Abstract
After an intermediate region and flexible substrate regions of a plastic film of a multilayer stack are divided from one another, the interface between the flexible substrate regions and a glass base is irradiated with laser light. The multilayer stack is separated into first and second portions while the multilayer stack is in contact with a stage. The first portion includes a plurality of OLED devices in contact with the stage. The OLED devices include a plurality of functional layer regions and the flexible substrate regions. The second portion includes the glass base and the intermediate region. The step of irradiating includes first and second laser light scanning. Irradiation intensity is modulated such that the irradiation intensity for at least part of the interface between the intermediate region and the glass base is lower than the irradiation intensity for the interface between the flexible substrate regions and the glass base.
