<title>Wide-viewing-angle LCD controlled by a lateral electric field</title>

Abstract

With the aim of developing a wide viewing angle Liquid Crystal Display (LCD), we are trying to apply In-Plane Switching (JPS) mode, in which liquid crystal molecules are switched by a lateral electric field, to TFT-LCD. We have studied the detailed relationship between the electro-optical properties and the various panel conditions. From these results, we specified the panel conditions, such as +10.4 dielectric anisotoropy of liquid crystal material, 3.5 tm panel gap and 8 .tm electrode spacing, to fabricate the IPS mode Tfl panel.We have achieved the IPS mode TFT color panel that possessed not only wide viewing angle characteristics over 80 °with no reversed image but also a fast response time 50ms , a low driving voltage compatible with ordinary Twisted Nematic (IN) mode TFT panel and a fine white balance,(x,y)=(032,034).
