  • Patent number: 7655284
    Abstract: Disclosed is a multi-functional monomer including a heat-curable functional group as well as a typical photoreactive group. In the multi-functional monomer, the photoreactive group is not chained to a main chain of a polymer. Thus, since it is possible to perform desirable alignment treatment even though polarized UV is radiated for a short time, the production time and the production cost are reduced and alignment regulating force of liquid crystals is increased, thereby increasing a dichroic ratio.

  • Patent number: 7556910
    Abstract: The present invention relates to a photosensitive composition comprising a triazine-based photoactive compound containing oxime ester. The photosensitive composition according to the present invention has good sensitivity, retention rate, mechanical strength, heat resistance, chemical resistance and developing durability since it contains, as photopolymerization initiator, a compound having an oxime ester group and a triazine group in one molecule and thus effectively absorbs UV radiation. Therefore, the photosensitive composition according to the present invention is advantageous not only in curing of materials for color filters, resin black matrixes, column spacers, overcoats and passivation films of liquid crystal displays, but also in high temperature process characteristics.

  • Patent number: 7541073
    Abstract: 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.
