POLARIZED LIGHT SEPARATING FILM, METHOD OF MANUFACTURING POLARIZED LIGHT SEPARATING FILM AND LIQUID CRYSTAL DISPLAY APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a polarized light separating film which is excellent in polarized light separating performance and which can be manufactured by a simple process and to provide a method of manufacturing the polarized light separating film and a liquid crystal display apparatus.;SOLUTION: The polarized light separating film has a substrate comprising a transparent longitudinal resin film on a surface of which a plurality of rows of groove sections extending substantially in parallel with each other are formed and a light absorbing thin film layer formed so as to cover the whole surface of the substrate including the groove section when seen from a position facing a substrate surface. Further the polarized light separating film satisfies following conditions (1) to (5) in a perpendicular cross section. (1) 0.1δ(h₀-h₁), (2) n₁≥2.5 or k₁≥1.5, (3) a parameter θ showing an inclination of the groove section is between 60° and 90°, (4) d(λ₀/n₀), (5) 0.1dt0.8d, wherein h₀ denotes depth of the groove section, h₁ denotes thickness of the light absorbing thin film layer, δ denotes a calculated value:λ₀/(2π²n₁²k₁)^1/2 respectively.;COPYRIGHT: (C)2007,JPO&INPIT
