Abstract

This paper presents a dual-view (DV) liquid crystal display (LCD) fabricated with a twisted nematic (TN) cell that has patterned electrodes on its substrates. The TN DV LCD effectively inhibits the bright state light leakage in the un-intended viewing direction, improving the contrast ratio of the DV LCD when the right and the left subpixels of the DV LCD are addressed simultaneously. In the preferred viewing direction, the TN DV LCD has a high contrast ratio of ~ 140:1.
