Patent ID: 7928935

Claim:
An electro-optical device, comprising: a plurality of data lines; a plurality of scan lines; and a plurality of unit circuits disposed to correspond to respective intersections of the plurality of data lines and the plurality of scan lines, wherein each of the plurality of data lines is supplied with a data potential corresponding to a level of gray scale and each of the plurality of scan lines is supplied with a scan signal which defines a writing period in which the data potential is loaded to the corresponding unit circuit, wherein each of the plurality of unit circuits, includes: a drive transistor for generating a driving current corresponding to a potential of a gate thereof; an electro-optical element displaying a level of gray scale corresponding to the driving current; a capacitive element having a first electrode and a second electrode; an electric supply line which is electrically connected to the second electrode of the capacitive element in an initialization period other than the writing period and which is supplied with a predetermined potential; a control line having a first control line wiring, a second control line wiring, a light-emitting control line wiring and a scan line wiring corresponding to one of the plurality of scan lines; the electric supply line extends in a direction so as to not intersect the control line; a first switching element for electrically connecting the gate and a drain of the drive transistor to each other during at least the initialization period; a second switching element for controlling electrical connection and disconnection between the data line and the first electrode of the capacitive element on the basis of the scan signal, a third switching element for controlling electrical connection and disconnection between the electric supply line and the first electrode of the capacitive element and for electrically connecting the electric supply line and the first electrode of the capacitive element to each other during at least the initialization period, wherein the second electrode of the capacitive element is connected to the gate of the drive transistor and the electric supply line extends in a direction so as not to intersect the scan line, the third switching element is in an on-state when the second switching element is in an off-state, and the third switching element is operated on the basis of the scan signal.
