Description

technical field

[0001] The present application relates to the field of display technology, in particular to a flexible display substrate, a manufacturing method thereof, and a display device. Background technique

[0002] With the development of display technology, display devices are gradually developing towards a narrow frame or even a frameless direction. Currently, display devices with narrow borders are mainly flexible display devices.

[0003] The flexible display device includes a flexible display substrate. The flexible display substrate has an opposite display surface and a non-display surface. The display surface has a display area and a non-display area. The binding area bound to the flexible display substrate can be bent to the side where the non-display surface is located to achieve a narrow frame or even no frame of the display device. When the binding area is bent to the side where the non-display surface is located, the non-display The bent region of the re...
