摘　　要：A homogeneous-aligned, high-transmission, and fast-response liquid crystal display （LCD） with three-layer electrodes is proposed. The molecules of liquid crystals are more inclined to rotate above and between the pixel electrodes. This induces a much higher transmission than that of the cell driven by the fringe field switching method and a wide viewing angle simultaneously because of the combined fringe and in-plane electric fields. Furthermore, a trigger pulse voltage is applied between the top and common electrodes to forcibly align the liquid crystal molecules vertically to show the transient dark state, which results in a very fast turn-off time （-1 ms）. With high degree of transmission and fast response time, this kind of LCD is a potential candidate for large LCD panels.A homogeneous-aligned, high-transmission, and fast-response liquid crystal display （LCD） with three-layer electrodes is proposed.
