Claim Text:
1. A method for driving a display apparatus, the method comprising: charging an initialization voltage in a capacitive element of a pixel circuit; charging the capacitive element with a first data voltage determined based on a gray scale data voltage and a threshold voltage of a first transistor in the pixel circuit; and supplying a light-emitting element in the pixel circuit with current, corresponding to the first data voltage charged in the capacitive element, for causing the light-emitting element to emit light, wherein the first transistor controls a magnitude of the current supplied to the light-emitting element, and wherein the pixel circuit includes: a second transistor connected between a gate electrode of the first transistor and a first power supply, a third transistor having a first terminal connected to the gate electrode of the first transistor and a second terminal connected to a second terminal of the first transistor via the capacitive element, a fourth transistor connected between the second terminal of the first transistor and a second power supply, and a fifth transistor connected between the second terminal of the third transistor and a signal line supplied with the initialization voltage and the gray scale data voltage.
