Provided is a display panel including: a plurality of pixel electrodes divided into a plurality of groups; and a plurality of common electrodes arranged at a ratio of one to a plurality of pixel electrodes included in one of the plurality of groups. Each of a plurality of sensor electrode lines overlaps with corresponding one of a plurality of data signal lines in plan view. The plurality of sensor electrode lines and each of the plurality of common electrodes overlap each other in plan view. The each of the plurality of common electrodes is electrically connected to the plurality of sensor electrode lines. At least one insulating film is formed between each of a region between the data signal lines and the sensor electrode lines, a region between the sensor electrode lines and the common electrodes, and a region between the common electrodes and the pixel electrodes.

Display panel with touch detection function

An input device which is a capacitive coupling type and can reduce visibility of wiring patterns of electrodes and interference fringes is provided. The input device is included in a display device including a plurality of pixels, and is configured to detect a contact position of a user. The input device includes a plurality of first electrodes, a plurality of second electrodes disposed so as to cross the first electrodes, and a plurality of third electrodes disposed between the second electrodes. Slits extending obliquely with respect to an extension direction of the second electrodes are formed between the third electrodes.
