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.
