利用线偏振光在光致聚合物聚乙烯肉桂酸酯（PVCi）膜上实现了非线性液晶（NLC）的光取向。阐明了液晶取向的机理，并通过适当组合线性偏振紫外光的垂直和倾斜曝光，得到了具有预倾角的良好的单向液晶取向。这种光对准方法被应用于制造超多畴（SMD）TN-LCD，使四分之一像素的功能，我们证明了反倾斜向错（RTD）的SMD TN-LCD成功地制造使用的光对准方法。
A photo-alignment of nematic liquid crystals (NLC) on a photopolymer film of polyvinyl cinnamate (PVCi) has been achieved by using linearly-polarized UV light. The mechanism of the LC alignment is clarified and good unidirectional LC alignment with pretilt angle is obtained by appropriate combination of normal and oblique exposure of linearly-polarized UV light to the PVCi films. This photo-alignment method is applied to fabricate super-multidomain (SMD) TN-LCDs making a feature of quartered pixels, and we demonstrate that reverse tilt disclination (RTD)-free SMD TN-LCDs is successfully fabricated by using the photo-alignment method.
