Abstract:
A liquid crystal display device, comprising:a pair of polarizing plates; a liquid crystal panel interposed between the pair of polarizing plates, the liquid crystal panel including a liquid crystal layer having liquid crystal molecules, the liquid crystal layer including a pair of regions corresponding to each of pixels, alignment directions of the liquid crystal molecules in the pair of regions being different by about 180 degrees from each other, the liquid crystal panel having a first slow axis; a first phase plate provided between the liquid crystal panel and one of the polarizing plates, the first phase plate having a second slow axis which is horizontal to a surface thereof and substantially perpendicular to the first slow axis of the liquid crystal panel; and a second phase plate provided between the liquid crystal panel and the one of the polarizing plates, the second phase plate having a third slow axis which is substantially perpendicular to both of the first slow axis of the liquid crystal panel and the second slow axis of the first phase plate, wherein the liquid crystal material has a dependency of birefringence anisotropy (&Dgr;n) from 20Â° C. to 60Â° C. ([&Dgr;n(20Â° C.)âˆ’&Dgr;n(60Â° C.)]/40) of 0.00026 or less.
