Abstract

We have investigated the electro-optical characteristics of amorphous (a)-twisted nematic (TN)-liquid crystal display (LCD) on two kinds of the polyimide (PI) surfaces. We obtained that the LC aligning capabilities is strongly dependent on molecular structure of the polymer. Also, we found that the domain size of a-TN-LCD on PI surface having CONH moiety is small compared to a-TN-LCD on PI surfaces with side chain. Also, we observed that the response time of a-TN-LCD on PI surfaces having CONH moiety is slow compared to a-TN-LCD on PI surfaces with side chain. It is considered that the response time of a-TN-LCD results from a surface effect between the substrate surface and the LC molecules. Finally, we obtained that the viewing angle of a-TN-LCD increases with decreasing the domain size.
