Display device

A display device having a display area and a touch sensor, comprising:

• signal lines formed in the display area of a substrate, including a plurality of video lines extending in a first direction and a plurality of scan lines extending in a second direction intersecting the first direction;
• a plurality of common electrodes formed in the display area so as to extend in the second direction, for being used for video display and touch detection;
• a signal line laying area, in which the video lines and the scan lines are arranged, having a first edge and a second edge, the first edge being an edge with which the one ends of the video lines are aligned, the second edge being an edge with which ends of the scan lines and the common electrodes are aligned;
• a video signal transmission line for transmitting a video signal to one end of two ends of each of the video lines, the video signal transmission line being arranged on the substrate along the first edge and provided for every group obtained by divining the plurality of video lines into groups each including a plurality of adjacent video lines;
• a selector that is a circuit arranged between the video signal transmission line and the first edge, and connected, for every group, via an input thereof to the video signal transmission line, and via an output thereof to the video lines of the group,
• and
• a scan circuit and a common drive circuit arranged on the substrate along the second edge, the scan circuit for applying a scan signal to the scan line, and the common drive circuit for applying a reference potential signal or a touch detection signal to the common electrode,
• wherein
• the signal line laying area has a shape including an overlapping part where the first edge overlaps the second edge, and
• in a part of a frame area positioned outside the signal line laying area on the substrate, the part adjacent to the overlapping part, the scan circuit and the common drive circuit are arranged more outward than the selector.
