Abstract:
A liquid crystal display device comprising a liquid crystal panel having a cell 15 and polarizing plates 11, 12; wherein a liquid crystal molecule is rotated in parallel to the cell 15, the polarizing plate 12 has a multiple polarizer layer formed thereon, the multiple player having a first polarizer layer having a higher polarization degree with respect to a light from a forward direction than a polarization degree with respect to a light from a oblique direction and a second polarizer layer having a higher polarization degree with respect to a light from a oblique direction than a polarization degree with respect to a light from a forward direction, and an average elastic constant of a splay elastic constant K1, a twist elastic constant K2, and a bend elastic constant K3 of liquid crystal material is equal to 10×10−12 N or larger and satisfies a relationship of K1/K2
