位相差膜によるTN-LCDの広視野角化

抄録

To obtain the viewing angle characteristics of a TN-LCD with optical compensators, the Jones matrix method was applied to oblique directions. The method was employed to optimize the optical compensators, taking contrast and grayscale capability into account. In this paper, an optical compensator comprising two layers is proposed. One layer has negative birefringence and an oblique optical axis, and the other has negative birefringence and a vertical optical axis. As the result of the optimization, the TN-LCD sandwitched by these compensators exhibits excellent viewing angle characteristics.
