An e-paper display apparatus including an e-paper display panel is provided. The e-paper display panel includes a plurality of pixel circuits arranged in an array. Each of the pixel circuits includes a transistor device, a storage capacitor and a pixel capacitor. A data voltage is configured to drive the storage capacitor and the pixel capacitor, so as to drive the e-paper display panel to display image. The transistor device is an oxide thin-film transistor. An absolute value of the data voltage is greater than or equal to 20 voltages.
