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.
