A display device includes a driving transistor for supplying driving current to a display element; a first switch connecting the driving transistor to a corresponding data line; a second switch selectively connecting a control electrode of the driving transistor to one of two main electrodes of the driving transistor; and a third switch connecting the driving transistor to the display element in one pixel. The first switch is controlled by a first control line. The second and third switches each include two switching elements connected in series controlled by the first control line and a second control line, respectively. Four functions of writing of data in the pixel, light emission of the display element by supplying current, non-light emission of the display element, and examination of the pixel operation can be switched using the two control lines.
