ABSTRACT:
An input-capable display device includes a first substrate a second substrate, a detection electrode, a dielectric film, and a detector. A pair of electrodes that drive a liquid crystal layer are provided on the first substrate. The second substrate is opposed to the first substrate through the liquid crystal layer. The detection electrode and the dielectric film are laminated on an outer surface of the second substrate. The detector detects a position at which an electrostatic capacitance is formed with the detection electrode through the dielectric film. The second substrate includes a shield conductor that is provided on a side adjacent to the liquid crystal layer. An electric potential of the shield conductor is fixed. The shield conductor has a plurality of birefringent structures that are arranged in a stripe.
