Patent ID: 7300828

Claim:
A method of manufacturing a liquid crystal display device which holds a liquid crystal layer between an active matrix substrate and a counter substrate, the method comprising the steps of: forming an insulating film above the active matrix substrate; forming a plurality of conductive patterns on the insulating film by patterning a conductive film formed on the insulating film; forming a photoresist film which has an outline shape that corresponds to an outline shape of the plurality of conductive patterns and covers at least the plurality of conductive patterns, and which photoresist film additionally contacts and covers the insulating film in vicinities immediately adjacent the covered conductive patterns, and which photoresist film overlays portions of conductive residual patterns extending across the conductive patterns; and etching portions of the residual patterns which are not covered by the photoresist film, are outside the outline shape of the photoresist film, and exist above the active matrix substrate by using the photoresist film as a mask.
