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: The plurality of stages of circuit blocks of a driver circuit in a display device include a first transistor and a second transistor. The first transistor is connected at its gate with a first node and controls conductivity between a scanning signal line and a first clock signal line applied with a first clock signal. The first node is at an active potential when at least any one signal of signals output from one stage in each of a forward direction and a reverse direction is at the active potential. The second transistor is connected at its gate with the first node and controls conductivity between the first clock signal line and an input signal line of another stage of circuit block.

Abstract: This invention envisages 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: A display device comprises counter electrodes configured to be used as common electrodes for displaying and scan electrodes for touch sensing, a first scan circuit which scans gate lines, and a second scan circuit which scans the counter electrodes. In the display device, one frame period includes a write period for continuously scanning one screen and a touch sensing period existing between the write period and a write period in the next frame. The second scan circuit includes a shift register unit and a switch unit. The switch unit includes a seventh thin-film transistor which outputs a DC drive signal to an output node and an eighth thin-film transistor which outputs an AC drive signal to the output node. A second control signal for fixing the voltage of a third retention node to which the gate electrode of the seventh thin-film transistor is connected is inputted in the write period.
