Abstract
A light-emitting device includes a light-reflecting layer, a first electrode disposed on or above the light-reflecting layer, a semi-transparent reflective second electrode, a light-emitting function layer disposed between the first electrode and the second electrode, and an electron-injection layer disposed between the light-emitting function layer and the second electrode. The second electrode is made of an Ag alloy having an Ag content of from 50% by atoms to 98% by atoms.
Claims3
A method for manufacturing a light-emitting device, the method comprising:
- forming a light-reflecting layer disposed above a substrate;
- forming a first electrode disposed on or above the light-reflecting layer;
- forming a light-emitting function layer disposed on or above the first electrode;
- forming an electron-injection layer disposed on the light-emitting function layer;
- and
- forming a second electrode on the electron-injection layer,
- wherein the forming the second electrode is performed by co-depositing Mg and Ag at a deposition rate ratio of Mg to Ag in the range of 1:20 to 1:50.
