1. An electro-optic device comprising an electro-optic panel and a touch panel, whereinthe electro-optic panel includes:

  • a first electro-optic panel substrate;

    a second electro-optic panel substrate arranged so as to face to the first electro-optic panel substrate; and

    an electro-optic substance sandwiched between the first electro-optic panel substrate and the second electro-optic panel substrate, andthe touch panel includes;

    a second touch panel substrate arranged on an opposite surface of the first electro-optic panel substrate with respect to the electro-optic substance, and having a second surface;

    a first touch panel substrate arranged a fixed distance away from the second touch panel substrate via spacers, having a first surface that faces the second surface and having a flexibility, and the first touch panel substrate having an input surface;

    a position detecting section formed on the first surface and arranged in a corner portion of the first surface, and detecting a position where the first touch panel substrate is being pressed based on changes in surface acoustic waves generated on the first surface;

    a resin film formed directly on the second surface of the second touch panel substrate; and

    a plurality of projections formed on a surface of the resin film, whereina recessed portion is formed on an opposite surface of the first touch panel substrate with respect to the second touch panel substrate, anda first polarization plate is arranged on the recessed portion, and whereinthe first touch panel substrate is bent in a direction of the second touch panel substrate as a result of the input surface of the first touch panel substrate of the touch panel being pressed, and the bent portion of the first touch panel substrate comes into contact with the resin film provided on the second touch panel substrate.
