A transflective liquid crystal display comprising a plurality of pixels, each pixel comprising a liquid crystal layer ( 3 ) sandwiched between a front substrate ( 1 ) and a back substrate ( 2 ), and an optical layer ( 7 ) comprising a birefringent material, said pixels being divided into at least one transmissive ( 5 ) and at least one reflective subpixel ( 4 ), and said optical layer ( 7 ) being at least partly sandwiched between the liquid crystal layer ( 3 ) and one of said front substrate ( 1 ) or back substrate ( 2 ), and being patterned into domains ( 8, 9 ), each domain covering at least part of a reflective subpixel ( 4 ) or at least part of a transmissive subpixel ( 5 ).
