An electro-optical device includes an electro-optical element that includes a first electrode, a second electrode, and an electro-optical material pinched by the first and second electrodes of which the optical characteristic is changed in accordance with supply of a predetermined electric potential, a position detecting unit that detects a position of an object, which is brought into contact with an image displaying surface that displays an image configured by the electro-optical element, on the image displaying surface, and a physical amount measuring unit that is included in the position detecting unit and measures a predetermined physical amount of the whole or a part of the image displaying surface for a case where the object is brought into contact with the image displaying surface. The position detecting unit detects the position of the object on the image displaying surface based on the measurement result of the physical amount measured by the physical amount measuring unit and based on the measurement result from which the measurement result measured by the physical amount measuring unit at an inversion time of the polarity of an electric potential difference between the first electrode and the second electrode is excluded.
