Abstract
The present invention provides an improved type of liquid crystal (LC) display device with wide-viewing angle and high optical transmittance. The LC display of the present invention consists of: at least one LC alignment apparatus, which makes the LC molecules within the display area forming a continuous-domain or multi-domain alignments, and hence improve its wide-viewing-angle characteristics; a LC layer formed by Nematic type LC with chiral dopants, and with optimal parameters of the optical path difference Δnd and LC rotations of d/p ratio, such that LC molecules can be aligned along all radial directions to achieve optimal transmittance, and thus producing an wide-viewing-angle LC display improved transmittance without the formation of dark fringes in the display area.
