Claim Text:
1. A color electrophoretic display panel, comprising: a plurality of pixel units each of which comprises more than two different colors of electrophoretic particles, and threshold voltages driving different colors of electrophoretic particles being different, wherein, the color electrophoretic display panel comprises: an upper substrate; a lower substrate opposite to the upper substrate; a plurality of pixel electrodes spaced apart, provided at a side of the lower substrate facing the upper substrate, and each of the pixel electrodes corresponding to one pixel unit; a common electrode provided at a side of the upper substrate facing the lower substrate; an electrophoretic layer provided between the pixel electrodes and the common electrode and comprising an oil solution which is mixed with the more than two different colors of electrophoretic particles; and a partition wall which partitions the respective pixel units and partitions the electrophoretic layer within areas of the respective pixel units, a material of the common electrode is a transparent conductive high molecular material, and the common electrode is formed with nano gold particles at its surface.
