An organic-EL display apparatus comprises an organic layer for each of a plurality of pixels each comprising at least three sub-pixels having substantially rectangular shapes. A first sub-pixel and a second sub-pixel are arranged in parallel with each other such that a long side of the first sub-pixel and a long side of the second sub-pixel are substantially parallel with each other; and a long side of a third sub-pixel is substantially parallel with a short side of each of the first and second sub-pixels. In the first and second sub-pixel, a variation in a thickness of the organic layer through a long-side direction is larger than a variation in the thickness through a short-side direction; and in the third sub-pixel, a variation in a thickness of the organic layer through a short-side direction is larger than a variation in the thickness through a long-side direction.

A vapor deposition mask (100A) includes a base film (10A) including a plurality of first openings (13A) and containing a polymer; a composite magnetic layer (20A) formed on the base film (10A), the composite magnetic layer (20A) including a solid portion (22A) and a non-solid portion (23A); and a frame (40A) joined to a peripheral portion of the base film (10A). The plurality of first openings (13A) are formed in a region corresponding to the non-solid portion (23A); and the composite magnetic layer (20A) contains soft ferrite powder having an average particle diameter shorter than 500 nm and a resin.

A material of the vapor deposition mask that a resin film layer is disposed on a surface of a metal film layer on which one or more openings are formed is welded on a metal frame in a manner so that the resin film layer faces outward under a condition that a predetermined tension is applied in a predetermined direction; the metal frame is held on a base mount; a taper forming member/material having a reflection surface or the like is disposed to facing the metal film layer which is inward of the metal frame; laser beams are irradiated from above the resin film layer.

An organic EL display device with higher resolution, suppressed power consumption while being driven and low manufacturing cost, and no color mixing and color shifting between subpixels adjacent to each other is provided. In a B subpixel, a first separation layer is provided between a common blue-light-emitting layer and a common green-light-emitting layer. In a G subpixel, a second separation layer is provided between the common green-light-emitting layer and a common red-light-emitting layer.

Provided is an organic EL light-emitting element including an organic layer coating film 25 which is formed into a super-fine pixel pattern by using an organic material that is an oligomer having a molecular weight of 300-5000. Also provided is a method for manufacturing the organic EL light-emitting element. The coating film 25 is formed by dropping liquid microdroplets of approximately 0.05-1 pL.

A sealing structure according to an embodiment of the present invention is provided with: first and second substrates that are opposed to each other; an electronic element that is formed between the first and second substrates; and a sealant that closes the gap between the first and second substrates, at the outer periphery of the electronic element, wherein the sealant includes a low-melting point glass material and a plurality of spacers, and the spacers have melting points higher than the softening point of the low-melting point glass material.

The method for forming a light-emitting layer includes the steps of: preparing an ink containing particles and a dispersion medium with a boiling point of 200 C. or more at atmospheric pressure, the particles containing light-emitting semiconductor nanocrystals and a dispersant supported on the semiconductor nanocrystals; supplying the ink to a substrate to form a coating film on the substrate; placing the substrate, on which the coating film is formed, in a chamber, and reducing the internal pressure of the chamber to a first pressure in the range of 1 to 500 Pa and holding the first pressure for 2 minutes or more to remove the dispersion medium from the coating film; and reducing the internal pressure of the chamber to a second pressure that is lower than the first pressure and holding the second pressure for a predetermined time to further remove the dispersion medium from the coating film.

An organic EL element including light emitting layers is formed above a first region of a main surface of a back film. A plurality of terminal portions are formed above a second region of the main surface of the back film. A cover film including an opening is provided as an uppermost layer above the main surface of the back film.

A portion of a resin film is precisely cut out when the resin film is peeled off. A rear surface of a glass substrate on which a protrusion is formed is irradiated with a laser beam to peel a resin film from the glass substrate. Then, the protrusion and the resin film formed on the protrusion are left on the glass substrate.

A deposition mask apparatus includes: a deposition mask having a plurality of mask through-holes extending from a first surface which is positioned closer to the substrate, to reach a second surface which is positioned opposite to the first surface; and a frame provided with an opening which is overlapped with a part of the deposition mask, the frame supporting the deposition mask.
