Abstract
Organic light-emitting device manufacturing method performed by using a manufacturing apparatus placed where light from outside is blocked and a lighting device emitting light constituted of light components with wavelengths of 500 nm or longer is placed. The manufacturing apparatus includes a main body having an ejector ejecting ink containing organic light-emitting material and a light-transmissive tube forming at least part of a transport path connecting a tank containing the ink and the ejector. The method includes: removing the ink inside the transport path when a total exposure amount ET (lux×hours) satisfies ET≥α×17500 where α is a constant satisfying α≥1. ET is a product of E denoting light amount (lux) from the lighting device to which the tube is exposed and T denoting time amount (hours) over which the tube is exposed to the light from the lighting device.
