A plasma-beam-irradiated PI film has been used in flexible liquid crystal display manufacturing. The beam had energy of 450 eV and incident angle of 70° with respect to normal flexible indium-zinc-oxide coated substrate. The pretilt angle and anchoring energy of LCs on plasma aligned PI surface were almost identical to those on rubbing aligned PI surface. However, the optical performance of plasma aligned cell was superior to the rubbing cell under various bending conditions. Furthermore, such non-contact alignment technology is suitable for large area and roll-to-roll fabrication of flexible LC films.
