摘要： The present invention provides a semi-transmissive or reflective liquid crystal display device in which gray scale inversion is suppressed by appropriately adjusting its voltage-reflection luminance characteristics. The liquid crystal display device of the present invention is a liquid crystal display device including: a pair of substrates; and a liquid crystal layer interposed between the pair of substrates, wherein the liquid crystal display device includes a transmission region and a reflection region, the reflection region includes a first section and a second section, a thickness of the liquid crystal layer in the first section is larger than half of but equal to or smaller than a thickness of the liquid crystal layer in the transmission region, and a thickness of the liquid crystal layer in the second section is larger than the thickness of the liquid crystal layer in the transmission region.

摘要： 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.
