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 a 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 electroluminescence (EL) display panel includes pixels arranged in a matrix of rows and columns, and includes: a substrate; pixel electrode layers that are arranged on the substrate in the matrix; an insulating layer that is provided above the substrate and the pixel electrode layers, and has elongated openings and a grooved portion for each of the pixels, the openings extending in a column direction and being arranged in a row direction, the grooved portion having an upper opening and a bottom and being communicated with at least one of the openings in plan view; organic functional layers that are provided above the pixel electrode layers, and include light emitting layers in which organic electroluminescence occurs in the openings; and a light-transmissive counter electrode layer that is provided above the organic functional layers. Cross-sectional profiles of the openings taken along the row direction are uniform in the column direction.

Abstract: Pixels include red sub-pixels, green sub-pixels, first blue sub-pixels that emit dark blue light, and second blue sub-pixels that emit light blue light. Above a substrate, first blue pixel electrodes and first blue organic light-emitting layers are layered in regions of the first blue sub-pixels and second blue pixel electrodes and second blue organic light-emitting layers are layered in regions of the second blue sub-pixels. The first blue light-emitting layers and the second blue light-emitting layers are made from the same material. In a direction perpendicular to a top plane of the substrate, a distance between top surfaces of the first blue organic light-emitting layers and top surfaces of the first blue pixel electrodes is less than a distance between top surfaces of the second blue organic light-emitting layers and the surfaces of the second blue pixel electrodes.
