To realize an organic electroluminescence element driving circuit capable of realizing application of reverse bias without almost increasing power consumption and cost. The connected relationship between a power supply potential Vcc and the GRD is changed by manipulating switches 21 and 22. With this arrangement, application of reverse bias to an organic electroluminescence element 10 is realized without newly preparing additional power supplies such as a negative power supply, and the like, whereby the life of an organic electroluminescence element 10 can be increased.
