In the domain-divided TN mode for a wide-viewing-angle LCD, the LC directors are arranged in the splayed TN configuration by mismatching the pretilt directions on both substrates. For this mismatched pretilt alignment, the splayed TN configuration and the reversely-twisted TN configuration are possible. It is shown that the reversely-twisted TN is more stable than the splayed TN in the high voltage range. The splayed TN stability proved to be evaluated by the balanced voltage, defined as voltage at which LC bulk energy becomes equal for two configurations in a simulation or voltage at which the boundary between two configurations is fixed in an experiment. Narrow twist angle, short chiral pitch and low pretilt angles raise the balanced voltage, i.e., stabilize the splayed TN configuration.
