摘要：
We have investigated the control of the pretilt angle and its direction appearing in the tilted homeotropic alignment of nematic liquid crystals oriented on polyimide films that are irradiated with an unpolarized obliquely incident UV light. As a result, it is shown that the pretilt angle is well controlled and its value is shown to be determined by the irradiation energy where the direction of pretilt is governed by the temperature of polyimide films during the course of UV irradiation.
