DISPLAY DEVICE
First Claim
1. A display device comprises a first circuit including:
- a first electrode formed on a first substrate having a display surface of a display panel;
a field effect transistor formed on a second substrate opposed to said first substrate so that said first electrode is spaced from the field effect transistor on a back channel side, a gate terminal being connected to a first wiring, and a first drain/source terminal being connected to a second wiring; and
a switch, one end thereof being connected to a second drain/source terminal of said field effect transistor, and the other end being connected to a third wiring.

Abstract
Provided is a display device provided with a non-contact type touch sensor having excellent properties, in place of a contact-point type touch sensor. The display device includes a first circuit having a first electrode (62c) formed on a first substrate (2) having a display surface of a display panel, a field effect transistor formed on a second substrate (1) opposed to the first substrate (2) so that the first electrode (62c) is spaced from the field effect transistor on the back channel side, a gate terminal of the field effect transistor being connected to a first wiring (Vrstn) and a first drain/source terminal thereof being connected to a second wiring (Vsm), and a switch, one end of which is connected to a second drain/source terminal of the field effect transistor and the other end being connected to a third wiring (Vom).
