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.

Cyclic olefins compounds, polymers comprising the same and liquid crystal alignment films including the polymers

The present invention to a composition for liquid crystal aligning comprising an oligoimide or oligoamic acid, which comprises a thermocurable or photocurable functional group on at least one end of the oligoimide or oligoamic acid backbone, a liquid crystal aligning layer prepared from the same, and a liquid crystal display comprising the same. The composition for liquid crystal aligning according to the present can minimize the generation of the decomposed by-products, which had been generated upon the use of polyimides, by using an oligoimide or oligoamic acid on at least one end of the backbone, instead of the conventional polyimides and has an excellent effect of improvement in alignment property, thermal stability, and image sticking.
