Thereby, the positive and negative of the potential difference between the common electrode layer 10 and the conductive layer 40 is switched, thereby realizing the switching between the writing and the eraser-type cleaning of the electronic paper device. [0022] The electronic paper device of the present invention can support handwriting, touch position recognition, and general electronic paper display functions. 099109182 Form No. A0101 Page 10 of 18 0992016377-0 201133102 [Simple Description of the Drawings] [0023] FIG. 1 is a detailed structural view of an electronic paper apparatus of the present invention. 2 is a schematic structural view of an eraser-type erase function portion of an electronic paper device according to an embodiment of the present invention. 3 is a schematic structural view of an e-paper apparatus performing an eraser erasing function according to another embodiment of the present invention.
