Flexible display panel and fabricating method thereof

A fabricating method of a flexible display panel, comprising:

• forming a flexible substrate on a glass plate, the flexible substrate having a surface with a first display region, a second display region and a non-display region, the first display region being adjacent to the second display region and the non-display region surrounding the first display region and the second display region;
• forming a plurality of electro-phoretic pixel units in the first display region of the surface of the flexible substrate;
• forming a plurality of electro-wetting pixel units in the second display region of the surface of the flexible substrate;
• forming a transparent protecting layer to cover the electro-phoretic pixel units and the electro-wetting pixel units;
• forming a driving circuit in the non-display region of the flexible substrate, wherein the driving circuit is electrically connected to the electro-phoretic pixel units and the electro-wetting pixel units;
• and
• separating the flexible substrate from the glass plate,
• wherein the steps for forming the electro-phoretic pixel units and the electro-wetting pixel units comprise:
• forming a plurality of first thin film transistors, a first reflecting layer, a plurality of second thin film transistors and a second reflecting layer on the flexible substrate, wherein the first thin film transistors and the first reflecting layer are located in the first display region, and the second thin film transistors and the second reflecting layer are located in the second display region;
• forming a plurality of first pixel electrodes and a plurality of second pixel electrodes on the flexible substrate, wherein the first pixel electrodes are formed above the first reflecting layer, and each of the first thin film transistors is electrically connected to one of the first pixel electrodes corresponding thereto, the second pixel electrodes are formed above the second reflecting layer, and each of the second thin film transistors is electrically connected to one of the second pixel electrodes corresponding thereto;
• forming an electro-phoretic layer with a plurality of charged particles above each of the first pixel electrodes;
• forming an electro-wetting layer above each of the second pixel electrodes, comprising:
