Abstract:
1. An electro-optical device comprising: an element substrate having a pixel including a pixel electrode for driving a liquid crystal, and a transistor for switching the pixel provided in correspondence with the pixel electrode, and a temperature detection conductive film formed by doping with an impurity in the same semiconductor layer as a semiconductor layer of the transistor; and a driving portion for supplying a driving signal for displaying a gray scale to the pixel electrode, 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, wherein
