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: A display device with a variant-shape display region other than the rectangular display region is configured to form a scanning line drive circuit along the variant-shape display region. The scanning line drive circuit includes bus wiring group with clock wiring for supplying clocks with three or more phases and the power supply wiring for supplying power, and the unit circuits for configuring the shift register including five or more transistors. The bus wiring and the unit circuits are formed on the different regions so as not to cross with one another.

Abstract: A display device includes pixel electrodes formed in an image display area of a substrate, a common electrode formed in the image display area, inside signal lines formed inside the image display area, and electrically connected to the pixel electrodes, outside signal lines formed outside the image display area, and electrically connected to the inside signal lines, and a common line formed inside and outside the image display area, and electrically connected to the common electrode. An image is displayed under a control of a light using an electric field developed between the pixel electrodes and the common electrode. A coupling capacitance is formed between the inside signal lines and the common electrode. The outside signal lines each include a first portion, and a second portion higher in electric resistance than the first portion and the inside signal lines.

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.
