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.
