我们提出了一种使用表面浮雕光栅制造垂直排列多域液晶显示器（LCD）的新方法。通过光掩模照射紫外光，在涂覆在玻璃基板上的光敏聚合物中产生表面浮雕光栅的线性阵列。 LCD单元由两个光栅表面组装而成，其光栅矢量彼此正交。在这种配置中，向列分子通过光栅表面的扭曲电场重新定向，形成四个不同的域。该电池在关闭状态下显示出良好的消光性，在开启状态下显示出宽视角特性。
We propose a new method of fabricating a vertically aligned multidomain liquid crystal display (LCD) using surface relief gratings. A linear array of surface relief gratings is produced in the photosensitive polymer coated on glass substrates by the illumination of the UV light through a photomask. The LCD cell is assembled with two grating surfaces in such way that their grating vectors are orthogonal to each other. In this configuration, the nematic molecules are reoriented by a distorted electric field at the grating surfaces to make four different domains. The cell shows good extinction in the off-state and the wideviewing property in the on-state.
