An electro-wetting display device includes a first substrate; a second substrate opposite to the first substrate; a plurality of side walls interposed between the first and second substrates, the side walls being arranged in a matrix and cooperating with the first and second substrates to form a plurality of spaces; a first polar liquid disposed in each of the spaces; a second, colored, non-polar liquid disposed in each of the spaces. The second liquid is immiscible with the first liquid. The second substrate includes a reflective electrode and a hydrophobic insulating layer disposed on the reflective electrode. The reflective electrode includes a first metal layer and a transparent protective layer, and the transparent protective layer is interposed between the metal layer and the hydrophobic insulating layer.
