Disclosed is a method of producing an organic light emitting device, an organic light emitting device produced by using the method, and an apparatus used in the method. The method includes preparing a first electrode, forming one or more organic material layers on the first electrode, and forming a second electrode on the organic material layers, wherein the method includes changing functions of predetermined pattern regions of one or more layers of the organic material layers or the electrodes.

Organic light-emitting device having light-emitting pattern, method and apparatus for preparing the same

The present invention relates to a method for producing an organic light emitting device, comprising a step of sequentially forming on a substrate a first electrode formed of a metal, one or more organic material layers including a light emitting layer, and a second electrode, which comprises a step of forming a layer on the first electrode using a metal having the higher oxidation rate than the first electrode before forming the organic material layer, and to an organic light emitting device produced by the same.

Fabrication method for organic light emitting device and organic light emitting device fabricated by the same method

The present invention provides an organic light emitting device in which a layer having a refractive index in the range of 1.3 to 3 is further formed on an upper electrode of at least one region of regions through which rays having red, green, and blue colors are passed and a method of manufacturing the organic light emitting device. An optical length that can cause the microcavity effect according to the type of color of emitted light is controlled by using the layer to manufacture the organic light emitting device having high light emitting efficiency.
