PROBLEM TO BE SOLVED: To provide a liquid crystal aligning film having high voltage retention and good printability on an organic film such as a protective film, and a transverse electric field system liquid crystal display device having the liquid crystal aligning film. SOLUTION: The liquid crystal aligning agent contains a polymer having a polyamic acid repeating unit and a repeating unit of imidated polyamic acid, a compound having four epoxy groups in a molecule and a silane coupling agent. The liquid crystal display device has the liquid crystal aligning film formed of the liquid crystal aligning agent. COPYRIGHT: (C)2007,JPO&INPIT
