Patent ID: 7868854

Claim:
An electro-optical device comprising: a plurality of data lines; a plurality of scanning lines; and a plurality of unit circuits that are provided in correspondence with intersections of the data lines and the scanning lines, wherein each of the data lines is supplied with a data voltage in accordance with a gray-scale level, wherein each of the scanning lines is supplied with a scanning signal that specifies a writing period during which the data voltage is being written into the corresponding unit circuits, and wherein each of the plurality of unit circuits includes: a driving transistor that generates a driving current in accordance with an electric potential of a gate of the driving transistor; an electro-optical element that generates light with a gray-scale level in accordance with the driving current that is generated by the driving transistor; a capacitive element that has a first electrode and a second electrode that is connected to the gate of the driving transistor; a power feed line that is supplied with a constant electric potential and is, during an initialization period that is different from the writing period, electrically connected to the second electrode; a first switching element that electrically connects the gate of the driving transistor with a drain of the driving transistor to conduct current to the gate of the driving transistor during the entire initialization period; and a second switching element that switches between conduction and non-conduction between the data line and the first electrode on the basis of the scanning signal.
