A display unit with touch function, a manufacturing method thereof and a display device. The display unit includes an array substrate and an opposing substrate which are cell-assembled together, and a display function layer disposed between the array substrate and the opposing substrate. First electrodes and second electrodes which do not contact each other are formed on the array substrate and/or the opposing substrate and are respectively taken as driving electrodes and sensing electrodes; materials for forming the first electrode and/or the second electrodes include topological insulators; and the first electrode and/or the second electrodes are provided with two-dimensional (2D) nanostructures and adhered to the array substrate and/or the opposing substrate through an adhesion layer. The display unit solves the problems of slow touch response rate, easy heat generation and large power consumption due to high resistance of first electrodes and second electrodes on the conventional display unit.
