A reflective display device may include pixels. Each pixel may include sub-pixels. Each sub-pixel may include first and second substrates spaced apart from each other; a driving unit formed on a top surface of the first substrate; a reflective layer, acting as a first electrode to which a voltage is applied by the driving unit, disposed above the driving unit; a second electrode formed on a bottom surface of the second substrate; a color filter layer disposed between the reflective layer and the second electrode; and a polymer dispersed liquid crystal (PDLC) layer. If the color filter layer is formed on the reflective layer; then the PDLC layer may be disposed between the second electrode and color filter layer. If the color filter layer is formed on a bottom surface of the second electrode, then the PDLC layer may be disposed between the reflective layer and color filter layer.
