ABSTRACT:
A birefringent plate comprising a transparent substrate and an obliquely evaporated film formed on the transparent substrate, is free from the visual angle dependence because the obliquely evaporated film is formed into a multilayer composition and the neighboring layers have a different evaporation direction. Moreover, a manufacturing method for the birefringent plate, using a device constituted of a vacuum chamber and a crucible having a large number of inclined through holes, is capable of making the film thickness of the obliquely evaporated film uniform.
