ABSTRACT:
The invention relates to optically compensated bend (OCB) mode liquid crystal display devices and fabrication methods thereof. The OCB mode liquid crystal display includes a first substrate, a second substrate and a liquid crystal layer interposed therebetween. A first pixel electrode is disposed on the first substrate. A second pixel electrode is disposed overlying the first pixel electrode with a dielectric layer interposed therebetween such that a discontinuous fringe field is formed at the edge of the second pixel electrode. A first alignment layer is disposed on the first substrate covering the first and second pixel electrode. A common electrode is disposed on the second substrate, and a second alignment layer is disposed on the second substrate covering the common electrode.
