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.

Abstract: An organic EL element includes an anode, a light emitting layer, a functional layer, a cathode, and a low refractive index layer. The light emitting layer is disposed above the anode. The functional layer is disposed on and in contact with the light emitting layer and includes a first metal. The cathode is disposed on and in contact with the functional layer and is made of a light transmissive metal oxide. The low refractive index layer is disposed on and in contact with the cathode. Refractive index of the low refractive index layer is smaller than refractive index of the cathode, film thickness of the functional layer is from 15 nm to 35 nm, and a distance between an anode-side surface of the light emitting layer and an interface between the cathode and the low refractive index layer is 110 nm or greater.
