Abstract

A liquid crystal display that includes a first substrate, a second substrate facing the first substrate, liquid crystal disposed between the first substrate and the second substrate, wherein the liquid crystal is isotropic when no electric field is applied to the liquid crystal, and the liquid crystal is anisotropic when an electric field is applied to the liquid crystal, and an inner polarization layer formed on an inner surface of at least one of the first substrate and the second substrate.
