Abstract
A liquid crystal display device is composed of a liquid crystal cell having TN liquid crystal, a pair of polarizing plates arranged on both sides of the cell comprising a polarizer and a pair of protective films provided both sides of the polarizer and an optical compensatory sheet between the cell and the polarizing plate. The optical compensatory sheet comprises at least two optically anisotropic films having optically negative uniaxial property, one film having an optic axis in the direction of the normal of the film and other film having an optic axis in a direction inclined at 5-50 degrees from the normal, and the sum of retardation value of the film having an optic axis in the direction of the normal and retardation values of two protective films existing between the polarizers is from 100 to 400 nm.
