摘要： [Problems to be Solved] To provide a multilayered phase difference plate that obtains a higher incident light polarization conversion efficiency than that of a related-art multilayered phase difference plate.[Means to Solve the Problems] There is provided a multilayered phase difference plate 1 that serves as a half-wavelength phase difference plate in the range of 400 nm to 700 nm by bonding together a first phase difference plate 10 and a second phase difference plate 20 in a manner that optical axes 11 and 12 intersect each other. The multilayered phase difference plate 1 obtains a higher incident light polarization conversion efficiency than that of a related-art multilayered phase difference plate, since the respective plate thicknesses of the first and second phase difference plates 10 and 20 are within the range such that the phase difference deviation amounts are offset by each other.

摘要： A polarization separating element is configured to include a translucent substrate formed of a crystal material having birefringent properties and optically rotatory power and a polarization separating portion formed on the incidence-side surface of the translucent substrate so as to transmit a P-polarized light beam and reflect an S-polarized light beam. A reflecting element that reflects the S-polarized light beam reflected by the polarization separating portion is disposed so as to be separated approximately in parallel to the translucent substrate. A predetermined function is set such that the P-polarized light beam having passed through the polarization separating portion and been incident to the translucent substrate is converted so as to be parallel to the polarization plane of the S-polarized light beam so that the P-polarized light beam is output as the S-polarized light beam.

A phase difference plate is disposed at an emission-side of the transmissive substrate. The P-polarized light, which is transmitted through the polarization separation portion and is incident to the transmissive substrate, is made to be emitted from an emission-side surface of the transmissive substrate while maintaining a polarization plane thereof, and the polarization plane of the P-polarized light transmitted through the transmissive substrate is converted to be as S-polarized light in the phase difference plate.
