Provided is an organic light-emitting device including: a first electrode; a second electrode facing the first electrode; and an organic layer between the first electrode and the second electrode and including an emission layer, wherein the emission layer may include a host and a dopant, the host may include a first compound and a second compound different from the first compound, the dopant may include a third compound and a fourth compound different from the third compound, and the third compound may be a platinum-containing organometallic compound.

Organic light-emitting device and electronic apparatus including same

A heterocyclic compound represented by Formula 1 and an organic light-emitting device including the same are provided, wherein the substituents in Formula 1 are the same as defined in the detailed descriptions. 

Heterocyclic compound and organic light-emitting device including the same

An organic light-emitting device includes electrodes and light-emitting units that each include an emission layer; and a charge generation layer, including n- and p-type charge generation layers, disposed between each adjacent pair of light-emitting units. A wavelength of maximum intensity of light emitted from one of the light-emitting units may be different from another, an n-type charge generation layer may have a metal-containing material having a work function of about 2.0 eV to about 4.5 eV, and a p-type charge generation layer may be formed of a hole transport material, an absolute value of a HOMO energy level of the hole transport material being greater than about 5.5 eV, and an absolute value of a LUMO energy level of the hole transport material being less than that of a LUMO energy level of a hole transport layer of a light-emitting unit adjacent to the p-type charge generation layer.

Organic light-emitting device

A method of fabricating an organic light emitting device includes forming a first electrode layer on a substrate, surface-treating the first electrode layer with CFplasma, forming a first common layer containing pentacene on the surface-treated first electrode layer, forming an organic light emitting layer on the first common layer, forming a second common layer on the organic light emitting layer, and forming a second electrode layer on the second common layer. The CFplasma treatment enhances the luminous efficiency of the organic light emitting device.
