    摘要： A phase difference plate capable of eliminating contrast changes due to viewing angle changes of display image, coloring phenomenon of display screen, and black and white reversal phenomenon, and a liquid crystal display device capable of displaying images of high quality are presented. A phase difference plate is a drawn and elongated material possessing optical anisotropy such as high polymer compound formed in a flat plate form, and the direction of the minimum principal refractive index na of the three principal refractive indices na, nb, nc of the index ellipsoid is parallel to the y-axis direction, and the direction of the principal refractive index nb is inclined to the normal direction of the surface.
