Abstract

An electro-optical device includes a plurality of pixel portions formed in a display region on a substrate, a first light-receiving element which is formed in the display region and shows light-receiving sensitivity with respect to an incident visible ray which enters a display surface, a second light-receiving element which is formed in the display region and shows light-receiving sensitivity with respect to an incident infrared ray which enters the display surface, and a detecting unit which detects a pointing unit which points the display surface on the basis of the light-receiving sensitivity with respect to the incident visible ray and the light-receiving sensitivity with respect to the incident infrared ray.
