Abstract:
An electro-optical device includes a plurality of unit circuits; a first selecting circuit that sequentially selects the plurality of unit circuits; and a first signal line through which correction data for the individual unit circuits are supplied serially. Each of the plurality of unit circuits includes an electro-optical element that exhibits an intensity corresponding to a driving current, a storage circuit that obtains correction data from the first signal line when the first selecting circuit selects the unit circuit and that stores the correction data; and a control circuit that controls the driving current supplied to the electro-optical element according to intensity data specifying the intensity exhibited by the electro-optical element and the correction data stored in the storage circuit.
