The present invention relates to a photoreactive copolymer and an alignment layer comprising the photoreactive copolymer, and more particularly, to a photoreactive copolymer comprising a copolymer containing two different types of monomers and an alignment layer comprising the photoreactive copolymer. The photoreactive copolymer of the present invention exhibits excellent liquid crystal alignment and alignment speed, and has a characteristic that its alignment direction can be easily changed according to the polarization direction. In addition, due to excellent solubility in organic solvents, the photoreactive copolymer of the present invention can be applied to various fields such as liquid crystal devices. |
