Claim Text:
1. A liquid crystal display that drives liquid crystal molecules laterally with a lateral electric field, comprising: a thin film transistor substrate with a plurality of pixel regions arranged in a matrix; an opposite substrate with a color filter arranged in a position corresponding to those of said pixel regions; and a liquid crystal held between said thin film transistor substrate and said opposite substrate arranged to face each other, said thin film transistor substrate including a source line and a gate line arranged to cross each other in a grid pattern, and a thin film transistor arranged at the intersection between said source line and said gate line, said source line being covered with an insulating film and the insulating film being covered with a first alignment film, said opposite substrate including a protrusion arranged so as to protrude toward said thin film transistor substrate, wherein said protrusion is entirely composed of an insulating material, with said thin film transistor substrate and said opposite substrate arranged to face each other, said protrusion being arranged so as to overlap said source line from above and to extend in a direction in which said source line extends, said protrusion having a conductive film arranged directly on an edge surface of said protrusion near said source line, said protrusion and said conductive film being covered with a second alignment film, said conductive film arranged nearer to said source line than said opposite substrate.
