Abstract:
A display device with a touch detection function including: a plurality of elements performing display operation; a plurality of touch detection electrodes arranged side by side to extend in one direction, and each outputting a detection signal based on a change in an electrostatic capacitance caused by an external proximity object; a conductive film insulated from or connected with high resistance to the touch detection electrodes, and disposed to cover the touch detection electrodes; and a touch detection circuit detecting the external proximity object by sampling the detection signal. The conductive film has a sheet resistance equal to or smaller than a predetermined resistance value, and has a time constant larger than a predetermined minimum time constant defined by sampling timings in the touch detection circuit.

Claim (Index 1):
A display device with a touch detection surface, the display device comprising:\n a pixel substrate; a plurality of pixel electrodes on an upper surface of the pixel substrate; an opposed insulating layer having a lower surface facing the pixel substrate and an upper surface facing away from the pixel substrate; an outermost layer that constitutes the touch detection surface; a plurality of display elements between the pixel substrate and the opposed insulating layer; a common electrode that is disposed between the opposed insulating layer and the display elements and that overlaps the plurality of display elements; a plurality of detection electrodes for touch detection on the opposed insulating layer, an electrostatic capacitance being formed at the detection electrodes; a conductive layer that is insulated from or is connected with high resistance to the detection electrodes; and a polarizing layer, wherein,\n on an upper surface side of the opposed insulating layer are sequentially stacked (a) the detection electrodes, (b) the conductive layer, and (c) the polarizing layer, \n the conductive layer has (a) sheet resistance value that is sufficiently low to allow the conductive layer to provide an effective electrostatic discharge path and (b) an RC time constant larger than a predetermined minimum time constant defined by sampling timings in a touch detection period, and \n in a vertical direction perpendicular to the opposed-insulating layer, a distance from the touch detection surface to the detection electrodes is larger than a distance from the touch detection surface to the conductive layer.
