Embodiment 1

[0043] Such as Figure 3 to Figure 7 As shown, this embodiment provides a flexible display substrate, which includes:

[0044] flexible substrate 21;

[0045] A reflective layer 3 disposed on the flexible substrate 21;

[0046] A display structure 9 disposed above the reflective layer 3 .

[0047] Wherein, the “display structure 9 ” refers to all structures for display formed on the reflective layer 3 . According to different types of flexible display substrates, the display structure 9 may include: thin film transistors, gate lines, gate insulating layers, data lines, planarization layers (PLN), passivation layers (PVX), capacitors, anodes, cathodes, organic light-emitting layers , pixel definition layer (PDL), color filter film, etc.

[0048] In the flexible display substrate of this embodiment, a reflective layer 3 is provided between the flexible substrate 21 and the display structure 9, so, as Figure 7 As shown, during laser lift-off, the reflective layer 3 can refl...

Abstract

The invention provides a flexible display substrate, a manufacturing method of the flexible display substrate and a flexible display device, and belongs to the technical field of flexible display. The problem that a display structure in an existing flexible display substrate is probe to being damaged in the laser lift-off process can be solved. The flexible display substrate comprises a flexible base, a display structure and a reflective layer arranged between the flexible base and the display structure. The manufacturing method of the flexible substrate comprises the steps of forming a flexible material layer on the base, forming the reflective layer on the flexible material layer, forming the display structure and separating the flexible material layer from the base through the laser lift-off mode to obtain the flexible display substrate. The flexible display substrate and the manufacturing method of the flexible display substrate are suitable for the flexible display device, especially a flexible top transmission type organic light emitting diode display device, and a flexible array substrate with a low-temperature polycrystalline silicon thin film transistor.

Description

technical field [0001] The invention belongs to the technical field of flexible display, and in particular relates to a flexible display substrate, a preparation method thereof, and a flexible display device. Background technique [0002] With the development of technology, flexible display devices have been applied more and more widely, and flexible display devices include different types such as organic light emitting diode display devices and electrophoretic display devices. Obviously, the substrate of the display substrate of the flexible display device (such as the flexible array substrate of the flexible organic light-emitting diode display device) must be a flexible substrate, and the flexible substrate is mainly made of organic materials such as polyimide and polyethylene terephthalate. production. [0003] Since the flexible substrate is prone to deformation, it is difficult to locate, transport and store the flexible substrate during the preparation process of the...
