response to the light emission instruction, and reverse bias application means for applying a voltage to the serial circuit of said organic electroluminescence element and said second diode element in the direction contrary to the forward polarity direction of said organic electroluminescence element when said organic electroluminescence element does not emit light.
