According to a flexible light-emitting device production method of the present disclosure, 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 lift-off light. The multilayer stack () is separated into a first portion () and a second portion () while the multilayer stack () is in contact with a stage (). The first portion () includes a plurality of light-emitting devices () which are in contact with the stage (). The light-emitting 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 with the lift-off light includes the first light scanning for scanning the interface in a first direction with the light in the form of a line beam, and the second light scanning for scanning the interface in a second direction with the light. In each of the first and second light scanning, the irradiation intensity is modulated such that the 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 ().

Method and device for manufacturing flexible light emission device

A vapor deposition mask is provided with: a resin film, which has at least one of first to third opening patterns in which first to third openings, for forming first to third subpixels that configure one pixel of a display panel, are disposed with a fixed periodicity; and a metal support layer, which is bonded to the resin film and has an opening pattern for fourth openings that are formed so as to be able to encompass all of the first to third openings of the resin film. In regions of the resin film exposed by the fourth openings of the metal support layer, one or two of the first to third openings of the resin film are formed.

The organic barrier layer () is present on at least a part of a flat portion, and a surface of the organic barrier layer () is oxidized. A method for producing the organic EL display device () in an embodiment includes the step of asking the organic barrier layer.

Organic EL display device and method for manufacturing same

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.
