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.
