摘　　要：在玻璃衬底上制备浮雕型全息光栅作为液晶显示器件取向层,分析了液晶层厚度对液晶分子在光栅取向层上排列的影响。发现液晶层厚度约为8μm时,液晶分子是沿光栅沟槽方向一致排列,其显微织构均匀,各点光强均匀一致,两个相同光强的状态周期为90,°周期性的微沟槽是促使液晶分子取向一致的主要原因。Holographic surface relief gratings were employed as the orientation layer for liquid crystal display. The influence of liquid crystal thickness on the alignment of liquid crystal on gratings are analyzed. When the thickness of the liquid crystal layer is about 8 μm, uniform texture is formed and the liquid crystal molecules align along the grooves of the gratings, the transmitted light intensity changes periodically as the gratings rotated 90°. Period grating is the main reason for liquid crystal uniform alignment.
