Abstract
A liquid crystal display apparatus includes a first polarizer located on one side of a first substrate, a second polarizer located on the opposite side of a second substrate, a liquid crystal layer formed of liquid crystal molecules and between the first and the second substrates so that the liquid crystal molecules may be aligned in parallel to the first or the second substrate and to which an electric field is applied in parallel to the first substrate, and a lighting device. The first or the second polarizer includes a polarization layer and supporting materials located on both sides of the polarization layer, reducing light leakage and a color shift in a black display state when viewed from the oblique direction.
