Abstract
A liquid crystal display device comprising a liquid crystal panel having a celland polarizing plates; wherein a liquid crystal molecule is rotated in parallel to the cell, the polarizing platehas 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 K, a twist elastic constant K, and a bend elastic constant Kof liquid crystal material is equal to 10×10N or larger and satisfies a relationship of K/K<=1.5.
