1. An electro-optic device comprising:
- an electro-optic element; and
a pair of substrates between which the electro-optic element is provided,one of the pair of substrates being a touch panel substrate that is provided with a position detecting electrode which detects, according to a change in capacitance, a position given by coordinates indicating an object to be detected, the touch panel substrate comprising;
an insulating substrate;
an electro-optic element driving electrode which applies an electric field to the electro-optic element; and
the position detecting electrode, the position detecting electrode being provided between the insulating substrate and the electro-optic element driving electrode and being insulated from the electro-optic element driving electrode, whereinthe position detecting electrode including at least a plurality of first electrodes which are arranged along a first direction and each of which is made up of a transparent electrode,the first electrodes at least being electrically connected to a grid of metal wires via an insulating layer,the metal wires also serve as a light blocking layer, andthe electro-optic element driving electrode and the position detecting electrode are located between the pair of substrates.
