FLEXIBLE DISPLAY SUBSTRATE AND PREPARATION METHOD THEREFOR, AND FLEXIBLE DISPLAY DEVICE

摘要

The present invention provides a flexible display substrate and a manufacturing method thereof, and a flexible display device, and belongs to the field of flexible display technology. The present invention can solve the problem that the display structure in the existing flexible display substrate is likely to be damaged at the time of laser lift-off. The flexible display substrate of the present invention comprises: a flexible base and a display structure, and a reflective layer provided between the flexible base and the display structure. The manufacturing method of a flexible display substrate of the present invention comprises: forming a flexible material layer on a base; forming a reflective layer on the flexible material layer; forming a display structure; separating the flexible material layer from the base by means of laser lift-off to obtain the flexible display substrate. The present invention is applicable to flexible display devices, particularly to a top-emitting type organic light emitting diode display device and a flexible array substrate with a low-temperature polysilicon thin film transistor.
