UNUSUAL VOLTAGE-HOLDING RATIO CHARACTERISTICS USING INPLANE SWITCHINGOF NEMATIC LIQUID-CRYSTALS

Unusual characteristics of the voltage-holding ratio were found when u sing in-plane switching of homogeneously oriented nematic liquid cryst als. Even when employing liquid crystals with much lower resistivity t han is applicable to the conventional active matrix driving technique, voltage-holding ratio characteristics were higher than those in conve ntional electric fields applied along the direction perpendicular to t he substrate plane. The unusual holding ratio characteristics were att ributed to the electric held direction being approximately parallel to the substrate plane.
