Zigzag Electrodes for Suppressing the Color Shift of Kerr Effect-Based Liquid Crystal Displays

The electro-optic properties of Kerr effect based liquid crystal display (LCD) with zigzag electrode structure are studied using a three-dimensional simulator. The optimal bending angle of the zigzag in-plane switching (IPS) electrodes is found to be 90
^°
, which is different from the conventional strip electrodes. Although the zigzag structure exhibits a slightly lower transmittance than the strip IPS electrodes, it significantly suppresses the color shift while providing a relatively wide viewing angle.
