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 holeof 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&#x2212;1)-th thin film forming nozzle hole array Q. 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.

Thin film production method and organic el device production method

A decorative sheet is caused to emit light from part of the front surface to improve the design features. A decorative sheetaccording to an embodiment includes a first refractive index layer (high refractive index layer)having a first refractive index, a decorative layer, a second refractive index layer (low refractive index resin layer)that has a second refractive index lower than the first refractive index and is provided between the first refractive index layer and the decorative layer, and a light diffusion layerthat is provided in partial contact with one surface of the first refractive index layer and diffuses light entering from the first refractive index layer so that light is released from part of the front surface of the decorative sheet. A resin molded bodymay be integrally laminated on the back surface side of the decorative sheetto form a decorative molded article. In addition, the decorative molded articlemay be provided with a light sourcethat injects light from the side surface of the decorative sheetto form a decorative module
