    摘要： The present invention relates to a photoreactive polymer that comprises a multi-cyclic compound in a main chain, and a polymerization method thereof. Since the photoreactive polymer according to the present invention comprises a multi-cyclic compound having a high glass transition temperature as a main chain, the thermal stability is excellent, and since the mobility of the main chain is relatively high as compared to that of an additional polymer, a photoreactive group can be freely moved in the main chain of the polymer. Accordingly, it is possible to overcome a slow photoreactive rate that is considered a disadvantage of a polymer material used to prepare an alignment film for known liquid crystal display devices.

    摘要： The present invention relates to a composition for liquid crystal alignment layer, a preparation method of liquid crystal alignment layer using the same, and an optical film comprising the liquid crystal alignment layer. More particularly, the composition for liquid crystal alignment layer according to the present invention includes crosslinkable functional monomers as well as a photoreactive polymer, thereby improving thermal stability and durability of the liquid crystal alignment layer that is prepared by using the composition for liquid crystal alignment layer. In addition, when the liquid crystal alignment layer is used to produce an optical film, adhesive strength between substrate and liquid crystal alignment layer and between liquid crystal alignment layer and liquid crystal film can be improved.
