Abstract:
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. An input signal is sampled from a signal line so as to be held in a holding capacitor. The threshold voltage of the drive transistor is imparted to the holding capacitor in order to cancel an influence of the threshold voltage.

Claim (Index 1):
A display apparatus comprising at least one of pixel including:\n an electro-optical element; a holding capacitor; a sampling transistor; a drive transistor; a first switching transistor; and a second switching transistor, wherein the sampling transistor has a first terminal connected to a signal line, a second terminal connected to a first terminal of the holding capacitor for passing an input signal voltage to the holding capacitor, and a gate terminal connected to a sampling scan line, wherein the first switching transistor has a first terminal connected to a power supply line, a second terminal connected to a first terminal of the drive transistor, and a gate terminal connected to a first scan line, wherein the second switching transistor has a first terminal connected to a first potential line, a second terminal connected to a second terminal of the drive transistor and a second terminal of the holding capacitor, and a gate terminal connected to a second scan line, wherein the drive transistor is configured to control a driving current from the power supply line to the electro-optical element depending on a potential held by the holding capacitor, the drive transistor having a threshold voltage that is imparted to the holding capacitor in association with the sampling transistor sampling the input signal voltage into the holding capacitor such that the potential held by the holding capacitor includes the input signal voltage and the threshold voltage, wherein a first reference potential is provided at a gate terminal of the drive transistor prior to a period that the threshold voltage of the drive transistor is imparted into the holding capacitor, and wherein a second reference potential is provided at the second terminal of the drive transistor prior to the period, the difference between the first reference potential and the second reference potential being greater than the threshold voltage of the drive transistor.
