Organic electroluminescent device and method manufacturing the same
View Patent ↗An organic electroluminescent device (OELD) and a method of manufacturing the OELD are provided. The OELD includes a substrate, an anode electrode stacked on the substrate, an organic light emitting layer that is stacked on the anode electrode and has a plurality of protrusions on the organic light emitting layer, and a cathode electrode that covers the protrusions formed on the organic light emitting layer and is formed of a metal.
1. An organic electroluminescent device (OELD) comprising:
a substrate;
an anode electrode stacked on the substrate;
an organic light emitting layer that is stacked on the anode electrode and has a plurality of protrusions on the organic light emitting layer; and
a cathode electrode that covers the protrusions formed on the organic light emitting layer and is formed of a metal.
2. The OELD of claim 1 , wherein the pitch of the protrusions is 50 to 600 nm.
3. The OELD of claim 1 , wherein the height of the protrusions is 50 to 600 nm.
4. The OELD of claim 1 , wherein the substrate is a transparent glass substrate or a plastic substrate.
5. The OELD of claim 1 , wherein the anode electrode is formed of a transparent conductive material.
6. The OELD of claim 1 , wherein the transparent conductive material comprises indium tin oxide (ITO).
