Abstract
Official abstract text for this publication.
A method of manufacturing an organic light-emitting diode including preparing, by a dry etching method using a particle single layer film as an etching mask, a substrate provided with an uneven structure in which a plurality of unevenness is arranged in two dimensions on the surface of the substrate, and stacking, on the uneven structure, at least an anode conductive layer, an EL layer including a light-emitting layer containing an organic light-emitting material, and a cathode conductive layer containing a metal layer, such that the uneven structure is reproduced on the surface of the metal layer on the side of the EL layer, wherein the particle single layer film is formed using a mixture of a plurality of particles having different particle sizes, and an uneven structure is provided which satisfies particular requirements.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of manufacturing an organic light-emitting diode, comprising: preparing a substrate provided with an uneven structure in which a plurality of concave portions or convex portions are arranged in two dimensions on a surface of the substrate using a dry etching method in which a particle single layer film is used as an etching mask; and depositing at least an anode conductive layer, an electroluminescent layer comprising a light-emitting layer…
