METHOD FOR MANUFACTURING A FLEXIBLE DISPLAY DEVICE

摘要

PURPOSE: A method for manufacturing a flexible display device is provided to manufacture the flexible display device by simply separating the flexible display device from a supporting substrate using an etching solution. CONSTITUTION: A sacrificing layer(110) is formed on a supporting substrate(200). A buffer layer(120) is formed on the sacrificing layer. The buffer layer covers the entire edge of the sacrificing layer. The edge of the buffer layer and the sacrificing layer is cut in order to expose the sacrificing layer. A thin film element(100) is formed on the buffer layer. The sacrificing layer is eliminated by dissolving the sacrificing layer with an etching solution. The supporting substrate is separated from the buffer layer. [Reference numerals] (AA, BB) Etching solution
