Abstract
An electro-optical device includes an element substrate having a temperature detection conductive film formed by doping with an impurity in the same semiconductor layer as a semiconductor layer of transistor; and a driving portion for supplying a driving signal, wherein the driving portion includes a data conversion portion for converting image data and generating, as the driving signal, a digital driving signal made of an ON-voltage in which the brightness of the pixel is saturated and an OFF-voltage in which the pixel becomes a light-off state in each of a plurality of subfields in which a field period is divided on a time axis, and the data conversion portion performs a correction corresponding to a change in resistance in the temperature detection conductive film when generating the digital driving signal.
