    摘要: The present invention provides a composition for forming a liquid crystal alignment film, which comprises a photoreactive polymer including a multicyclic compound having a photoreactive group on a main chain thereof. The present invention also provides a liquid crystal alignment film produced using the composition, and a liquid crystal display including the liquid crystal alignment film. The photoreactive polymer including the multicyclic compound on the main chain thereof has a high glass transition temperature, thus thermal stability is excellent. Since lattice vacancy is relatively large, the photoreactive group is capable of moving relatively freely in the main chain of the polymer, thus it is possible to improve a slow photoreaction rate, which is considered a disadvantage of a conventional polymer material.

    摘要: A composition for forming column spacers is provided. The composition comprises a radical polymerization inhibitor. The use of the composition enables simultaneous formation of a saturated pattern and a semi-transmissive pattern as column spacer patterns having different shapes, whose difference in thickness is controllable as desired although the sensitivity is slightly reduced, through a slit or semi-transmissive mask by varying the kind and amount of the radical polymerization inhibitor. Further provided are column spacers formed using composition and a liquid crystal display using the column spacers.

    摘要: A novel photoactive compound is provided. The photoactive compound has a structure represented by Formula 1: wherein R1, R2, R3, A, X, Y, n and m are as defined in the specification. The photoactive compound efficiently absorbs UV light. Accordingly, the photoactive compound has an improved ability to generate radicals and is efficiently photopolymerized with unsaturated bonds. Further provided is a photosensitive resin composition comprising the photoactive compound. The photosensitive resin composition has good sensitivity because it efficiently absorbs UV light. In addition, the photosensitive resin composition has excellent characteristics in terms of residual film ratio, mechanical strength and resistance to heat, chemicals and development. Therefore, the photosensitive resin composition is advantageously used in curing materials for column spacers, overcoats and passivation films of liquid crystal display devices. In addition, the photosensitive resin composition has excellent thermal processing characteristics.
