ABSTRACT:
An OCB type liquid crystal display having first and second substrates opposed to each other via a liquid crystal layer such that rubbing directions of the first and second substrates become parallel to each other, a plurality of pixel electrodes which correspond to respective pixels, and a common electrode formed on the second substrate which receives a reference voltage commonly to a plurality of the pixels. A first transition nucleus area is formed in the first substrate layer and has a plurality of continuous slant surfaces having a saw-tooth cross sectional profile, and a second transition nucleus area is formed in the second substrate and has a plurality of continuous slant surfaces having a saw-tooth cross sectional profile. The slant surfaces in the first and second transition nucleus areas oppose to each other and slope toward mutually opposite angular directions.
