    Abstract: This invention aims at reducing the probability of short-circuiting between terminals in a display device in which an IC driver is connected by COG. Terminals for connection with the IC driver are formed in a terminal region of a TFT substrate. The terminals are each comprised of a terminal metal, a first through-hole formed in a first insulation film, a second through-hole formed in a second insulation film, a first ITO formed in the first through-hole and being in contact with the terminal metal, and a second ITO formed over the first ITO. The second ITO is formed within an area where the second ITO is in contact with the first ITO but is not formed outside the second through-hole. This ensures that the distance between the ITOs of the adjacent terminals can be enlarged, whereby the probability of short-circuiting between the terminals can be lowered.

    Abstract: It is possible to reduce a size of a lower frame region to ensure a wiring corrosion margin equivalent to that of a conventional technique. In a display device, a video signal wiring arranged in the lower frame region includes, in a region between a terminal section (terminal) and a video signal line, a first wiring formed on a first wiring layer and having one end connected to the terminal section to which a video signal line driving circuit is connected, a second wiring formed on a second wiring layer different from the first wiring layer and having one end connected to the other end of the first wiring, and a third wiring formed on the first wiring layer and having one end connected to the other end of the second wiring. The other end of the third wiring is connected to the video signal line via a fourth wiring formed on the second wiring layer, and the first wiring layer is formed on the side closer to an array substrate than to the second wiring layer.
