Abstract

A TFT array substrate, an electronic paper display panel and method for manufacturing the same are disclosed. The electronic paper display panel includes: a first transparent substrate, and an array of storage capacitors located on an inner side of the first transparent substrate. Each of the storage capacitors includes a common electrode located on the first transparent substrate, a transparent capacitor medium layer located on the common electrode, and a pixel electrode (44) located on the transparent capacitor medium layer. The display panel also includes an electronic paper film located on the TFT array substrate, a transparent electrode located on the electronic paper film, and a second transparent substrate located on the transparent electrode. A double-sided display may be realized by the electronic paper display panel.
