Light emitting device and electronic apparatus including the same

Disclosed are a light emitting device and an electronic apparatus including the same. The light emitting device comprises: a first electrode; a second electrode which faces the first electrode; and a middle layer which includes: a light emitting layer which is arranged between the first electrode and the second electrode, a hole transporting layer which is arranged between the first electrode and the light emitting layer, and an electron transporting area which is arranged between the light emitting layer and the second electrode. The first electrode and the hole transporting layer are in direct contact with each other. The first electrode has a multi-layered structure in which first to m^th (m is an integer of 3 or more) layers are sequentially stacked. The m^th layer is composed of a single material selected from GeO_2, MoO_3, and WO_x (2.1
