Patent ID: 8722158

Claim:
A liquid crystal photo-alignment agent comprising: an epoxy compound comprising a compound represented by the following Chemical Formula 2, Chemical Formula 4, or a combination thereof, and a polymer comprising a polyamic acid, a polyimide, or a mixture thereof, wherein, in the above Chemical Formula 2, R 2 to R 6 are independently hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted aryl, or substituted or unsubstituted heteroaryl, and R 7 to R 12 are independently substituents selected from the group consisting of hydrogen, C1 to C20 alkyl, C2 to C20 alkoxyalkyl, C1 to C20 haloalkyl, and an aromatic group, or substituents selected from the group consisting of C1 to C6 alkyl and an alicyclic group, wherein, in the above Chemical Formula 4, R 20 to R 24 are independently hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted aryl, or substituted or unsubstituted heteroaryl, R 25 and R 26 are independently hydrogen, halogen, cyano, or substituted or unsubstituted C1 to C12 alkyl, wherein in R 25 and R 26 , the substituted alkyl is an alkyl substituted with halogen, cyano, or a combination thereof, or is an alkyl comprising one or more non-adjacent CH 2 groups substituted with —O—, —CO—O—, —O—CO—, —CH═CH—, or a combination thereof, and R 27 to R 30 are independently substituents selected from the group consisting of hydrogen, C1 to C20 alkyl, C2 to C20 alkoxyalkyl, C1 to C20 haloalkyl, and an aromatic group, or substituents selected from the group consisting of C1 to C6 alkyl and an alicyclic group.
