Abstract
A flexible printed circuit and manufacturing method thereof, and a displaying device. A wiring layer is arranged on a flexible substrate, a reinforcing layer is arranged on a side of the flexible substrate away from the wiring layer, the wiring layer comprises a plurality of signal wirings arranged along a first wiring area, a second wiring area, a third wiring area and a fourth wiring area, and the reinforcing layer comprises a first reinforcing structure located in the second wiring area and a second reinforcing structure located in the fourth wiring area. The impact strength of the flexible printed circuit is increased by arranging the first reinforcing structure in the second wiring area of the flexible substrate and arranging the second reinforcing structure in the fourth wiring area of the flexible substrate.
