A reflective liquid crystal display panel capable of performing data programming and/or data erasing via a polarized light is provided. The reflective liquid crystal display panel includes a first substrate, a second substrate, a liquid crystal layer, a transflective film, a retarder and a polarizer. The second substrate is disposed over the first substrate. The liquid crystal layer is located between the first substrate and the second substrate and an optical aligned material is doped in the liquid crystal layer. The transflective film is disposed below the first substrate, and the transflective film allows the polarized light to pass through, so that the orientation of the optical aligned material doped liquid crystal layer can be controlled by the polarized light. The transflective film reflects external light source. The retarder is disposed between the transflective film and the first substrate. The polarizer is disposed on the second substrate.
