Abstract:
A wide-viewing angle display device which is a multi-domain vertical alignment (MVA) mode liquid crystal display (LCD) device, comprising:an upper glass substrate and a lower glass substrate disposed parallel to each other; a liquid crystal layer of positive dielectric anisotropy formed in a space between the upper glass substrate and the lower glass substrate; a plurality of first protrusions formed on the inner surface of the upper glass substrate; a plurality of common electrodes formed on the tops of the first protrusions, respectively; a plurality of second protrusions formed on the inner surface of the lower substrate, in which the first protrusions and the second protrusions are arranged alternately; and a plurality of pixel electrodes formed on the tops of the second protrusions, respectively, in which the pixel electrodes and the common electrodes are arranged alternately; wherein, after applying a voltage to the display device, a transverse electrical field is generated between the common electrode and the pixel electrode to drive the liquid crystal molecules, and two alignment domains are formed at both sides of the first protrusion.
