The invention provides an organic electroluminescent element driving circuit to which a reverse-bias is applied, which does not require a substantial increase in power consumption an increase in layout space. With switches arranged, electroluminescent elements are set to be in a reverse-bias state. The pixels are reverse-biased on the basis of a group of predetermined pixels at a time, for example, the pixels are reverse-biased on a pixel-by-pixel basis or on a line-by-line basis, or all pixels are reverse-biased at a time. In this way, reverse bias can be applied without the need for an additional power source, and without requiring a substantial increase in power consumption nor an increase in layout space. The service life of the organic electroluminescent element can thus be prolonged.
