Abstract
A transflective liquid crystal display device includes first and second transparent substrates opposing each other, a transparent pixel electrode on an inner surface of the first transparent substrate, a first passivation layer on the transparent pixel electrode, a reflective pixel electrode on the first passivation layer, the reflective pixel electrode having a through hole passing through the first passivation layer such that the through hole exposes the transparent pixel electrode, a lower polarizer on an exterior surface of the first transparent substrate, a back light below the lower polarizer, a color filter layer on an inner surface of the second transparent substrate, a second passivation layer on the color filter layer, a common electrode on the second passivation layer, the common electrode having a concavity formed toward the upper substrate, the concavity corresponding to the through hole of the reflective electrode, a retardation layer on an exterior surface of the second transparent substrate; an upper polarizer on the retardation layer; and a liquid crystal layer between the common electrode and the reflective pixel electrode, and between the concavity of the common electrode and an exposed portion of the transparent pixel electrode.
