ABSTRACT:
An electro-optical device that displays a multiple viewing point image includes an electro-optical panel that has a plurality of pixels and includes at least a first substrate having transparency, a touch panel that detects contact in accordance with a change in electrostatic capacitance and includes a second substrate having transparency, a barrier layer that is formed on a face of the second substrate which is located on the first substrate side, has an opening part disposed in correspondence with an area between the adjacent pixels, and has a light shielding property, and a detection electrode that is formed on a face of the second substrate which is located on a side apart from the first substrate, has transparency, is used for detecting contact depending on a change in electrostatic capacitance. The second substrate and the first substrate are fixed with the barrier layer interposed therebetween.
