Abstract
A liquid crystal display includes a first display panel including a first substrate and a lower alignment layer formed on the first substrate, a second display panel that includes a second substrate facing the first substrate to maintain a predetermined cell gap between the substrates and an upper alignment layer formed on the second substrate, a liquid crystal layer provided between the first and second display panels, a wide view polarizer and a lower polarizer sequentially attached to the outside of the first display panel, and an upper polarizer attached to the outside of the second display panel. An absorption axis of the wide view polarizer is inclined with respect to an absorption axis of the lower polarizer by 45°. An absorption axis C′ inclined with respect to the absorption axis A′ of the lower polarizer by 45° is interposed between the lower polarizer and the liquid crystal panel in the backlit electrically controlled birefringence (ECB) mode.
