In a transflective liquid crystal display comprising a plurality of pixels, each is divided into three color sub-pixels in red, green and blue. Each of the color sub-pixels is further divided into a main sub-pixel and an auxiliary sub-pixel. The main sub-pixel comprises a transflective area and a reflective area. The auxiliary sub-pixel can be entirely transmissive, reflective or partially transmissive and reflective. The liquid crystal display further comprises a plurality of first gate lines for electrically controlling the main sub-pixels and a plurality of second gate lines for electrically controlling the auxiliary sub-pixels. The auxiliary sub-pixels may have a color filter for partially filtering light encountering the auxiliary sub-pixels according to the color of the color sub-pixels.
