Claim:
1. A liquid crystal display device comprising: A TFT substrate including a terminal region and a display region on which a TFT and a pixel electrode are formed in a matrix arrangement, and a terminal formed in the terminal region on the TFT substrate, the terminal including: a first insulating film and a second insulating film formed on a terminal metal formed on the terminal region; a contact hole formed in the first insulating film and the second insulating film; and a first ITO formed in the contact hole and on the second insulating film, the terminal being connected to a different circuit through an anisotropic conductive film (ACF) including a conductive particle of a diameter d, wherein the first insulating film having an island region in the contact hole, wherein a second ITO is formed on the island region and formed between the island region and the first ITO, a portion where the terminal metal contacts the first ITO in the contact hole is formed to surround the island region, the portion having a width s, and the width s is smaller than the diameter d, the second ITO does not contact the terminal metal in the portion, and the second insulating film is not formed on the island region.
