发明名称 Liquid crystal display apparatus with optical compensation plates
摘要 A first optical compensation plate consists of M (M being an integer equal to or greater than 2) optical compensation layers. A second optical compensation plate consists of N (N being an integer equal to or greater than 2) optical compensation layers. A liquid crystal display panel has (M+N) liquid crystal layers. The liquid crystal layers are made of materials having optically different polarities from those of the first and second optical compensation plates. Further, the direction of the optic axis of a j-th (j=1, 2, . . . , M) optical compensation layer from a first surface of the first optical compensation plate is substantially parallel to the direction of the optic axis of an (M-j+l)-th liquid crystal layer from the first optical compensation plate of the liquid crystal display panel at the time of voltage application, and the direction of the optic axis of an i-th (i=1, 2, . . . , N) optical compensation layer from a third surface of the second optical compensation plate is substantially parallel to the direction of the optic axis of an (M+N-i+l)-th liquid crystal layer from the first optical compensation plate of the liquid crystal display panel at the time of voltage application.
