Abstract

We propose a new electrode structure for the fringe-field switching mode, which not only has a smaller color shift but also transmits more light than the chevron-type structure. While the chevron-type electrode structure mainly uses the different directions of the electric field, the proposed structure makes use of position-dependent strengths as well as different directions of the electric field. Position-dependent electric field strengths bring about rotation of LCs different from position to position in a pixel, which further reduce the color shift by using the multi-domain effect.
