ABSTRACT:
The present invention relates to a liquid crystal display, comprising a lower alignment film formed on a lower substrate; an upper alignment film formed on an upper substrates; 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 10-20° 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 0.24-0.27 μm, the phase compensation film has a phase compensation function of λ/4 and also has an optical axis making 140-146° with a horizontal line and the polarizer has an absorption axis making 120 to 122.5° with a horizontal line.
