Abstract
Disclosed is an active matrix substrate which includes a display area and a terminal area located outside the display area. The terminal area includes extraction wirings connected with signal lines and scanning lines of the display area. A testing terminal for making contact with a probe of a prober and a connection terminal on which a chip is mounted are provided on each of the extraction wirings. The terminals are connected with the extraction wirings through contact holes. Even when an area of the testing terminal is larger than an area of the connection terminal, an opening area of a second contact hole for the testing terminal is reduced to an area smaller than an opening area of a first contact hole for the connection terminal.
