PURPOSE: A liquid crystal alignment composition is provided to enhance the reactivity of optical reactive group by adding photo activators to norbornene-based polymer having optical reactive groups. CONSTITUTION: A liquid crystal alignment composition includes, based on the total weight of the composition, 50-70 weight% of a norbornene-based polymer with a photo-reactive group represented by chemical formula 1, 1-20 weight% of a photo-activator containing a compound represented by chemical formula 2, 20-40 weight% of (meth)acrylate-based compounds, and 1-15 weight% of photoinitiator. |
