Patent ID: 6975295

Claim:
A liquid crystal display device comprising: a liquid crystal; and two substrates opposed to each other with the liquid crystal interposed in between, the liquid crystal display device further comprising on a liquid-crystal-side surface of one of the two substrates: a plurality of gate signal lines; a plurality of drain signal lines that cross the plurality of gate signal lines; pixel regions each enclosed by two gate signal lines adjacent to each other and two drain signal lines adjacent to each other; a switching element that is provided in each pixel region and driven by a scanning signal supplied from one of the two gate signal lines that define the pixel region; a pixel electrode that is provided in each pixel region and supplied, via the associated switching element, with a video signal from one of the two drain signal lines that define the pixel region; an insulating film; a repair conductive layer formed so as to be contained in each of the plurality of drain signal lines when viewed perpendicularly and to be insulated from said each of the plurality of drain signal lines with the insulating film interposed in between; and a light shield film so formed along at least one side of the repair conductive layer that the light shield film is insulated from the repair conductive layer, the drain signal line and the pixel electrode, and that the light shield film is overlapped with the pixel electrode along an extending direction of the drain signal line.
