Abstract:
1. A liquid crystal display which comprises: a lower substrate having a reflective electrode; a lower alignment film formed on the lower substrate; an upper substrate having a color filter and disposed opposite to the lower substrate; an upper alignment film formed on the 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 serving to convert linearly polarized light into circularly polarized light; and a polarizer adhered on the phase compensation film and serving to convert natural light from the external into linearly polarized light; wherein the lower alignment film has an alignment angle of 0 to 10° with respect to a horizontal line; the upper alignment film has an alignment angle of 50 to 56° with respect to a horizontal line; the liquid crystal layer has a phase delay value (dΔn) of 0.17-0.21 μm; the phase compensation film has a phase compensation function of λ/4 and also has an optical axis making an angle of 135 to 145° with a horizontal line; and the polarizer has a absorption axis making an angle of 62 to 66° with a horizontal line.
