发明名称 LIQUID CRYSTAL DISPLAY DEVICE
摘要 <p>A liquid crystal display device includes a liquid crystal panel (2) disposed between two linear polarization plates (1, 3) and a triacetyl cellulose film having biaxial optical anisotropy (4), the triacetyl cellulose film having biaxial optical anisotropy (4) (i) being disposed further from the screen front side than a front polarization plate, which is one of the two linear polarization plates (1, 3), 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.</p>
