Patent ID: 8552949

Claim:
An electro-optical device comprising: a first scanning line; a second scanning line; a data line; a first pixel circuit including: a first driving transistor having a first gate, a first drain, and a first source; a first electro-optical element of which brightness is set according to a state of conduction between the first drain and the first source; and a first switching element that is controlled by a first scanning signal supplied through the first scanning line; and a second pixel circuit including: a second driving transistor having a second gate, a second drain, and a second source; a second electro-optical element of which brightness is set according to a state of conduction between the second drain and the second source; and a second switching element that is controlled by a second scanning signal supplied through the second scanning line, the electro-optical device being configured such that: a first setting of a level of a first gate voltage of the first gate to a first voltage level is carried out by electrically connecting the first gate to any one of the first drain and the first source; a first supply of a first data signal to the first gate through the data line and the first switching element is carried out; a second setting of a level of a second gate voltage of the second gate to a second voltage level is carried out by electrically connecting the second gate to any one of the second drain and the second source; and at least a part of the first supply and at least a part of the second setting being carried out simultaneously.
