The present invention can provide an optical film suitable for a liquid crystal display apparatus providing colorless neutral display in all azimuth angle directions, a liquid crystal panel employing the optical film, and a liquid crystal display apparatus employing the liquid crystal panel. The optical film of the present invention includes a first transparent protective film, a polarizer, a second transparent protective film, and a birefringent layer having a relationship of nx>ny=nz and positive uniaxial property in the stated order, in which the second transparent protective film has a thickness direction retardation (Rth) represented by the formula (1) of 10 nm or less. <?in-line-formulae description="In-line Formulae" end="lead"?>Rth=(nx-nz)xd (1) <?in-line-formulae description="In-line Formulae" end="tail"?>
