Laminated film

Abstract

A laminated film in which a plurality of layers are laminated includes: an end surface along a lamination direction; a light incident surface intersecting the end surface and allowing light from a light source to enter; a light guide layer configured to guide the light entering through the light incident surface; and a light extraction layer including a light extraction part configured to extract the light guided by the light guide layer. A thickness between a first surface and a second surface is 1,000 μm or less. The first surface is a surface of the light extraction layer on a side opposite to a side on which the light guide layer is disposed, and the second surface is a surface of the light guide layer on a side opposite to a side on which the light extraction layer is disposed.
