    • A liquid crystal shutter is provided comprising at least two liquid crystal cells and at least three polarizers. Each of the liquid crystal cells contains a plurality of layers between two substrates and is disposed between two adjacent polarizers. The adjacent two liquid crystal cells have substantially equal absolute values and opposite directions of twist angles. The liquid crystal shutter of the invention substantially increases the viewing angle and the contrast ratio at large viewing angles, provides a symmetrical dependence of the contrast ratio on the viewing angle, and decreases the switching time as well as the driving voltages. The shutter provides substantially improved angular characteristics, high contrast ratio, good transparency in the light state, and a fast switching time.
    • 提供了包括至少两个液晶单元和至少三个偏振器的液晶快门。 每个液晶单元在两个基板之间包含多个层,并且设置在两个相邻的偏振器之间。 相邻的两个液晶单元具有基本相等的绝对值和相反的扭转方向。 本发明的液晶快门在大视角下显着增加了视角和对比度,提供了对比度对视角的对称关系,并且减小了切换时间以及驱动电压。 快门提供显着改善的角度特性,高对比度,光状态下的良好透明度和快速切换时间。
