Abstract: The present invention relates to a multi-domain, specifically 4-domain, liquid crystal display and a method for manufacturing the same. In one aspect, the liquid crystal display includes a pair of opposed substrates and a liquid crystal injected and sealed between the substrates. A first region and a second region on the first substrate have different alignment directions due to a photosensitive alignment film formed on the first substrate. Each pixel on the second substrate exhibits four different liquid crystal alignment directions when an electric field is applied. This occurs because a fringe field is generated by a slit-patterned pixel electrode of the second substrate, and different alignment directions are formed in the first substrate.

Abstract: A liquid crystal display device and a method for fabricating a liquid crystal display device wherein two domains are provided within each pixel cell so as to prevent flicker and to widen a viewing angle. In the liquid crystal display device, a common electrode is formed on a first substrate in such a manner to be divided into at least two electrodes. An alignment film is coated on the first substrate provided with the common electrode and a second substrate. A ferroelectric liquid crystal layer is injected between the first substrate and the second substrate to form at least two domains having a liquid crystal alignment state opposed to each other on a basis of a dividing line of the common electrode.
