Abstract: Disclosed is a flexible substrate, which relates to the technical field of display. The flexible substrate includes a first film and a second film arranged from bottom to top in sequence. The second film is arranged to counteract birefringence effect generated by the first film so as to eliminate phase retardation of the flexible substrate. Thus, display effect can be improved, and impacts on a substrate due to increasing of film thickness can also be avoided. Besides, thickness of the flexible substrate can be determined according to actual needs.
