Abstract
A wide viewing angle liquid crystal display is provided. The present invention includes a first substrate, a second substrate, a liquid crystal layer, a plurality of pixels, a common electrode, a plurality of protrusions, a plurality of control electrodes, a first orientation layer and a second orientation layer. The liquid crystal layer is interposed between the first substrate and the second substrate. The plurality of pixels are arranged in a matrix and disposed on the first substrate, each pixel has a pixel electrode and a switching means connected to it. The common electrode is disposed on the second substrate. The plurality of protrusions are composed of dielectric material and at least one of the plurality of protrusions is disposed on each pixel electrode. Each of the plurality of control electrodes is disposed on top of one of the plurality of protrusions. The first orientation layer overlays the homeotropic surface which covers the plurality of pixel electrodes, the plurality of protrusions, and the plurality of control electrodes. The second orientation layer overlays the surface of the common electrode.
