Abstract
The present invention relates to a photoreactive norbornene polymer comprising a photoreactive norbornene monomer, a process for preparing the same, and an alignment layer using the same. The photoreactive norbornene polymer includes a photoreactive functional group having a halogen, in particular, a fluorine substituent group so that it gives a compositional gradient in the alignment layer to improve an orientation rate, an orientation, and an adhesion property.
