Abstract:
An optical functional resin panel includes an injection molding resin, a base film, an ultraviolet curable hard coat layer provided on a surface of the base film, and a reflectance control layer provided on a surface of the hard coat layer, in which the reflectance control layer has a thickness variation of 10% or less, and the base film, the hard coat layer, and the reflectance control layer have a surface hardness increasing in this order.
