Abstract: An inspection circuit is properly protected in a display device, in which a driver IC is not on a terminal area. A liquid crystal display device includes a TFT substrate including a display area, in which video signal lines are formed, and a terminal area. A counter substrate overlaps with the display area of the TFT substrate. The counter substrate and the TFT substrate are adhered by a seal material, and the display area is formed in an area surrounded by the seal material. The flexible wiring circuit substrate connects to the terminal area. The driver IC, which supplies video signals to the video signal lines, is not installed in the terminal area. An inspection circuit is formed between the display area and the terminal area, and the inspection circuit overlaps with the counter substrate in a plan view.

Abstract: In an IPS-mode liquid crystal display device, the area of a terminal portion is decreased. A liquid crystal display device includes a TFT substrate and a counter substrate attached to the TFT substrate with a sealing material, and includes a display region and a terminal portion formed on the TFT substrate. A shielding transparent conductive film is formed on the outer side of the counter substrate. On the terminal portion, an earth pad formed with a transparent conductive film is formed on an organic passivation film. The shielding transparent conductive film is connected to the earth pad through a conductor. Below organic passivation film of the terminal portion, a wire is formed.

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 extend in the first direction, and scan lines and common electrodes extend in the second direction. A video signal transmission circuit is 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 part of the frame area adjacent to the overlapping part, the scan line driver is arranged more outward than the video signal transmission circuit.
