Patent ID: 8212947

Claim:
A liquid crystal device comprising: a liquid crystal panel including: a pair of substrates; and a vertically-aligned liquid crystal interposed between the pair of substrates; a pair of polarizing films that interposes the liquid crystal panel therebetween; a first retardation film that is disposed between the pair of polarizing films, the first retardation film including: a first substrate; a vertically-deposited film maintaining a uniaxial refractive anisotropy and having a vertically deposited inorganic material on the first substrate so that a uniaxial optical axis of the uniaxial refractive anisotropy is parallel to a thickness direction; and a first deposited film maintaining a first refractive anisotropy and having an obliquely deposited inorganic material on the vertically-deposited film so that a first optical axis of the first refractive anisotropy is tilted in a first direction, the first refractive anisotropy being biaxial; and a second retardation film that is disposed between the pair of polarizing films, the second retardation film including: a second substrate; and a second deposited film maintaining a second refractive anisotropy and having an obliquely deposited inorganic material on the second substrate so that a second optical axis of the second refractive anisotropy is tilted in a second direction different from the first direction, wherein at least one of the pair of polarizing films is rotatable about a normal direction of the first retardation film, and wherein the first retardation film is rotatable about the normal direction of the first retardation film, the first retardation film being rotatable independent of the at least one of the pair of polarizing films such that the vertically-deposited film is rotatable only in conjunction with the first deposited film.
