    Abstract: To enable size reduction of a display device having a touch sensor function in which a display area has a non-rectangular shape. In a display area, video lines and common electrodes extend in the first direction, and scan lines extend in the second direction. A video signal transmission circuit and a common driver are arranged along a first edge of the display area, with which the one ends of the video lines are aligned. A scan line driver is arranged along a second edge of the display area, with which the ends of the scan lines and the common electrodes are aligned. The display area has a shape including an overlapping part between the first edge and the second edge. In a frame area adjacent to the overlapping part, the scan line driver is arranged more outward than the video signal transmission circuit and switch circuits.

    Abstract: This invention envisages having flexible wiring substrate terminals serving to connect with the wires for preventing dielectric breakdown caused by static electricity during the manufacturing process, and reducing the number of the flexible wiring substrate terminals. On a mother TFT substrate, signal lines extend over each liquid crystal cell in a manner flanking a scribe line between the adjacent liquid crystal cells. The signal lines of each liquid crystal cell are connected with connecting lines striding the scribe line. This reduces the number of static electricity countermeasure wires extending from the flexible wiring substrate terminals of each liquid crystal cell. Once completed, the individual liquid crystal cells are separated from one another, with no adverse effects caused by the connecting lines.

    Abstract: According to an aspect, a display device with a sensor includes: a substrate including a display region and a peripheral region on a periphery of the display region; detection electrodes arranged in a row-column configuration in the display region; and detection lines coupled to the respective detection electrodes. A shape of the substrate in a plan view includes a curve of a curved portion. The detection electrodes include a first electrode and a second electrode having a shape different from that of the first electrode in a plan view. The second electrode is juxtaposed with the curved portion. The detection lines each include a first line coupled to the first electrode and a second line coupled to the second electrode. The second line passes from the display region across the peripheral region and extends to a position overlapping with the second electrode in a plan view.
