The polarity effects of dielectric anisotropy on the electro-optical characteristics of a twisted nematic mode driven by a fringe electric field that has wide viewing angle characteristics was the focus of this study. The device used in this study was designed to be a normally black mode between parallel polarizers. The perfect polarization conversion of the incident light, which passed through a polarizer, was achieved when it passed through a twisted Liquid Crystal (LC) layer. When an electric field was applied, the LC molecules with a positive (or negative) dielectric anisotropy rotated parallel (or perpendicular) to the horizontal component of a fringe electric field as the transmittance increased. According to the calculated results, an enhanced transmittance of the Fringe Field-Twisted Nematic (FF-TN) mode with a positive dielectric anisotropy of + 8.2 was be obtained.

介电各向异性对具有宽视角特性的边缘电场驱动的扭曲向列模式的电光特性的极性影响是本研究的重点。本研究中使用的设备被设计为平行偏振器之间的常黑模式。通过偏振器的入射光通过扭曲液晶（LC）层时，可以实现完美的偏振转换。当施加电场时，随着透射率的增加，具有正（或负）介电各向异性的LC分子平行于（或垂直）于边缘电场的水平分量旋转。根据计算结果，
