A liquid crystal display device having suitable structures for avoiding the decline in the yield factor for production thereof by preventing signal lines formed therein from being disconnected. A liquid crystal display device has a pair of substrates confronting one another and being spaced by a liquid crystal layer and at least one first signal line, a first insulating film, at least one second signal line, and a second insulating film being formed above a surface of one of the pair of substrates. The at least one first signal line and the at least one second signal line are arranged so as to cross one another at a crossing region, where the at least one first signal line, the first insulating film, the at least one second signal line, and the second insulating film are disposed in this order from the surface of the one of the pair of the substrates. The second insulating film has a pair of openings piercing therethrough at both sides of the crossing region and a conductive layer is formed thereon. The conductive layer crosses over the at least one first signal line and electrically connected to the at least one second signal line via the pair of openings at both sides of the crossing region.
