  • Patent number: 9748521
    Abstract: A flexible display and method of manufacturing the same are disclosed. In one aspect, the method includes forming a metal peroxide layer over a supporting substrate, forming a metal layer over the metal peroxide layer and forming a flexible substrate over the metal layer. The method also includes forming a display layer over the flexible substrate, irradiating the supporting substrate with laser light in a direction from the supporting substrate to the flexible substrate so as to form a metal oxide layer and separating the supporting substrate from the flexible substrate with the metal oxide layer as a boundary between the supporting substrate and the flexible substrate.

  • Publication number: 20150187849
    Abstract: In a method of manufacturing a flexible substrate, a preliminary sacrificial layer that includes polyimide is formed on a carrier substrate. The preliminary sacrificial layer is transformed into a sacrificial layer that includes a modified polyimide. A base substrate layer that includes polyimide is formed on the sacrificial layer. A device structure is formed on the base substrate layer. A combination of the base substrate layer and the device structure is separated from the carrier substrate.
