Abstract:
A liquid crystal panel according to the present invention includes a backlight portion emitting light having a brightness distribution in a horizontally oblong oval shape assuming that a longitudinal direction of a panel is a horizontal direction; a first polarizer; a liquid crystal cell; an optical compensation layer having a refractive index profile of nx>ny>nz; and a second polarizer, in this order from a backlight side. According to the present invention, a liquid crystal panel having remarkably excellent contrast in an oblique direction, small light leakage in a black display and a small color shift is provided.
