Abstract
To provide a liquid crystal display, particularly TN type liquid crystal display capable of remarkably improving brightness inversion resistance at a high contrast with a simple configuration and an optical compensation film which realizes the aforementioned properties, the liquid crystal display includes a pair of polarizing plates, each of the polarizing plates being disposed on an outer side of a liquid crystal layer having a twisted structure, the liquid crystal layer being disposed between substrates facing to each other, at least one of the substrates having an electrode, each of the polarizing plates including a polarizing film, a protective film, and an optical compensation film, wherein the optical compensation film includes a compound having a discotic structure unit, and the compound having a discotic structure unit is aligned such that the average alignment direction of the molecular major axis of the discotic structure unit at each side of the upper and lower optical compensation films facing to the polarizing film cross each other at an angle of not greater than the crossing angle of absorption axes of the pair of polarizing plates.
