Abstract
An object of the present invention is to provide a film in which generation of multiple images is suppressed in a case of being applied to AR glasses. The film according to the embodiment of the present invention is a film including at least one or more light-absorbing anisotropic layers, in which an angle between a transmittance central axis of the light-absorbing anisotropic layer and a normal direction of the light-absorbing anisotropic layer is 0° to 45°, and a maximum height difference of undulation in a region of 10 mm× 10 mm on a film surface is 1.2 μm or less.
Claims20
A film comprising:
