Abstract
The present invention provides a flexible display substrate, comprising a flexible base; an ultraviolet reflecting layer disposed on the flexible base and capable of reflecting ultraviolet light and transmitting visible light, comprising a stacked structure consisting of alternate first transparent material layers and second transparent material layers, wherein the numbers of the two kinds of transparent material layers are equal, and are at least two respectively, and the two kinds of transparent material layers also satisfy: 4nd=λ, wherein d is the thickness of any one of the transparent material layers, n is a refractive index of the transparent material layer and λ is the wavelength of ultraviolet light; and a display structure disposed above the ultraviolet reflecting layer. The present invention is applicable to flexible display substrates, particularly flexible array substrates comprising low-temperature polycrystalline silicon thin film transistors.
