Each pixel unit is disposed in one of the pixel regions corresponding thereto and includes a plurality of and a white filter film. Each color filter film is disposed in one of the first sub-pixel regions corresponding thereto and the white filter film is disposed in the second sub-pixel region. Since the area of the white filter film is larger than the area of each color filter film, the color filter has high light-transmittance. The transparent electrode layer is disposed on the pixel units. Furthermore, a color reflective display device with the color filter is disclosed.
