摘要:
Provided are a liquid crystal panel and a liquid crystal display apparatus with a high contrast ratio in an oblique direction, less light leakage, a small color shift in an oblique direction, and extremely small thickness. The liquid crystal panel of the present invention includes a liquid crystal cell, a first polarizer arranged on one side of the liquid crystal cell, an optical element (A), an optical element (B), and a second polarizer arranged on the other side of the liquid crystal cell. The optical element (A) exhibits a refractive index ellipsoid of nx>nz>ny, is formed of a specific polycyclic compound, and has an Nz coefficient of 0.05 to 0.45. The optical element (B) exhibits a refractive index ellipsoid of nx>nz>ny and has an Nz coefficient of 0.55 to 0.95.
