Provided is a method for manufacturing an organic EL display device, including forming a sealing film to cover an organic EL element. The forming a sealing film includes forming a first inorganic layer to cover the organic EL element, forming a partition on the first inorganic layer, forming an organic layer on the first inorganic layer by applying an organic material inward from the partition on a surface of the first inorganic layer, removing the partition, and forming a second inorganic layer on the first inorganic layer to cover the organic layer.

A film formation method of introducing, into a film formation chamber, a vaporized material obtained by vaporizing a liquid-form organic material in a vaporizing chamber and forming a vapor deposition film composed of the vaporized material on a surface of a film formed substrate placed within the film formation chamber. The method includes: holding an internal temperature of the vaporizing chamber at a lower temperature than a reaction temperature at which the organic material polymerizes; holding an internal pressure of the vaporizing chamber at a saturated vapor pressure of the organic material; setting an internal temperature of the film formation chamber to the same temperature as the internal temperature of the vaporizing chamber; and forming the film in a state where the film formed substrate is held at a temperature lower than the internal temperature of the film formation chamber.

A manufacturing method for an EL device including a mother substrate and a layered body including a light emitting element, the method includes irradiating a laser beams to peel the mother substrate and the layered body from each other, wherein the mother substrate and the layered body contact with each other via a resin layer of the layered body, a protection material is formed on a face of the layered body, the face of the layered body not contacting with the mother substrate, the irradiating includes irradiating a first laser beam and a second laser beam after the first laser beam, and an absorption rate of the second laser beam irradiation by the resin layer is greater than an absorption rate of the second laser beam irradiation by the protection material.

An organic EL display device includes, as an organic layer stopper defining edges of an organic layer, a frame-shaped bank surrounding a display region. An upper face of the bank includes recessed portions and protrusions including a plurality of protrusions, and upper faces of the protrusions includes planar portions.

A method of producing an EL device includes layering a resin layer, a barrier layer and a protective film on a mother glass substrate, the layering including forming, along an end face of the mother glass substrate, an adhesive strengthening layer to strengthen adhesive force between the barrier layer and the protective film.

A film formation device includes an ejecting portion that ejects a first droplet material, and an ejecting portion that ejects a second droplet material having a viscosity greater than a viscosity of the first droplet material. The first and the second droplet materials, upon ejection, form a first film formed by application of the first droplet material and a second film formed by application of the second droplet material, the first film and the second film being adjacent to each other on a surface of an object to be coated.

A flexible display includes an adhesive layer provided on a sealing film including a first inorganic layer, an organic layer, and a second inorganic layer, and a cover layer provided on the adhesive layer. Adhesive layers and cover layers are provided avoiding, in a folding portion, at least a region adjacent to organic EL elements in a plan view.

A hole injection layer provided between a first electrode and each of light emitting layers, and an electron injection layer provided between a second electrode and each of light emitting layers, overlap only inward from an end portions each of the light emitting layers when viewed in plan view.

A sheet portion and a first projection are included. The sheet portion has a sheet shape and includes one or more mask openings. The first projection is provided on a surface of the sheet portion the surface is configured to face a substrate, and the first projection has a frame shape and is formed along an edge of at least one of the one or more mask openings. With this configuration, thin films having dimensions conforming to the design dimensions and preventing blurring are formed over the substrate.

There is provided a display device including: a first substrate that is a silicon substrate and on which a plurality of light-emitting elements is formed; a second substrate including, on a surface, a color filter layer including a plurality of color filters arrayed and a microlens layer including a plurality of microlenses arrayed that are layered in this order, the microlens layer being arranged to face the plurality of light-emitting elements with respect to the first substrate; and an adhesive layer that fills a gap between the first substrate and the second substrate for bonding the first substrate and the second substrate together.
