Title: LIGHT EMITTING DEVICE
Abstract:
An organic layer (120) is positioned between a first electrode (110) and a second electrode (130), and has a first light emitting layer (123) and a first Cs-containing layer (124). The first Cs-containing layer (124) is positioned between the first light emitting layer (123) and the second electrode (130). The first Cs-containing layer (124) is an electron transport layer and/or an electron-injection layer, and is an organic layer containing Cs (cesium). The Cs peak concentration in the first Cs-containing layer (124) is 0.07-0.20 % in atomic percentage.
