A color filter for a transflective liquid crystal display (LCD) includes a transparent substrate (2011), a color filter layer (2012) covering the transparent substrate, a transparent layer (2013) covering the color filter layer, and a transparent electrode (2014). The color filter layer comprises a plurality of black matrix units (2016) and a plurality of color units (2015). Each color unit has two first portions (r) that correspond to a reflective mode, and a second portion (t) that corresponds to a transmissive mode. The second portion is preferably twice as thick as the first portions. A transflective LCD using the color filter is also described.
