Retardation device for a liquid crystal display

摘要

The present invention is related to a retardation device for a liquid crystal display and comprises: an upper retardation device, which has a plurality of retardation layers; a lower retardation device, which has a plurality of retardation layers as well; a LC cell layer, which is between the upper retardation device and the lower retardation device. The present invention adopts a set of retardation plates organized by the upper retardation device and the lower retardation device to apply on a MVA-LCD (Multi-domain Vertical Alignment Liquid Crystal Display) with features of high contrast and wide view angles to promote the contrast and the view angle.
