Abstract

There is provided an electronic paper display apparatus and a production method and a driving method thereof. The electronic paper display apparatus has: a first electrode layer and a thin-film transistor array layer, which are opposite; an electronic paper ink layer, which is between the first electrode layer and the thin-film transistor array layer; and a second electrode layer, which is on a side of the thin-film transistor array layer away from the electronic paper ink layer and is configured to be capable of forming an electric field for removing an image of the electronic paper ink layer or resetting the electronic paper ink layer together with the first electrode layer.
