Abstract:
1. A liquid crystal display device, comprising: first and second substrates sandwiching therebetween a liquid crystal layer; a first polarizer disposed at an outer side of said first substrate away from an inner side thereof facing said liquid crystal layer; and a second polarizer disposed at an outer side of said second substrate away from an inner side thereof facing said liquid crystal layer; said liquid crystal layer comprising a liquid crystal having a negative dielectric anisotropy in such a manner that molecules of said liquid crystal are aligned generally perpendicularly to said first and second substrates in a state in which an external electric field is not applied, said first polarizer and said second polarizer being disposed such that an optical absorption axis of said first polarizer and an optical absorption axis of said second polarizer cross with each other perpendicularly, wherein there is disposed an optically biaxial retardation film having refractive indices n wherein said optically biaxial retardation film provides an in-plane retardation having a magnitude defined by |n wherein said in-plane retardation of said optically biaxial retardation film has a value of 20 nm or more but not exceeding 80 nm.
