Nanop articles-doped guest-host liquid crystal displays

The technique, nanoparticles-induced vertical alignment (NIVA), was applied to fabricate a guest-host liquid crystal display (GH-LCD) without conventional alignment layers. The GH-LCD produced by NIVA exhibited a high reflectance of similar to 59% in the voltage-off state and a low threshold voltage of similar to 2.1 V-rms. NIVA is very suitable to be applied for fabricating a plastic LCD requiring a low temperature process, and a flexible timepiece by using NIVA was demonstrated. (c) 2008 Optical Society of America
