An optical writing is demonstrated in homogeneous Liquid crystal (LC) cells using poly (vinyl cinnamate) (PVCi) and rubbed PVA films. The PVCi substrate side of the LC cell is irradiated by the linearly polarized UV light with and without the applied voltage. The change of azimuthal direction of LC alignment is observed when the voltage is applied or not. Moreover, it is clarified that the pretilt angle is generated by the UV irradiation under the applied voltage. These results show that it is possible to control the LC alignment in the azimuthal and polar direction after the LC cells was fabricated.
