Patent ID: 10516001

Abstract:
According to a flexible OLED device production method of the present disclosure, after an intermediate region (30i) and flexible substrate regions (30d) of a plastic film (30) of a multilayer stack (100) are divided from one another, the interface between the flexible substrate regions (30d) and a glass base (10) is irradiated with laser light. The multilayer stack (100) is separated into a first portion (110) and a second portion (120) while the multilayer stack (100) is in contact with a stage (210). The first portion (110) includes a plurality of OLED devices (1000) which are in contact with the stage (210). The OLED devices (1000) include a plurality of functional layer regions (20) and the flexible substrate regions (30d). The second portion (120) includes the glass base (10) and the intermediate region (30i). The step of irradiating with the laser light includes making the irradiation intensity of laser light for at least part of the interface between the intermediate region (30i) and the glass base (10) lower than the irradiation intensity of laser light for the interface between the flexible substrate regions (30d) and the glass base (10).
