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.
