The present invention relates to a method for producing a liquid crystal alignment film, a liquid crystal alignment film, and a liquid crystal display device including the liquid crystal alignment film. More specifically, according to the above preparation method, after the liquid crystal alignment agent is applied and dried on the substrate, the high-temperature heat treatment process is omitted, and the light is immediately irradiated for the alignment treatment, followed by heat treatment to be cured, thereby preparing a liquid crystal alignment film, and Therefore, the method for preparing a liquid crystal alignment film having improved alignment characteristics and stability can reduce the light irradiation energy required in the process and omit the high-temperature heat treatment process before the light irradiation, and therefore, the method is simple. A liquid crystal alignment film and a liquid crystal display device including the same are provided. |
