ABSTRACT:
A liquid crystal display device is provided which improves the angle of view characteristics over that of a conventional OCB type LCD, has a high transmissivity, and can be driven at a low voltage. The liquid crystal display device includes two optical phase difference compensating mechanisms interposed between two substrates and two filter mechanisms, each of which compensating mechanisms has an action for performing compensating modulation on light passing through about one half the thickness of said liquid crystal layer, wherein the product of anisotropy .DELTA.n of the liquid crystal layer and its thickness d is preferably 0.8<.DELTA.nd<2.0.
