Abstract: A pixel electrode is configured of one comb tooth portion and a contact portion whose width is widened from the end portion of the comb tooth portion in a first direction that is the extending direction of a scanning line. The width of the contact portion is not expanded in a direction opposite to the first direction, and the production of a domain is prevented. A picture signal line is bent in the direction in which the width of the contact portion of the pixel electrode is widened, so that the comb tooth portion of the pixel electrode can be disposed in the center between the picture signal lines, and the width of the contact portion can be formed in a sufficient width in the direction in which the picture signal line is bent. Thus, the contact margin of the pixel electrode can be provided.

Abstract: The purpose of the present invention is to prevent an overhang in a through hole in the display area when through holes in the organic passivation film in the display area and in the terminal area are simultaneously formed. The structure to realize this purpose is as follows: the terminal area having a lead wire, formed from a first metal, and extending to the display area, a first insulating film covering the lead wire, a second metal formed on the first insulating film, and a third metal formed on the surface of the second metal, wherein the first insulating film has a first through hole and a second through hole, the second metal has a first portion that connects with the lead wire via the first through hole, the second metal has a second portion that overlaps the second through hole, the second portion is separated from the first portion.

Abstract: A terminal structure that keeps the resistance of its connecting portion small and secures mechanical reliability is to be achieved. A display device includes a display region and a terminal region. A terminal formed in the terminal region is formed with a terminal metal, a first oxide conductive film covering the end portion of the terminal metal, and a second oxide conductive film covering the first oxide conductive film and the terminal metal. The first oxide conductive film has an opening in the center part of the terminal.
