Abstract

Official abstract text for this publication.

An organic electroluminescent (EL) display includes a plurality of organic EL devices for red, green, and blue subpixels, each including a first electrode on a light output side, a second electrode opposite the first electrode, and an organic compound layer including a light-emitting layer therebetween. The organic EL devices have a resonator structure between a first reflective surface closer to the first electrode than the organic compound layer and a second reflective surface closer to the second electrode than the organic compound layer. A predetermined white color is displayed by mixing the three colors such that an optical distance of the organic EL devices of each color between an emission position in the light-emitting layer and the second reflective surface is set within ±10% from an optical distance corresponding to an nth-order minimum of a curve of required current density against at least the optical distance.

First claim

Opening claim text (preview).

What is claimed is: 1. An organic electroluminescent apparatus comprising: an organic EL element emitting light of red color, an organic EL element emitting light of green color and an organic EL element emitting light of blue color, wherein each of the organic EL elements includes a first electrode on a light output side, a second electrode opposite the first electrode, and an organic compound layer including a light-emitting layer between the first electrode and the second ele…
