The relation between viewing angle characteristics of TN-LCDs and liquid crystal (LC) aligning properties was studied. Three type TN-LCDs with different surface alignments under the retardation condition of 2nd minimum were prepared. Cells of type 1 and 2 are filled with a nematic and a chiral nematic (cell thickness / chiral pitch=0.25) LCs respectively, although both of them are constructed with a pair of rubbed and MOLCA-treated substrates. By choosing the strength of magnetic fields, the LC direction ordering on the substrates treated by MOLCA is controllable. From conoscopic observation of type 1,2 and conventional rubbing TN-LCD, improvement of the viewing angle characteristics could be recognized.
