Abstract: A method for fabricating a liquid crystal display device having a TFT substrate in which an alignment film is formed over a pixel including a pixel electrode and a TFT, an opposing substrate which faces the TFT substrate, and liquid crystals sandwiched between the TFT substrate and the opposing substrate, the alignment film on the TFT substrate including a first and a second alignment film. The method includes depositing a mixture liquid of polyamide acid ester, 80 percent or more of which is polyamide acid ester including cyclobutane, and polyamide acid not including cyclobutane onto the TFT substrate and the opposing substrate, and after drying and firing the TFT substrate and the opposing substrate to harden the alignment film, irradiating the alignment film with ultraviolet light for photo-alignment of the alignment film and, thereafter, heating the TFT substrate and the opposing substrate, thereby forming the alignment film.
