Title:
OPTICAL COMPENSATION PLATE
Document Type and Number:
WIPO Patent Application WO/2014/050408
Kind Code:
A1
Abstract:
Provided is an optical compensation plate to which dust and dirt tend not to adhere. An optical compensation plate (10) has a substrate (11), a phase difference compensation layer (12), and an antireflection layer (14). The substrate (11) is, for example, a glass substrate. The phase difference compensation layer (12) is formed by oblique vapor deposition of an inorganic material onto the surface of the substrate (11) and has a fine structure in which oblique columnar structures stand close together in large numbers on the surface of the substrate (11). The antireflection layer (14) is provided above the phase difference compensation layer (12) and has concavo-convex structures uniformly formed all over the surface.
