Abstract: A liquid crystal display device includes a bank on a first substrate and surrounding an image display area, a first alignment film on the first substrate, a second alignment film on a second substrate, and a sealing member to seal the liquid crystal material between the first and the second alignment films. The bank has a shape in which a slope of an inside surface standing from an inner peripheral lower end on a side of the image display area is steeper than a slope of an outside surface standing from an outer peripheral lower end on an opposite side to the image display area. The first alignment film contacts the inside surface of the bank and is provided in the image display area. The sealing member passes over the outside surface of the bank in a direction toward the inside surface and overlaps the bank.

Abstract: A shielding metal of an adjacent liquid crystal panel separated from a mother substrate remains at an outer end part of a terminal portion of a liquid crystal display panel. The shielding metal has a two-layered structure including first shielding metals arranged at predetermined pitches and second shielding metals arranged at predetermined pitches. An insulating layer is provided between the first and the second shielding metals. This makes it possible to prevent short-circuit in wirings on a flexible wiring substrate even if the wirings on the flexible wiring substrate are brought into contact with the first or the second shielding metal.
