Abstract
Apparatus, methods, systems and devices for high aperture ratio, high transmittance, and wide viewing angle liquid crystal display having first and second substrates each with an alignment layer and polarizer on the interior and exterior surface thereof and a liquid crystal material therebetween forming plural pixels each having a common electrode group and a pixel electrode group each having at least one common and pixel electrode. A fringe field drives the molecules in the regions above and below the electrodes and a horizontal field drives the molecules between the electrode groups to achieve high transmittance. In an embodiment an insulating layer separates the substrate and alignment layer and the pixel electrodes are on the substrate and the common electrodes are on the insulating layer. In another embodiment a compensation film is layered between one of the substrates and corresponding polarizer.
