ABSTRACT:
The present invention provides an organic electroluminescence element driving circuit that is capable of realizing application of reverse bias without increasing power consumption and cost. The connected relationship between a power supply potential Vccand the GRD is changed by manipulating switches. With this arrangement, application of reverse bias to an organic electroluminescence element can be realized without newly preparing additional power supplies such as a negative power supply, and the like, whereby the life of an organic electroluminescence element can be increased.
