Abstract

The invention relates to a light-emitting device, an electronic equipment and a process of producing the light-emitting device. The invention is to provide a cathode having both a high electrical conductivity and a high transparency and the light-emitting device having the cathode. The light-emitting device (D1) includes a substrate, a light-reflecting layer (14) formed on the substrate (10), a first electrode (16) disposed on or above the light-reflecting layer (14), a light-emitting function layer (18) disposed on the first electrode (16), and an electron-injection layer (49) disposed on the light-emitting function layer (18) and a second electrode (20) formed on the electron-injection layer (49) having a second electrode (20) with a semi-transparent reflectivity. The second electrode is made of an Ag alloy having an Ag content of from 50% by atoms to 98% by atoms.

Description

technical field

[0001] The present invention relates to a light emitting device, an electronic device, and a method for manufacturing the light emitting device. Background technique

[0002] Various light-emitting devices using light-emitting elements such as Organic Light Emitting Diode (Organic Light Emitting Diode, hereinafter referred to as "OLED") elements called organic EL (Electroluminescent) elements or light-emitting polymer elements have been proposed in recent years. A light-emitting element used in such a light-emitting device generally has a structure in which a light-emitting layer formed of an organic EL material or the like is sandwiched between two electrodes.

[0003] For example, Patent Document 1 discloses a light-emitting element comprising an anode, an organic light-emitting medium formed on the anode, and a cathode formed on the organic light-emitting medium. In Patent Document 1, the region in contact with the anode in the organic luminescent medium ...
