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 () formed on a first substrate () having a display surface of a display panel, a field effect transistor formed on a second substrate () opposed to the first substrate () so that the first electrode () 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).
