Claim Text:
1. A display device having a capacitive touch sensor, comprising: a first substrate; a second substrate facing the first substrate; a display function layer having an image display function, the display function layer being interposed between the first substrate and the second substrate; a plurality of display pixel electrodes; a common electrode facing the display pixel electrodes, the display pixel electrodes and the common electrode being disposed between the first substrate and the display function layer; a control circuit that performs an image display control by applying a voltage for display between the display pixel electrode and the common electrode, based on an image signal, so that the display function of the display function layer is exhibited; a touch detection electrode of the capacitive touch sensor, the touch detection electrode and the common electrode being arranged such that a capacitance is formed between the common electrode and the touch detection electrode; and a touch detection circuit that detects a position touched by an object based on a detection signal obtained from the touch detection electrode, wherein, the touch detection electrode is between the second substrate and the display function layer, and the second substrate is interposed between a first polarizing plate and the first substrate.
