摘要A new and simple electric charge interaction mechanism has been proposed to explain the behaviour of the tilt angle of liquid crystals by rubbing. The mechanism of the molecular alignment is elucidated based on the effect of a static electric charge on a substrate surface treated by rubbing. An electric field which is dependent on the topology of a substrate surface allows a planar orientation of molecules with positive dielectric anisotropy. With increasing rubbing strength, the tilt angle varies slowly. The director of molecules with negative dielectric anisotropy is uniform and has a tilt angle determined by the molecular permanent dipole direction. The air-liquid crystal interface case is also considered. This model enables us to give a unified picture of the molecular alignment mechanism.
