Abstract

See full text

An O plate is included which includes a phase difference compensating layer which is an assembly of columns obtained by oblique deposition of an anisotropic refractive index medium with respect to a substrate and has negative biaxial refractive index anisotropy. In the O plate, a front surface phase difference value of the O plate in the normal direction is 5-15 nm, and a ratio of Re(−30)/Re(30) is 2.5-5.5.
