Liquid crystal device and display
摘要:
A surface mode liquid crystal device, for example of the pi-cell type, comprises a layer nematic liquid crystal (10) disposed between alignment layers (4,9) and an electrode arrangement (3,8). The nematic liquid crystal has viscosity coefficients &eegr;1, &eegr;2 and &ggr;1, such that (&eegr;1-&eegr;2)/&ggr;1≧1.15 or (&eegr;1-&eegr;2)/&ggr;1≦0.9.
