摘要：
The present invention provides a liquid crystal display device that requires a reduced power consumption, which shows improved response speed and improved viewing angle properties, and that can give high-quality image display at low power consumption, and the liquid crystal display device of the present invention comprises a bend orientation mode liquid crystal cell using a low-temperature polysilicon TFT; and two polarizing plates disposed on both sides of the liquid crystal cell respectively, wherein at least one of the two polarizing plates is an elliptically polarizing plate comprising: a transparent protective layer; a polarizing layer; a transparent support; and an optically anisotropic layer comprising a discotic compound, in this order from outside of the liquid crystal cell, an inclination angle between the disc plane of the discotic compound and the transparent support plane is within a range of 25 to 35 degrees on the average, and the optically anisotropic layer has a Re1 retardation value measured in front of the face of 25 to 50 nm.
