Abstract
A method of manufacturing flexible OLED display panel is provided. The method comprises following steps. Providing a glass carrier, sequentially forming a flexible substrate, a low temperature poly-Si layer and OLED element layer on a surface of the glass carrier; forming a planar layer on a second surface of the glass carrier which is away from the flexible substrate and obtaining a planning OLED display panel; removing the glass carrier by laser lift-off the planning OLED display panel and obtaining the flexible OLED display panel. The method could reduce the problem of lower peeling successful rate caused by the unevenly distributing in the flexible substrate during the laser lift-off process.
