The invention discloses an electronic paper display panel which comprises an array substrate, a common electrode layer and an electrophoresis function layer. The array substrate and the common electrode layer are oppositely arranged, and the electrophoresis function layer is located between the array substrate and the common electrode layer. The array substrate is provided with a plurality of sub-pixel areas distributed in an array mode. The array substrate comprises a substrate layer, a driving circuit layer and a pixel electrode layer, wherein the driving circuit layer and the pixel electrode layer are sequentially located on the substrate layer. The driving circuit layer comprises a plurality of thin film transistors which are positioned in the sub-pixel region and are sequentially connected in series; the pixel electrode layer comprises a plurality of pixel electrode blocks which are arranged in one-to-one correspondence with the plurality of sub-pixel areas, and each pixel electrode block is electrically
