ABSTRACT:
A HAN-mode liquid crystal display includes a lower alignment film formed on a lower substrate; an upper alignment film formed on an upper substrate; a liquid crystal layer sandwiched between the lower and upper substrates; a phase compensation film adhered on the outer surface of the upper substrate and a polarizer adhered on the phase compensation film wherein the lower alignment film has an alignment angle of −40 to −50° with respect to a horizontal line, the upper alignment film has an alignment angle of 40 to 55° with respect to a horizontal line, the liquid crystal layer has a phase delay value (dΔn) of 0.36–0.40 μm, the phase compensation film has a phase compensation function of λ/4 and also has an optical axis making 167–173° or 7 to 13° with a horizontal line and the polarizer has an absorption axis making an angle of 42 to 48° with a horizontal line.
