Abstract: An active matrix substrate (20a) includes a gate electrode (25) formed on an insulating substrate (10a), and a planarizing film (26) formed on the gate electrode (25) and made of a baked SOG material. The gate electrode (25) is a multilayer film including a first conductive film (27) formed on the insulating substrate (10a) and made of a metal except copper, a second conductive film (28) formed on the first conductive film (27) and made of copper, and a third conductive film (29) formed on the second conductive film (28) and made of the metal except copper.

Abstract: 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.

Abstract: 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.

Abstract: A method for manufacturing a display device includes; a first step of preparing a plastic substrate placed on a support substrate, a second step of bonding a first region of an expanded silicone sheet to an end of the plastic substrate, and bonding a second region of the silicone sheet to the support substrate having the plastic substrate placed thereon, thereby fixing the plastic substrate to the support substrate by a biasing force of the silicone sheet, and a third step of laminating a plurality of thin films over the plastic substrate fixed to the support substrate.
