Abstract

A twisted nematic liquid crystal cell with two transparent conductive substrates each of which has two metal terminals was studied. It was found that a circular or elliptical light-transmitting area (bright area) was formed in the, cell window by applying four kinds of voltage signals to each terminal. The light-transmitting area was varied by changing the effective voltage, and the cell behavior was consistent with theoretical results for the voltage distribution in the cell window.
