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-bole 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.
