Flexible OLED device, method for manufacturing same, and support substrate

Abstract

According to a method for producing a flexible OLED device of the present disclosure, a multilayer stack (100) is provided, the multilayer stack including a base (10), a functional layer region (20) which includes a TFT layer and an OLED layer, a flexible film (30) provided between the base and the functional layer region and supporting the functional layer region, and a release layer (12) provided between the flexible film and the base and bound to the base. The release layer is irradiated with lift-off light (216) transmitted through the base, whereby the flexible film is delaminated from the release layer. The release layer is made of a polycrystalline of tantalum nitride.
