The characteristics of the response time and the viewing angle on twisted nematic(TN)-liquid crystal display(LCD) and amorphous (a)-TN-LCD without rubbing were investigated. To measure the Tansmission-Voltage, response time, and viewing angle characteristics, we prepared three kinds of LC cells and then studied the surface liquid crystal alignment effect. It was found that the response time on a-TN-LCD was fast compared to the TN-LCD, and the weak anchoring strength was attributed to the fast response time on a-TN-LCD. Also, we obtained the wide viewing angle characteristics on-a-LCD. We suggest that the liquid crystal alignment effect on LCD device is very important for electro-optical characteristics.
