The present invention relates to a norbornene monomer, a polynorbornene derivative, a liquid crystal alignment film including the same, and a liquid crystal display device including the same. More particularly, the present invention relates to a norbornene monomer, a polynorbornene derivative, a liquid crystal alignment film including the same, and a liquid crystal display device including the same, which have an alignment property by photoreaction, excellent thermal stability and photoreactivity, the increased photo-reaction rate and reliability of the alignment film, thereby showing high manufacturing process efficiency.

The present invention relates to a novel cyclic olefin compound, a polymer including the cyclic olefin compound, a liquid crystal alignment film including the polymer, and a liquid crystal display device including the liquid crystal alignment film. Since the polymer includes the cyclic olefin compound as a main chain, the thermal stability is excellent and the photoreactive speed is high. Accordingly, the production time can be reduced, the production cost can be reduced, and the anchoring force of the liquid crystal can be increased because the alignment property is stabilized due to the curing.
