Patent ID: 7098970

Claim:
A liquid crystal display device comprising: a pair of substrates; a liquid crystal sealed between said pair of substrates; a plurality of data lines and a plurality of scanning lines, being arranged on one surface of one of said pair of substrates and crossing each other; a switching element having one end of a current path connected to a data line and a control end connected to a corresponding first scanning line; a wiring connected to the other end of the current path of said switching element, said wiring extending to and overlapping a second one of said plural scanning lines; an insulating layer, being formed on said wiring and having a contact hole through which an end portion of said wiring is exposed; a pixel electrode, being formed on said insulating layer and electrically connected to the end portion of said wiring through the contact hole; and an alignment film, being formed on said pixel electrode and in contact with said liquid crystal, wherein said contact hole is formed at a position overlapping a region where disclination occurs, wherein said insulating layer is formed of a plurality of laminated insulating films, the insulating films have openings individually which form said contact hole in a tapered shape as a whole, and wherein said insulating films includes a passivation film formed on the switching element, a color layer formed on said passivation film, and a flattening film formed on said passivation film and color layer, said contact hole includes openings formed in the passivation film, the color layer, and the flattening film, respectively, and the openings being formed in a tapered shape as a whole.
