BIAXIAL BIREFRINGENT COMPONENT, LIQUID CRYSTAL PROJECTOR, AND METHOD FOR MANUFACTURING BIAXIAL BIREFRINGENT COMPONENT

摘要

A phase compensator having a biaxial birefringent component (40) is fabricated by oblique deposition of an inorganic material on a base plate (69). A polar angle of an evaporation path of the inorganic material is controlled in a predetermined angular range to a surface normal of the base plate (69). In the oblique deposition process, the base plate (69) is oscillated in a horizontal direction. The phase compensator is arranged such that its slow axis (L4) is perpendicular to a slow axis (L3) of tilt components (24a, 24b) in a liquid crystal panel (20), and that an index ellipsoid (41) is tilted in an opposite direction to a tilt direction of the tilt components (24a, 24b).
