Claim Text:
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 on coordinates as indicated by an object to be detected, the touch panel substrate including: the position detecting electrode is provided between the insulating substrate and the electro-optic element driving electrode and being insulated from the electro-optic element driving electrode, the position detecting electrode includes a plurality of first electrodes arranged along a first direction and a plurality of second electrodes arranged along a second direction perpendicular to the first direction and insulated from the first electrodes, the metal wires are provided on a different level from the first electrodes and the second electrodes, the metal wires make bridge connections between the first electrodes so as to bridge between the second electrodes along the first direction, the metal wires include first metal wires electrically connected with the first electrodes via first contact holes defined in an insulating layer provided between the first metal wires and the first electrodes, second metal wires electrically connected with the second electrodes via second contact holes defined in the insulating layer provided between the second metal wires and the second electrodes, and metal wiring portions which are not electrically connected to the first electrodes and the second electrodes, the first metal wires define bridge connections between each separate one of the first electrodes and other ones of the first electrodes via at least one of the first contact holes, the first electrodes and the second electrodes are provided in a same plane, in the lane in which the first electrodes and the second electrodes are provided the second electrodes are connected via transparent connection wires, the first metal wires and second metal wires have disconnections between the first contact holes and the second contact holes, so that no electricity travels between the first electrodes and the second electrodes, the metal wiring portions are located between the first contact holes and the second contact holes and located between the first metal wires and the second metal wires, and the electro-optic element driving electrode and the position detecting electrode are located between the air of substrates.
