Patent number: 8711296Abstract: An active matrix substrate (30) of the present invention includes a substrate, a gate line (50) formed on the substrate, and an interlayer insulating layer (90) for insulating a layer formed on the gate line (50) from the gate line (50). In a region of the substrate, the interlayer insulating layer (90) is not provided on an upper surface of the gate line (50), and therefore, the upper surface is exposed. On the other hand, the insulating layer (90) is provided on the substrate so as to have contact with at least an edge face of the gate line (50) which edge face is on an extension of a longitudinal direction of the gate line (50).Type: GrantFiled: August 4, 2008Date of Patent: April 29, 2014Assignee: Sharp Kabushiki KaishaInventors: Tetsunori Tanaka, Atsushi Ban, Tohru Senoo, Wataru Nakamura, Yukimine Shimada

Publication number: 20110279766Abstract: A connecting terminal has a configuration in which a plurality of parts of a first line (2) and respective corresponding plurality of parts of a second line (6) are connected to each other by a transparent conductive thin film (10). In a connecting terminal part, the plurality of parts of the first line (2) and the respective corresponding plurality of parts of the second line (6) are connected to each other in parallel. With the configuration, it is possible to greatly reduce a risk of disconnection. It is therefore possible to prevent disconnection from being caused by corrosion in the connecting terminal part of a display apparatus etc.Type: ApplicationFiled: December 1, 2009Publication date: November 17, 2011Applicant: SHARP KABUSHIKI KAISHAInventors: Kenichi Kitoh, Wataru Nakamura, Tetsunori Tanaka, Takeshi Hara, Yuya Nakano

Publication number: 20110227085Abstract: The present invention is a substrate for use in a display panel. According to the substrate, lines (102, 106, 107, and 113) provided in a display region on the substrate are made up of multiple layers whose uppermost layers (102c, 106c, 107c, and 113c) are each made from (i) an oxide of first metal selected from the group consisting of copper, titanium, and molybdenum or (ii) a nitride of copper. This can prevent external light from being reflected and thereby improve a contrast in a bright room.Type: ApplicationFiled: November 5, 2009Publication date: September 22, 2011Applicant: SHARP KABUSHIKI KAISHAInventors: Wataru Nakamura, Kenichi Kitoh, Tetsunori Tanaka, Takeshi Hara, Yuya Nakano
