Abstract: A flexible circuit film including a first flexible film, a second flexible film facing the first flexible film, and a plurality of wirings arranged between the first flexible film and the second flexible film. The wirings have different widths and bend in different directions, and a guide film including a material more rigid than the first and second flexible films is arranged on ends of the first flexible film. The guide film includes a tear-preventing portion overlapping with a bending portion of a shortest one of the wirings while covering portions of an inner edge near inner corners of a U-shaped flexible circuit film.
