Title:
METHOD OF MANUFACTURING ORGANIC EL DISPLAY PANEL AND INK DRYING DEVICE
Document Type and Number:
Japanese Patent JP2018078094
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce luminance unevenness by equalizing film thickness of a light emitting layer 123.SOLUTION: A method of manufacturing an organic light-emitting panel includes the steps of: applying ink containing an organic light-emitting material to each of gaps 522z between column banks 522Y adjacent in a row direction so that the ink is continuous in the column direction between ends of the column banks 522Y in the column direction; arranging a substrate 100x with the ink applied thereon and a rectifying plate 400 to face each other such that a plurality of through holes 400a are positioned at least in a region 10a where the through holes face the column banks 522Y on the substrate 100x, while the rectifying plate 400 where the through holes are formed in a uniform density is at a predetermined distance from the column banks; exhausting gas from an environment including the substrate 100x and the rectifying plate 400; and heating the substrate 100x to dry the ink in a state where atmospheric pressure is equal to or less than a predetermined pressure.SELECTED DRAWING: Figure 5
