The present invention provides: an ink composition capable of forming a liquid crystal layer even on a base material with no alignment treatment applied, capable of obtaining a high contrast display when viewed from the front side, having a low Haze, capable of satisfying the physical properties required for the optical characteristics of an optical film, having a high production yield, and efficient and stable in terms of the industrial productivity; and an optical film, a polarizing film and a liquid crystal display produced using the ink composition. The liquid crystal layer forming ink composition comprises a liquid crystalline molecular material, an organic solvent for dissolving or dispersing the molecular material, and an alcohols solvent. By applying the ink composition on a base material 2, drying, and aligning the liquid crystal molecule material, an optical film 1 with a liquid crystal layer 3 formed can be obtained. Since the alcohols solvent is contained in the liquid crystal composition, the liquid crystalline molecular material is in a state horizontally aligned on the base material, and the optical film can have a high transparency.
