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