本文研究了以三乙酰纤维素（TAC）为基片，以二苯并咪唑化合物为补偿膜的扭曲液晶（TN-LCD）的补偿机理。整个补偿膜的光学特性被确定为单轴负双折射，其光轴从法线方向倾斜，该补偿膜具有在TAC衬底上的混合取向的掺杂化合物层。我们确定TN-LCD的观看特性不是由显示层的光学参数决定的，而是由显示层和TAC基板作为整体的组合决定的。
The compensatory mechanism of twisted nematic liquid crystals (TN-LCDs) with compensation films composed of discotic compounds and triacetylcellulose (TAC) substrate has been investigated. The optical characteristics of the entire compensation film which has a hybrid aligned discotic compound layer on a TAC substrate were identified as uniaxial negative birefringence whose optical axis was inclined from the normal direction. We determined that the viewing characteristics of TN-LCDs were governed by the optical parameters not of the discotic layer but of a combination of the discotic layer and the TAC substrate as a whole.
