Title: FLEXIBLE DISPLAY SUBSTRATE AND PREPARATION METHOD THEREFOR
Abstract:
A flexible display substrate can effectively release stress accumulated on the flexible display substrate, thereby reducing the probability of fracture of a metal wire and an insulation layer in a process in which a flexible display screen body is bent. A flexible display substrate preparation method can prevent the aging of a flexible display screen and can prolong the service life of the flexible display screen. The provided flexible display substrate comprises a flexible substrate (1), at least one conductive composite layer is disposed on the flexible substrate, and the conductive composite layer comprises two metal layers (3, 5) and an insulation layer (4) located between the two metal layers. Each of the two metal layers comprises metal wire sections (7) disposed at an interval, contact holes (6) are formed in the insulation layer, and the metal wire sections of the two metal layers are connected by means of metal in the contact holes, so as to form a consecutive conductive metal wire (8).
