Display substrate, method of manufacturing the same and electrowetting display panel having the display substrate

An electrowetting display panel comprising:

• a display substrate comprising a first base substrate, a reflection-polarization member disposed on the first base substrate to reflect and polarize incident light, a first electrode disposed on the reflection-polarization member, and a first pixel wall disposed on the first electrode, wherein the first pixel wall defines a unit pixel area;
• an opposite substrate positioned opposite to the display substrate, the opposite substrate comprising a color filter and a second electrode formed on the color filter;
• and
• a liquid layer interposed between the display substrate and the opposite substrate, the liquid layer comprising a first liquid having a material absorbing light and a second liquid having a specific gravity different from the specific gravity of the first liquid.
