The invention provides a flexible printed circuit board, a touch plate and a display with a touch function. The flexible printed circuit board comprises a key area and a transmission area, wherein the key area is provided with a touch electrode; and the transmission area is used for providing signals to an external circuit. The touch plate comprises the flexible circuit board. The display comprises the touch plate, and the transmission area is bent around the display panel. The touch electrode is directly formed on a main FPC (flexible printed circuit), a manufacturing and adhering process on an extra independent FPC with a touch function can be reduced, and the process and the structure are simplified. Furthermore, the transmission area, which is connected to the external circuit, on the FPC is separated from the key area for fulfilling the touch function, so that the risk on breakage of the FPC when the FPC is bent can be reduced.
