Abstract
Exposure of rubbing polyimide (PI) film to depolarized ultraviolet (UV) lig ht suppressed the effective anchoring energy of liquid crystal (LC) with al igning surface. Polarized light changed the orientational distribution of P I molecules obtained by rubbing by changing both the anchoring energy and e asy axis direction. These results show that ultraviolet exposure can be eff ectively used to control anchoring parameters.
