1. An electro-optical device, comprising:
- an electro-optical panel including a first substrate, a second substrate, and an electro-optical substance interposed between the first and the second substrates;
a third substrate arranged on the second substrate;
a fourth substrate made from glass and arranged on the third substrate via a spacer;
a position detector provided on the third substrate and detecting a pressed position on the fourth substrate based on changes in surface waves generated on the third substrate;
a resin film provided on the fourth substrate and opposed to the third substrate; and
a resin plate arranged on the fourth substrate, the fourth substrate having a first side and a second side opposing the first side, the resin film being provided on the first side, the second side having a depressed part in which the resin plate is disposed, the depressed part substantially corresponding to a touch area.

13. An electro-optical device, comprising:
-
an electro-optical panel including a first substrate, a second substrate, and an electro-optical substance interposed between the first and the second substrates; a touch panel substrate facing the second substrate of the electro-optical panel, and having a coordinate input area where a user actually conducts input; a position detector provided on the second substrate or on another substrate disposed between the electro-optical panel and the touch panel substrate, the position detector detecting a pressed position on the touch panel substrate based on changes in surface waves generated on the touch panel substrate; a resin film disposed on a first side of the touch panel substrate, the first side facing the second substrate; a resin plate disposed on a second side of the touch panel substrate, the second side opposing the first side, wherein the touch panel substrate has a thick portion and a thin portion, the thick portion being supported by the third substrate via a spacer, the thin portion corresponding to the coordinate input area, at least a part of the resin plate being disposed at the thin portion, and wherein Young'"'"'s modulus of the resin film is smaller than that of the touch panel substrate and smaller than that of the resin plate. - View Dependent Claims (14, 15, 16)
