Patent ID: 8325118

Claim:
An electric current driving type display device comprising: a plurality of pixel circuits arranged so as to correspond to respective intersections of a plurality of scanning lines and a plurality of data lines; a scanning signal output circuit that selects a write-target pixel circuit using the scanning line; and a display signal output circuit that provides potentials according to display data to the data lines, wherein each of the pixel circuits includes: an electro-optical element provided between a first power supply wiring line and a second power supply wiring line; a drive element provided in series with the electro-optical element and between the first power supply wiring line and the second power supply wiring line; a capacitor having a first electrode connected to a control terminal of the drive element; a first switching element provided between a second electrode of the capacitor and the data line; a second switching element provided between the second electrode of the capacitor and a predetermined power supply wiring line; a third switching element provided between the control terminal and one current input/output terminal of the drive element; and a fourth switching element having a source terminal directly connected to a third power supply wiring line and having a drain terminal directly connected to the control terminal of the drive element, and wherein a potential that brings the drive element into a conduction state is applied to the third power supply wiring line.
