To provide a transflective liquid crystal display capable of increasing the reflectivity in the pixel without unduly degrading the color quality of a liquid crystal panel and to provide an improving method of display quality thereof.

The transflective liquid crystal display having a plurality of pixels comprises: a first substrate having a common electrode; a second substrate; and a liquid crystal layer disposed between the first and the second substrates and comprising a plurality of layer segments associated with the plurality of pixels, wherein at least some of the pixels comprise a plurality of sub-pixels and wherein at least three of the sub-pixels are color sub-pixels and at least one of the sub-pixels is a fourth sub-pixel, and wherein each of the color sub-pixels comprises a transmission area having a transmissive electrode disposed on the second substrate and a reflection area having a reflective electrode disposed on the second substrate, and the fourth sub-pixel comprises a further reflective electrode disposed on the second substrate. The improving method of display quality is adopted.
