ABSTRACT:
Disclosed is a transflective liquid crystal display having a high opening ratio and a single cell gap structure, which includes first and second substrates arranged opposite each other and respectively having reflective and transmissive regions; an opposite direction reflector disposed on the first substrate for reflecting introduced light to the transmissive regions; a color filter formed on the first substrate; transparent electrodes formed on the color filter; a lower polarization plate attached on the first substrate; common electrodes formed on the second substrate; an upper polarization plate attached on the second substrate; and a liquid crystal layer interposed between the first and second substrates, wherein the liquid crystal layer corresponding to the reflective region includes a fixing retardation area in which introduced light is always subjected to a constant phase difference.
