Abstract:
1. A liquid crystal display apparatus comprising a liquid crystal device which includes a first substrate having a first transparent electrode a second substrate having a second transparent electrode and a nematic liquid crystal layer which is twisted-oriented by an STN-twist angle between the first and second substrates; a first polarization board provided outside of the first substrate; a twisted phase difference board provided outside of the second substrate and having liquid crystal polymer layers; and a second polarization board provided outside of the twisted phase difference board; wherein: the direction of the twist angle of molecule orientation of the twisted phase difference board is reverse to the direction of the twisted orientation of the liquid crystal molecule of the liquid crystal devices, and the absolute value of the twist angle of the twisted phase difference board is smaller than the absolute value of the twist angle of the liquid crystal devices by 10° to 40°.
