An optical compensation film having: a retardation value Re in a film plane of the optical compensation film; and a retardation value Rth in a thickness direction of the optical compensation film, the retardation value Re and Rth being reduced by an elongation, satisfying the formulae (1) and (2) without the elongation, and satisfying the formulae (3) to (6) after the elongation: <?in-line-formulae description="In-line Formulae" end="lead"?>Re=0 to 30 nm (1) <?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>Rth=-50 to 50 nm (2) <?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>Re(n)=-500 to 0 nm (3) <?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>Rth(n)=-800 to 0 nm (4) <?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>Re(n)-Re(0)<0 (5) <?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>Rth(n)-Rth(0)<0 (6) <?in-line-formulae description="In-line Formulae" end="tail"?>
