Claim 6:
7. A manufacturing method for flexible substrate a display device, the display device comprising a display substrate obtained by bending a flexible substrate along a to-be-bent region of the flexible substrate; the flexible substrate being divided into a display region, a binding region on a side of the display region, the to-be-bent region between the display region and the binding region, two transition regions between the to-be-bent region and the display region and between the to-be-bent region and the binding region respectively; the transition regions comprising a plurality of transition sub-regions arranged in a first direction, the first direction being a direction from the display region to the binding region; the manufacturing method comprising:
providing a flexible base;
forming a back film on the flexible base; wherein a portion of the back film is located in the transition regions; in any one of the transition regions, the amount of distribution per unit area of the back film in each of the transition sub-regions gradually decreases in a direction gradually approaching the to-be-bent region; and
bending the flexible substrate, such that both the two transition regions and the to-be-bent region have a bent structure after bending the flexible substrate.
