PCa03 方位角アンカリングエネルギーがTNセルの光学特性に及ぼす影響(2)

The anchoring energy measurement (polar and azimuth) has been proposed in order to quantity the alignment forces at the interfaces between a liquid crystal layer and alignment layers. In this report, measurement is focused on the azimuth anchoring energy. In order to observe how the switching characteristics of the twisted-nematic(TN)-cells change, we measured the azimuth anchoring energy of the TN-cells which have different rubbing strength. We confirmed that the switching characteristics of TN-cells change by changing the azimuth anchoring energy. We input the azimuth anchoring energy obtained by the experiment to a commercial LCD simulation software to obtain the switching characteristics by calculation, and then studied correlation between such switching characteristics and our test results. We confirmed that there is a good correlation between the calculated results and the experimental results.
