Abstract
An electro-optical device includes a plurality of driving transistors turned on or turned off in accordance with a plurality of pulse-width modulation signals. An electro-optical element is electrically connected to drains of the plurality of driving transistors and emits light at a luminance corresponding to a drive current. A data signal generator generates a data signal in accordance with a plurality of pieces of data such that, the logical level of the data signal corresponds to the logical level of the corresponding pulse-width modulation signal for the corresponding section. Pulse-width modulation signal generators are provided for each respective driving transistors.
