Abstract
A method for manufacturing an organic EL display panel through a printing process of applying, to a board in a first orientation, a raw material liquid for forming at least one of light-emission contribution layers including a light-emission layer, the first orientation being an orientation of the board in which a printing surface faces upward and is held in a horizontal direction. The method includes: a wet cleaning process of cleaning the board; and a first rotation process of rotating the board from a second orientation to the first orientation after the wet cleaning process, the second orientation being an orientation of the board in which the printing surface is tilted at an angle with respect to the printing surface in the first orientation, the angle being selected from a range from 90 to 270 degrees inclusive. The printing process is performed after the first rotation process.
