Title: FLEXIBLE DISPLAY SUBSTRATE AND PREPARATION METHOD THEREFOR, AND FLEXIBLE DISPLAY DEVICE
Abstract:
Provided is a flexible display substrate. The substrate comprises: a flexible base (21); an ultraviolet light reflecting layer (3) which is provided on the flexible base (21) and is capable of reflecting ultraviolet light and letting through visible light, the ultraviolet light reflecting layer comprising a stacking structure (31) composed of alternating first transparent material layers (311) and second transparent material layers (312), wherein the two types of transparent material layers (311, 312) are equal in number and respectively have at least two layers; and the two types of transparent material layers (311, 312) also satisfy: 4nd = λ, where d is the thickness of any transparent material layer, n is the refractive index of the transparent material layers (311, 312), and λ is the wavelength of the ultraviolet light; and a display structure (9) provided above the ultraviolet light reflecting layer (3). The flexible display substrate comprises a flexible array substrate with a low-temperature polycrystalline silicon thin-film transistor.
