Patent ID: 7901605

Claim:
A method of making a liquid crystal display device, comprising: providing first and second substrates; forming a first alignment layer on the first substrate, wherein the first alignment layer includes where spacer S is OC h H 2h , where h=1˜5, where m=10˜10,000, where the functional group R includes at least one of a group consisting of photo-sensitive constituents and non-photo-sensitive constituents; and forming a liquid crystal layer between the first and second substrates, wherein the non-photo-sensitive constituents include a material selected from the group consisting of H, OC n H 2n , OC n H 2n+1 , COC n H 2n+1 , C n H 2n OH, OC n H 2n OH, OCOC n H 2n+1 , OC n H 2n+1−x F x , OC n H 2n−(x−1) F (x−1) , C n H 2n−(x−1) F (x−1) OH, OC n H 2n−(x−1) F x−1 OH, COC n H 2n+1−x F x , OCOC n H 2n+1−x F x , where n=1˜10 and x=1˜2n+1, and any combination thereof, wherein the photo-sensitive constituents include a cinnamoyl derivative, wherein the cinnamoyl derivative is where X1 and X2 are each selected from the group consisting of hydrogen, fluorine, chlorine, CN, NO 2 , CH 3 , OCH 3 , CF 3 , OCF 3 ; where k is 0 to 1; where Y is selected from the group consisting of hydrogen, fluorine, chlorine, cyano, NO 2 , CF 3 , OCF 3 ,C n H 2n+1 , OC n H 2n+1 , C n H 2n+1−x F x , OC n H 2n+1−x F x , where n=1˜10 and x=1˜2n+1.
