An in-plane switching mode liquid crystal display having at least two optically anisotropic substance sheets and a liquid crystal cell between a pair of polarizers consisting of a light incident side polarizer and a light emission side polarizer, which have light transmission axes substantially perpendicular to each other. The liquid crystal display satisfies the formula:
(£ n xi + £ n yi ) /2 ‰¦ £ n zi wherein £ is the total of i = 1 to k where k is the number of the anisotropic sheets, n xi and n yi are in-plane principal refractive indexes of an i-th anisotropic, provided that n xi > n yi , and n zi is a principal refractive index in thickness direction; and a multilayered optical body (A) consisting of the k anisotropic sheets and the liquid crystal cell satisfies the formula: 0.90 < R 40 /R 0 < 1.10 wherein R 0 is a retardation when light with wavelength of 550 nm impinges vertically, and R 40 is a retardation when light having a wavelength of 550 nm impinges at an inclination angle of 40° from the normal to the direction of the principal axis.
