Abstract:
1. A transflective liquid crystal display comprising: a first substrate having a first vertical alignment film, a first non-conductive layer, and a transparent common electrode layer having a repetitive pattern, said transparent common electrode layer and said first non-conductive layer being sandwiched between said vertical alignment film and said first substrate; a second substrate having a second vertical alignment film, a second non-conductive layer, a non-patterned transparent electrode, and a patterned reflector, said patterned reflector, said non-patterned transparent electrode, and said second non-conductive layer being sandwiched between said second vertical alignment film and said second substrate, said patterned reflector having a pattern that is an approximately mutually complementary pattern to said transparent common electrode layer repetitive pattern to form alternating transmissive display regions and reflective display regions on said second substrate, said patterned reflector on said second substrate and said repetitive pattern of said transparent common electrode layer on said first substrate being arranged so that a substantially longitudinal electric field is generated in said transmissive display regions and a substantially fringing field is generated in said reflective display regions; and a liquid crystal material sandwiched between said first vertical aliment film and said second vertical alignment film.
