Abstract:
First and second vapor deposition particles (91a, 91b) discharged from first and second vapor deposition source openings (61a, 61b) pass through first and second limiting openings (82a, 82b) of a limiting plate unit (80), pass through mask opening (71) of a vapor deposition mask (70) and adhere to a substrate (10) so as to form a coating film. If regions on the substrate to which the first vapor deposition particles and the second vapor deposition particles adhere if the vapor deposition mask is assumed not to exist are respectively denoted by a first region (92a) and a second region (92b), the limiting plate unit limits the directionalities of the first vapor deposition particles and the second vapor deposition particles in a first direction (10a) that travel to the substrate such that the second region is contained within the first region. Accordingly, it is possible to form a light emitting layer with a doping method by using vapor deposition by color.

Abstract:
A vapor deposition source (60), a limiting plate unit (80), and a vapor deposition mask (70) are disposed in this order. The limiting plate unit includes a plurality of limiting plates (81) disposed along a first direction. At least a portion of surfaces (83) defining a limiting space (82) of the limiting plate unit and surfaces (84) of the limiting plate unit opposing the vapor deposition source is constituted by at least one outer surface member (110, 120) capable of attaching to and detaching from a base portion (85). Accordingly, a vapor deposition device that is capable of forming a coating film in which edge blur is suppressed on a large-sized substrate and that has excellent maintenance performance can be obtained.
Abstract:
A coating film (90) is formed by causing vapor deposition particles (91) discharged from a vapor deposition source opening (61) of a vapor deposition source (60) to pass through a space between a plurality of control plates (81) of a control plate unit (80) and a mask opening (71) of a vapor deposition mask in this order and adhere to a substrate, while the substrate (10) is moved relative to the vapor deposition mask (70) in a state in which the substrate (10) and the vapor deposition mask (70) are spaced apart at a fixed interval. A difference in the amount of thermal expansion between the vapor deposition source and the control plate unit is detected and corrected. It is thereby possible to form, at a desired position on a large-sized substrate, the coating film in which edge blur and variations in the edge blur are suppressed.
Abstract:
A coating film (90) is formed by causing vapor deposition particles (91) to pass through a mask opening (71) of a vapor deposition mask and adhere to a substrate, the vapor deposition particles (91) being discharged from a vapor deposition source opening (61) of a vapor deposition source (60) while the substrate (10) is moved relative to the vapor deposition mask (70) in a state in which the substrate (10) and the vapor deposition mask (70) are spaced apart at a fixed interval. When a direction that is orthogonal to a normal line direction of the substrate and is orthogonal to a relative movement direction of the substrate is defined as a first direction, and the normal line direction of the substrate is defined as a second direction, a plurality of control plate columns are disposed in the first direction between the vapor deposition source opening and the vapor deposition mask, each control plate column including a plurality of control plates (80a and 80b) arranged along the second direction. With this configuration, a coating film in which blur at both edges of the coating film and variations in the blur are suppressed can be formed on a large-sized substrate.

Abstract:
A vapor deposition source (60), a plurality of limiting plates (81) and a vapor deposition mask (70) are disposed in this order. A substrate spaced apart from the vapor deposition mask at a fixed interval is moved relative to the vapor deposition mask. Vapor deposition particles (91) discharged from vapor deposition source openings (61) of the vapor deposition source pass through between neighboring limiting plates, pass through mask openings (71) formed in the vapor deposition mask, and adhere to the substrate, whereby coating films (90) are formed. The limiting plates limit the incidence angle of the vapor deposition particles that enter the mask openings, as viewed in the relative movement direction of the substrate. In this way, an organic EL element can be formed on a large-sized substrate without increasing the pixel pitch or reducing the aperture ratio.
Abstract:
An ejector comprises a body, a nozzle, a needle, a diffuser which draws in a second fluid using negative pressure caused by ejection of a first fluid from the nozzle and mixes the first and second fluids together, first and second diaphragms which allows the nozzle to shift in an axial direction with respect to the needle, and a first fluid chamber which is supplied with the first fluid. A valve in which a valve body contacts and separates from a valve seat according to the shifting action of the nozzle is formed by providing either the nozzle or the needle with the valve body and providing the other with the valve seat in the first fluid chamber. A back pressure chamber connecting to the first fluid chamber via the valve is provided between a trunk portion of the nozzle and a basal part of the needle.
