Abstract
The purpose of the invention is providing a current-input display device which can emit light at a constant luminance and provide a high definition display. According to the invention, a current which is almost the same as a current source can be inputted by adding a transistor in a pixel circuit, the circuit has a large output resistance enough not to be influenced by a change in I-V characteristic due to a deterioration of a light emitting element, a change in temperature and the like, and a high definition display can be obtained by conducting a correction if there are any influential changes in characteristics.
