Abstract
Official abstract text for this publication.
An organic light emitting device capable of improving the light extraction characteristics while suppressing the driving voltage and improving the luminescent performance, and a display unit using it are provided. The organic light emitting device includes: a lamination structure that includes a cathode, a plurality of layers including a light emitting layer made of an organic material, and an anode including a metal thin film in this order, in which the cathode is reflective and the anode is semi-transparent to light generated in the light emitting layer; and a resonator structure that resonates the light generated in the light emitting layer between the cathode and the anode.
First claim
Opening claim text (preview).
What is claimed is: 1 . An organic light emitting device on a substrate comprising: a lamination structure that includes, in this order, (a) a lower electrode, (b) a light emitting layer made of an organic material, (c) an upper electrode including a metal thin film, and (d) a protective layer; and a resonator structure between the lower electrode and the upper electrode configured to resonate the light generated in the light emitting layer such that the light is emitted through the upper electrode, wherein, the lower electrode comprises silver, the thickness of the lower electrode is from 30 nm to 2000 nm, the upper electrode comprises a magnesium-silver alloy, the thickness of the upper electrode is from 5 nm to 20 nm, the protective layer comprises silicon oxide or silicon nitride, and the thickness of the protective layer is from 500 nm to 10000 nm.
