摘要： There is provided a multilayered phase difference plate 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 and a second phase difference plate in a manner that their respective optical axes intersect each other. The multilayered phase difference plate obtains a high incident light polarization conversion efficiency because the respective plate thicknesses of the first and second phase difference plates are within a range such that phase difference deviation amounts become offset by each other.
