Abstract:
A display device having a scanning line, a data line, a power supply line, and a pixel. The pixel having a first transistor supplied with a selecting pulse of a scanning signal, a holding capacitor having a first electrode and a second electrode that holds an image signal from the data line and the first thin film transistor. The pixel also having a second transistor controlled by the image signal, a gate of the second transistor being electrically connected to the second electrode, and a luminescent element provided between a pixel electrode and an opposite electrode opposed to the pixel electrode driven by current that flows between the pixel electrode and the opposite electrode. A potential of the gate electrode of the second transistor being able to be shifted by supplying to the first electrode of the holding capacitor with a predetermined signal after the selecting pulse becomes non-selective.
