We have developed a high-transmittance in-plane switching (HT-IPS) liquid crystal display (LCD) using special electrode design on the same substrate. The featured electrode configuration generates substantial horizontal electric fields between the electrode groups, and fringe fields with rich horizontal components within the regions of electrode groups. The former is similar to the IPS mode and the latter is similar to the fringe-field switching (FFS) mode. The HT-IPS mode exhibits a high transmittance (> 90 % of twisted nematic (TN) mode), as well as wide viewing angle for cells using both positive and negative dielectric anisotropy LC materials. In addition, we also compare the electro-optical performance of the HT-IPS with IPS and FFS cells under the same conditions
