Composite electrode for light-emitting device
First Claim
1. A multi-layer composite electrode for a light-emitting device, comprising:
- a transparent, conductive layer;
a reflective, conductive layer in electrical and physical contact wit the transparent, conductive layer; and
a light-scattering layer formed between the transparent, conductive layer and the reflective, conductive layer over only a first portion of the transparent, conductive layer, wherein the light-scattering layer is relatively less conductive than the reflective, conductive layer and the reflective, conductive layer is in electrical contact with the transparent, conductive layer over a second portion of the transparent, conductive layer where the light-scattering layer is not formed.

Abstract
A multi-layer composite electrode for a light-emitting device, comprising: a transparent, conductive layer; a reflective, conductive layer in electrical contact with the transparent, conductive layer; and a light-scattering layer formed between the transparent, conductive layer and the reflective, conductive layer over only a first portion of the transparent, conductive layer, wherein the light-scattering layer is relatively less conductive than the reflective, conductive layer and the reflective, conductive layer is in electrical contact with the transparent, conductive layer over a second portion of the transparent, conductive layer where the light-scattering layer is not formed. Also disclosed is a method of making such a multi-layer composite electrode in a light emitting device, and an organic light-emitting diode (OLED) device comprising such a composite electrode.
