摘要： A sampling transistor T1 is brought into conduction in accordance with a control signal supplied from a scanning line WS, and writes to a holding capacitor C1 a video signal supplied from a signal line SL. A driving transistor T2 outputs a driving current to an output node S in accordance with a signal potential of the video signal written to the holding capacitor C1. A switching transistor T3 is arranged between the output node S and a light-emitting device EL. In a predetermined light-emission period, the switching transistor T3 is in an on-state, and supplies the driving current to the light-emitting device EL to cause the light-emitting device EL to emit light at a brightness corresponding to the video signal. In contrast, in a non-light-emission period, the switching transistor T3 is turned off to disconnect the light-emitting device EL from the output node S, so that a potential generated at the output node S due to an operation of a pixel 2 performed in the non-light-emission period is prevented from being applied as a reverse-bias voltage to the light-emitting device EL of a diode type.

摘要： A pixel circuit having a function of compensating for characteristic variation of an electro-optical element and threshold voltage variation of a transistor is formed from a reduced number of component elements. The pixel circuit includes an electro-optical element, a holding capacitor, a sampling transistor, and a drive transistor. The sampling transistor samples and supplies an input signal from a signal line so as to be held into the holding capacitor. The driving transistor drives the electro-optical element with current in response to the held signal potential. The threshold voltage of the drive transistor is imparted to the holding capacitor in order to cancel an influence of the threshold voltage.
