Abstract
The present disclosure relates to a composite substrate adapted for manufacturing a flexible display screen. The composite substrate includes a base substrate, a sacrificial layer, and a flexible layer. The sacrificial layer is located on the base substrate. The flexible layer is located on the sacrificial layer. The sacrificial layer is an inorganic layer which contains hydrogen element and is semi-transparent. The present disclosure further provides a method for manufacturing a flexible display screen, comprising: depositing a sacrificial layer on a base substrate, the sacrificial layer is an inorganic layer, the inorganic layer contains hydrogen element and is semi-transparent; forming a flexible layer on the sacrificial layer; forming electronic components on the flexible layer; and irradiating the sacrificial layer by a laser beam to cause the hydrogen element in the sacrificial layer to form hydrogen gas bubbles, so as to separate the base substrate and the sacrificial layer.
