Abstract

An inspection device of the present invention is provided with a light source unit which is disposed either one of a base material side and a light diffusing portion side and irradiates light toward a light-regulating film with respect to the light-regulating film which includes a base material, a light diffusing portion, and a light shielding layer, and a light receiver which is disposed on either the other of the base material side and the light diffusing portion side and measures an intensity of transmitted light which is emitted from the light source unit and is transmitted through the light-regulating film, and inspects a state of an inclined surface of the light diffusing portion based on a measurement result of the intensity of the transmitted light.
