Composition for liquid crystal aligning, liquid crystal aligning layer prepared from the same, and liquid crystal display comprising the same
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.
