Abstract:
A liquid crystal display device, comprising:a pair of substrates disposed to oppose one another and fixed to one another by a sealing material maintaining a gap therebetween; a liquid crystal area being formed by sealing a liquid crystal in the gap which is surrounded by the sealing material; a plurality of pixel areas formed over a liquid-crystal-side surface of one of the pair of substrates in the liquid crystal area; and a plurality of signal lines for supplying signals to the plurality of pixel areas respectively, said signal lines being formed over the liquid-crystal-side surface of said one of the pair of substrates and extending from the liquid crystal area to a peripheral portion of the liquid-crystal-side surface beyond the sealing material; wherein at least one of the plurality of signal lines is covered with a stacked layered structure at the peripheral portion of the liquid-crystal-side surface, and the stacked layered structure is formed by stacking a first insulating film, a semiconductor layer, and a second insulating film on at least one of the plurality of signal lines in this order.
