Optical alignment composition, alignment layer formed using the same and LCD having the alignment layer |
摘要 |
An optical alignment composition including a first polymer selected from a cinnamate-series polymer and a coumarin-series polymer, and a second polymer selected from polyimide having a long-chain alkyl group at its side chains and polyimide having an alkyl group at its both ends, an alignment layer formed using the same, and a liquid crystal display having the alignment layer are provided. According to the present invention, the thermal stability of the alignment layer and pretilt angle characteristic of the liquid crystal are improved.
