Patent number: 11287934Abstract: 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.
