Title:
METHOD FOR PRODUCING WAVELENGTH PLATE
Document Type and Number:
WIPO Patent Application WO/2011/162331
Kind Code:
A1
Abstract:
Disclosed is a method for producing a wavelength plate, by which a wavelength plate that has excellent durability and stability, while maintaining high moisture resistance can be produced. Specifically, a dielectric material is obliquely vapor deposited on a substrate so as to form a birefringent layer (14) that has columnar portions (12), in each of which fine particles of the dielectric material are laminated in a columnar shape, and gap portions (13) that are respectively formed between two columnar portions (12). The thus-formed birefringent layer (14) is subjected to an annealing treatment at a temperature within the range of 100-300˚C (inclusive). Following that, a protective film (15) with low water vapor permeability is formed on the annealed birefringent layer (14) by forming an inorganic compound on the birefringent layer (14) at high density.
