The invention relates to a touch panel, a manufacturing method of the touch panel and a display device. The touch panel comprises a pressure induction layer and a position induction layer, wherein the pressure induction layer comprises a first electrode layer, a second electrode layer and an organic thin film; the organic thin film is arranged between the first electrode layer and the second electrode layer and is used for generating currents according to induced pressures; the currents are transmitted to a processor through the first electrode layer and/or the second electrode layer; the processor is used for generating pressure signals according to the currents. When the pressure induction layer is under pressures, the organic thin film is capable of directly generating currents according to the pressures, and then the processor is capable of generating corresponding pressure signals according to different currents so as to trigger 3D touch operation. The first electrode layer and the second electrode layer only play a role in electric conduction, and currents or voltages are not supplied for the first electrode layer and the second electrode layer, so that the circuit layout is simplified.
