A planar light source including a transflective film, a plurality of cold cathode fluorescence flat lamps and at least one reflective component to provide a uniform light source is described. A portion of the light emitted from the emitting areas of the cold cathode fluorescence flat lamps passes through the transflective film, and the other portion of the light is reflected to the reflective component by the transflective film. Then, the light is reflected to the dark areas between the emitting areas to compensate the brightness of the dark areas. When the brightness of the dark areas is compensated, the planar light source provides a uniform light without dark stripes.
