ABSTRACT:
A novel liquid crystal display is disclosed. The display comprises a pair of substrates disposed facing each other and at least one of which has an electrode, a liquid-crystal layer being sandwiched in between the pair of substrates and comprising liquid-crystal molecules aligned along with a first alignment axis and a second alignment axis respectively formed on facing surfaces of the first and second substrates, a pair of polarizing plates disposed sandwiching the liquid-crystal layer, and at least an optically anisotropic layer disposed between the liquid-crystal layer and either of the polarizing plates, and comprising at least one liquid crystal compound which is aligned along with a third alignment axis and is fixed in the alignment state. And their disposition satisfies at least one of Condition (1): the alignment axes of the substrates are not parallel to transmission axes of the polarizing plates; and Condition (2): the alignment axis of the substrate is not parallel to the alignment axis of the optically anisotropic layer.
