PROBLEM TO BE SOLVED: To provide an optical compensation film contributing to the improvement of viewing angle characteristics of a liquid crystal display device, particularly an IPS liquid crystal display device, and a composition useful for the production of the optical compensation film. A liquid crystal composition comprising at least one onium salt, at least one rod-like liquid crystal compound, and at least one additive that promotes vertical alignment at the air interface of the rod-like liquid crystal compound, and the liquid crystal composition An optical compensation film having an optically anisotropic layer formed.
