Abstract
Disclosed are an alignment layer and a liquid crystal display having the same. The alignment layer comprises a polyimide compound having an azo group and exhibiting optical alignment characteristics and a discotic liquid crystal compound exhibiting optical anisotropy. The liquid crystal display comprises first and second substrates facing each other, liquid crystal aligned between the first and second substrates, and an alignment layer formed on at least one surface of the first and second substrates. The alignment layer is adjacent to the liquid crystal and has optical alignment characteristics and optical anisotropy.
