Organic light emitting device and display unit

摘要

An organic light emitting device capable of improving the light extraction characteristics while suppressing the driving voltage and improving the luminescent performance, and a display unit using it are provided. The organic light emitting device includes: a lamination structure that includes a cathode, a plurality of layers including a light emitting layer made of an organic material, and an anode including a metal thin film in this order, in which the cathode is reflective and the anode is semi-transparent to light generated in the light emitting layer; and a resonator structure that resonates the light generated in the light emitting layer between the cathode and the anode.
