Abstract

The present invention relates to photo-alignment layers from polyamic acid with a photoreactive aromatic side group. More specifically, the present invention relates to novel polyamic acid photo-alignment layers prepared by the solution polymerization of acid dianhydrides which comprises alicyclic acid dianhydrides at certain ratio or more and aromatic diamines which comprises aromatic diamines with a photoreactive aromatic side group at certain ratio or more and the preparation method thereof, and the preparation method of aromatic diamines with novel aromatic side group. Said polyamic acid photo-alignment layers provide excellent heat- resistance, surface hardness, transparency and liquid crystal alignment property for polarized UV light.
