A liquid crystal display (LCD) comprises an array substrate and a color filter substrate, which are assembled together and sandwich liquid crystal therebetween. The array substrate comprises a gate line, a first data line and a second data line, which define a pixel region, a first pixel electrode and a first thin film transistor (TFT) for controlling the first data line to provide a first data voltage to the first pixel electrode in the pixel region, and a second pixel electrode and a second TFT for controlling the second data line to provide a second data voltage to the second pixel electrode. The color filter substrate comprises black matrixes and a color resin unit. The position of the first pixel electrode corresponds to the position of the color resin unit between the black matrixes so as to display a first image on a side of the color filter substrate in a light transmission mode; the position of the second pixel electrode corresponds to the position of the color resin unit on the black matrixes so as to display a second image on a side of the array substrate in a light reflection mode.
