Provided is a liquid crystal composition capable of forming an optically anisotropic layer, and method thereof, in which a variation in a twisted angle of liquid crystal compound in an in-plane direction is suppressed an optical film, and a circularly polarizing plate for an organic EL display. The liquid crystal composition contains a liquid crystal, optically active compound A which is a photosensitive optically active compound whose helical twisting power changes upon irradiation with light and has a molar absorption coefficient of 5,000 M
