Abstract
Official abstract text for this publication.
An organic light-emitting panel includes a reflective electrode, a functional layer, having a single or multi-layer structure, located on the reflective electrode, an organic light-emitting layer located on the functional layer, a transparent electrode located above the organic light-emitting layer, a low refractive index layer located on the transparent electrode, and a first thin-film sealing layer located on the low refractive index layer. The low refractive index layer has a lower refractive index than both the transparent electrode and the first thin-film sealing layer. Difference between respective refractive indices of the low refractive index layer and the transparent electrode is 0.4-1.1. Difference between respective refractive indices of the low refractive index layer and the first thin-film sealing layer is 0.1-0.8. The low refractive index layer has thickness of 20-130 nm.
First claim
Opening claim text (preview).
The invention claimed is: 1. An organic light-emitting panel, comprising: a first electrode that is light-reflecting; a functional layer having a single layer or multi-layer structure, located on the first electrode; an organic light-emitting layer located on the functional layer, the organic light-emitting layer including a red organic light-emitting layer portion defining a red organic light-emitting element, a green organic light-emitting layer portion defining a green orga…
