Abstract

An object is to provide a laminated film and a roll having excellent designability. The laminated film includes: a light guide element configured to guide light incident from a light source; and a low refractive index layer disposed on one side of the light guide element and having a refractive index of 1.30 or less. The light guide element includes a light extraction portion configured to extract light guided by the light guide element. The thickness of the light guide element is 1000 µm or less, and the total thickness from a first surface of the light guide element, which is the surface on the side opposite to the side on which the low refractive index layer is disposed, to a second surface of the low refractive index layer, which is opposite to the light guide element, is 1500 µm or less.
