An electronic ink screen and a manufacturing method therefor are provided. The electronic ink screen comprises a display module (1), a control module (2) and a circuit module (3), wherein the display module (1) comprises a plurality of pixel units, and is configured to perform display by using electronic ink; the control module (2) is configured to convert, by means of an electrode micro-structure, a touch-control signal applied from the outside into an electrical signal change of a corresponding pixel unit, such that the display state of the pixel unit changes from an initial state; the electrode micro-structure comprises sub-electrode micro-structures (4) corresponding to pixel units on a one-to-one basis; and each sub-electrode micro-structure (4) comprises a first nano-electrode (41) and a second nano-electrode (42) which are made of different materials, with the two being arranged to be spaced apart from each other and being configured to be in frictional contact with each other when receiving the touch-
