E. OCB mode LCD elements . Then,we added bi-functional powder and LC E7 in the bulk copolymer of Poly Acrylic Acid and EOPO,then poured the LC solution,and exposed it with 5V voltages under ultraviolet radiation. Finally,we observed the changing phenomena of the planar display of OCB cell with additional external voltage under polarized microscopy . It can be observe obviously the polymer wall in OCB cell when NO.4 LC solution having concentration of 3％ wt . At the same time,the polymer which didn't sheltered by mask will polymerize,then,lead LC into high inclined angle alignment. And it formed discontinuous structure along mask affected LC which surrounded the wall. The results measured by photoelectric instruments showed the discontinuous structure not only keeps the inner LC structure at twist mode,but also promotes the originated respond-velocity of OCB.
