Abstract: A method for manufacturing an electronic device according to one embodiment includes forming a first electrode layer, forming a device functional portion, and forming a second electrode layer. At least one of the first electrode layer, one or a plurality of functional layers of the device functional portion, and the second electrode layer is formed by coating a base substrate containing a substrate with ink containing a material of the at least one layer from an inkjet printing device 24. The inkjet printing device includes an ink supply unit 30, an inkjet head 28, a flow path 38 of the ink, a drive unit 40, and a diaphragm type pressure adjusting mechanism 42 which is arranged between the drive unit and the inkjet head on the flow path. The ink satisfies at least one of a surface tension of 15 mN/m to 25 mN/m and a specific gravity of 1.5 or more.

Abstract: A method for manufacturing an organic EL panel capable of reducing uneven emission luminance (uneven light emission) is disclosed. A method for manufacturing an organic EL panel according to an embodiment of the invention is a method for manufacturing an organic EL panel including a functional layer including at least a light emitting layer containing an organic material, including a coating step of forming a functional layer by horizontally conveying a base material (110) having flexibility using a roll-to-roll process and coating a coating solution containing an organic material onto the base material (110) using an inkjet applicator (30) disposed above the base material (110), wherein in the coating step, the base material (110) is floated by air using an air floating stage (20) disposed below the base material (110) and the coating solution is coated onto the base material (110).

Abstract: A thin film production method according to one embodiment includes: a coating film forming step of forming a coating film by discharging a coating liquid on a support from first to M-th line heads (M is 2 or larger and N or smaller) while allowing the support to pass through N line heads once; and a drying step of obtaining a thin film by drying the coating film. A thin film forming nozzle hole 28 of the m-th line head (m is 2 or larger and M or smaller) is arranged to be positioned between adjacent thin film forming nozzle holes in an (m?1)-th thin film forming nozzle hole array Qm-1. Every time the first line head discharges the coating liquid, the m-th line head applies the coating liquid onto the support at a predetermined delay time with respect to a discharge time of the first line head. The first to M-th line heads discharge the coating liquid from the film forming nozzle hole selected in accordance with a shape of a thin film formation region onto the support.
