Patent ID: 6947112

Claim:
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 −10 to 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 an angle of 140 to 146° with a horizontal line; and the polarizer has a absorption axis making an angle of 120 to 122.5° with a horizontal line.
