An electrophoretic display (“EPD”) panel includes a display substrate and an electrophoretic film. The display substrate includes a display switching element electrically connected to a display gate line and a data line crossing the display gate line, a pixel electrode electrically connected to the display switching element, and a sensing switching element electrically connected to a sensing gate line and the data line to detect a light quantity. The electrophoretic film is combined with the display substrate. The electrophoretic film includes a plurality of charged particles. Thus, a bias signal of the sensing switching element is delivered through the data line applying the data signal, so that a manufacturing process of the EPD panel may be simplified.
