A liquid crystal display device includes a liquid crystal panel () disposed between two linear polarization plates () and a triacetyl cellulose film having biaxial optical anisotropy (), the triacetyl cellulose film having biaxial optical anisotropy () (i) being disposed further from the screen front side than a front polarization plate, which is one of the two linear polarization plates (), and (ii) having a planar retardation comprised in a range from 40 nm to 100 nm. Accordingly, it is possible to provide a liquid crystal display device allowing an observer to perceive, through polarized sunglasses and with a high display quality, an image on a screen not only from a frontal viewpoint but also if an azimuth angle and a polar angle at which viewpoints are set are shifted from the frontal viewpoint.
