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.
