Liquid crystal display device

A liquid crystal display device comprising:

• a pair of substrates disposed facing each other;
• a liquid crystal layer disposed between the pair of substrates;
• a seal member disposed between the pair of substrates and surrounding the liquid crystal layer to seal the liquid crystal layer;
• an electrode included in a first region of one substrate of the pair of substrates, the first region overlapping a region surrounded by the seal member;
• a first conductive film included in a second region of the one substrate, the second region being a region outside the seal member;
• a second conductive film included in the one substrate and extending from the electrode toward the first conductive film;
• a first insulating film disposed between the first conductive film and the second conductive film, the first insulating film including a contact hole in a portion of the second region overlapping the first conductive film, and the first conductive film and the second conductive film being electrically connected to each other through the contact hole;
• a second insulating film that covers the contact hole and is moisture-proof;
• a third conductive film included in the one substrate and disposed on a liquid crystal layer side with respect to the first conductive film and the second conductive film, the third conductive film connecting the first conductive film and the second conductive film, and the third conductive film being connected to the first conductive film through the contact hole;
• and
• a third insulating film disposed between the second conductive film and the third conductive film, the third conductive film including a second conductive film side contact hole in a portion of the second area overlapping the second conductive film, and the third conductive film and the second conductive film being electrically connected to each other through the second conductive film side contact hole,
• wherein the second insulating film covers the second conductive film side contact hole.
