MULTILAYERED FILM AND OPTICAL SHEET

摘要

A prism sheet as an optical functional sheet is a multilayer sheet, and includes a prism layer as an optical functional layer containing an organic material and a multilayer film. The multilayer film includes a film base and a first adhesive layer provided on the film base. The prism layer is formed on the first adhesive layer in a subsequent process. The thickness of the first adhesive layer is at least 0.1μm. The first adhesive layer contains at least 10 mass % of polyolefin.
