Abstract
A nematic liquid crystal display includes a first substrate provided with a common electrode, a second substrate provided with a pixel electrode, the second substrate being arranged to extend in parallel to the first substrate, and a liquid crystal cell which includes a nematic liquid crystal with a splay distortion. In the liquid crystal domains of a first type which are different in tilted-up direction of liquid crystal molecules coexist, and domains of a second type which are different in twist direction of liquid crystal molecules coexist. The liquid crystal may include a polymer that is a polymerized monomer or oligomer.
