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.
