Abstract:	This investigation demonstrates the feasibility of re-aligning the assembled liquid crystal cells based on rubbed substrates with photoalignment treatment. A pre-exposure process is proposed to achieve the photo-reorientation effectively. This study shows that the fine-tuning on the LC alignment after a cell is assembled by adjusting UV irradiation conditions can be obtained easily.
