Patent ID: 7859619

Claim:
A transflective liquid crystal display device, comprising: a liquid crystal panel including first and second substrates and a liquid crystal layer between the first and second substrates, the liquid crystal panel including a plurality of pixel regions each including a pixel electrode; a polarizing plate on an outer surface of the second substrate and having a polarizing axis of a first direction; a switching retardation plate on an outer surface of the first substrate and switching operations between a retardation and a non-retardation; a selective reflection plate on an outer surface of the switching retardation plate and having a polarizing axis of a second direction, the selective reflection plate reflecting a light having an optical axis different from the second direction; and a backlight unit on an outer surface of the selective reflection plate, wherein the pixel region is a reflective region in a reflective mode, and the pixel region is a transmissive region in a transmissive mode.
