The invention provides a flexible printed circuit board, a pressing method of the flexible printed circuit board and a display device of the flexible printed circuit board. The flexible printed circuit board comprises a first flexible printed circuit board part and a second flexible printed circuit board part which are connected with one another, wherein the first flexible printed circuit board part has a golden finger end which is equipped with a metal terminal capable of transmitting an electric signal; the second flexible printed circuit board part is equipped with a protective end, wherein the protective end and the golden finger end are positioned at the same side of the flexible printed circuit board. The flexible printed circuit board provided by the invention can be used for enabling a polaroid to bind a non-yellowing area subjected to the flexible printed circuit board process, so that the appearance and the light transmission function of the polaroid are normal, and therefore, a touch circuit on the polaroid does not have conduction abnormity due to temperature distortion.
