摘要： Provided are a liquid crystal composition, a liquid crystal film, a method for preparing the liquid crystal film, and a display device. According to an illustrative liquid crystal composition of the present application, the liquid crystal composition may be uniformly coated at normal temperature without any need for adding heat, and thus the process is economical in terms of process, thereby allowing an equipment to be simply manipulated. Also, according to an illustrative liquid crystal composition, an appropriate fluidity may be secured even after a solvent for the liquid crystal composition is dried, and thus uniform alignment may be induced. Furthermore, according to an illustrative liquid crystal composition, uniform liquid crystal alignment may be performed even while liquid crystals are aligned in a wide area.
