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.
