Effects of the surface LC alignment order on electro-optical characteristics of twisted nematic LCDs were studied, experimentally. Surface aligning order was controlled by changing magnetic field strength in MOLCA (Magnetically Oriented Liquid Crystalline Adsorbate) treatment. By deteriorating the order, the area of contrast ratio above 10:1 and without any gray scale inversion shifted vertically downward, compared with conventional rubbing TN-LCD. The transitions in chromaticity diagram with changing of viewing angle at 3 volts rms were greatly suppressed. Moreover, response time in decay was shortened.
