    Abstract: The reliability of a display device with an input device is improved. A plurality of detection electrodes (input position detection electrodes) forming an electrostatic capacity between them and a common electrode of a display device to detect an input position are formed on a different substrate from substrates configuring the display device. Moreover, a polarizing plate and the substrate on which the plurality of detection electrodes are formed are adhesively fixed via, for example, an adhesive layer so that the plurality of detection electrodes are fixed so as to be separated apart from the display device. Thus, a distance between electrodes (the detection electrode and a driving electrode) for detecting an input position can be set separately from a thickness of the display device, and therefore, reduction in detection sensitivity (detection reliability) for the input position due to increase in the electrostatic capacity can be suppressed.

    Abstract: In relation to touch sensors, technique capable of shortening total touch drive time and a touch detection period or suppressing increase thereof are provided. In a panel unit of a touch-sensor device, a touch drive unit generates a first pulse to an M-th pulses which are pulses of a plurality of types having mutually different cycles in accordance with differences in time constants with respect to paths including wirings of a peripheral area, touch drive electrodes, units of touch detection, touch detection electrodes, and wirings of the peripheral area through which pulses of touch drive signals to the plurality of touch drive electrodes are transmitted in a touch detection area in which the plurality of units of touch detection formed by pairs of the plurality of touch drive electrodes and the plurality of touch detection electrodes are formed like a matrix, and the touch drive unit applies the pulses.
