摘要: An object of the present invention is to provide an optical film capable contributing reduction in thickness, preventing uneven heating, and favorably light leak black display, image display apparatus using such film. includes a polarizer, first compensation layer having refractive index profile nx>ny=nz, second nx>ny>nz stated order. In film, angle formed between absorption axis polarizer slow +17° +27° or −17° −27°, +85° +95°, Nz coefficient 1.2≦Nz≦2.
