Patent ID: 10957881

Abstract:
According to a flexible OLED device production method of the present disclosure, a multilayer stack (100) is provided which includes a glass base (10), a functional layer region (20) including a TFT layer (20A) and an OLED layer (20B), and a synthetic resin film (30) provided between the glass base (10) and the functional layer region (20) and bound to the glass base (10). In a dry gas atmosphere whose dew point is not more than −50° C., the multilayer stack (100) is separated into a first portion (110) and a second portion (120), and a surface (30s) of the synthetic resin film (30) is exposed to the dry gas atmosphere, the first portion (110) including the functional layer region (20) and the synthetic resin film (30), the second portion (120) including the glass base (10). The first portion (110) is transported from the dry gas atmosphere to a reduced-pressure atmosphere R, and a protection layer (60) is formed on the surface (30s) of the synthetic resin film (30) in the reduced-pressure atmosphere R.
