Optical alignment composition, alignment layer formed using the same and LCD having the alignment layer

摘要

An optical alignment composition, an alignment layer formed using the same with an excellent thermal stability, and an LCD having the alignment layer are provided. The optical alignment composition includes a multifunctional cinnamate compound and a cinnamate group containing polymer in a weight ratio of 1:9 to 2:8. Thus, an optical alignment composition and an alignment layer each having excellent thermal stability and alignment property can be obtained while adopting a non-destructive optical alignment method. Accordingly, an LCD with improved performance can be obtained.
