Abstract
A film structure, a method for manufacturing the film structure, a shell, and an electronic device are disclosed. The film structure includes a first film assembly and a second film assembly. The first film assembly includes a first film and a texture layer stacked sequentially. The second film assembly includes a second film and a ribbon unit disposed on the second film. The second film assembly is laminated on the first film assembly. The ribbon unit is located adjacent to the first film, and an orthographic projection of the ribbon unit projected on a plane on which the texture layer is located falls in the texture layer.
