More Information
Summary:Provided is a depolarizing plate having a superior degree of depolarization to conventional depolarizing plates. The depolarizing plate includes a light-transmitting substrate having a surface layer portion in which a fine pattern is provided that includes a plurality of curved lines randomly disposed at a pitch of no greater than a wavelength of light, and that exhibits structural birefringence.
