Multi-layered liquid crystal panel with twisted nematic liquid crystal material having polarizers displaced for sharp-rising characteristic |
摘要 |
A multi-layered liquid crystal display device is disclosed, which includes a stack of liquid crystal layers in which the longitudinal axes of the liquid crystal molecules extend spirally, the liquid crystal layers being disposed in parallel with the spiral axes. A voltage supply is provided for supplying a voltage to at least a portion of the liquid crystal layers for conversion of the molecular alignment. Also provided is a pair of polarizers for making visible the conversion of the molecular alignment. More particularly, the polarization direction of the polarizers or direction normal to the polarization direction is deflected within the range of 3 DEG to 15 DEG with respect to the longitudinal direction of the liquid crystal molecules in a sense to reduce the spiral angle of the liquid crystal layers and the deflection angle is substantially in alignment with the longitudinal direction of the liquid crystal molecules.
