초록
We study pretilt angle control of liquid crystal from homogeneous to homeotropic using phase separation techniques of photocurable prepolymer by UV irradiation. Pretilt angle was controlled by changing the weight ratio of LC/photocurable prepolymer in homogeneous polyimide (PI) coated LC cell. Homogeneous alignment was observed in LC/photocurable prepolymer mixture of weight ratio of 99.9:0.1 after UV irradiation for 20 minutes. Tilted alignment was observed in weight ratio of 99.8:0.2. Finally homeotropic alignment was observed in weight ratio of over 99.7:0.3. © 2012 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).
