Abstract
An object of the present invention is to provide a phase difference film having excellent alignment without the need for alignment treatment on a support, a method for manufacturing a phase difference film, a polarizing plate, and a liquid crystal display device. The phase difference film of the present invention includes a support, and a liquid crystal layer formed of a liquid crystal composition containing a liquid crystalline compound so as to be in contact with the support, in which a surface energy of a surface of the support on which the liquid crystal layer is formed is 45 mN/m or more and a non-polar dispersion force component included in the surface energy is 45 mN/m or more, the liquid crystalline compound is immobilized in an aligned state, and a contrast is more than 10000.
