Definitions
- the present specification relates to an organic light emitting device.
- the organic light-emitting device has a structure in which an organic thin film is disposed between two electrodes.
- a voltage is applied to the organic light emitting device having such a structure, electrons and electrons injected from the two electrodes are combined in the organic thin film to form a pair and then emit light while disappearing.
- the organic thin film may be composed of a single layer or multiple layers as necessary.
- Materials used in organic light-emitting devices are pure organic materials or complex compounds in which organic materials and metals form a complex, and depending on the use, hole injection materials, hole transport materials, light-emitting materials, electron transport materials, electron injection materials, etc. It can be classified as Here, as the hole injection material or the hole transport material, an organic material having a p-type property, that is, an organic material that is easily oxidized and has an electrochemically stable state during oxidation is mainly used. Meanwhile, as an electron injection material or an electron transport material, an organic material having an n-type property, that is, an organic material that is easily reduced and has an electrochemically stable state upon reduction is mainly used.
- the light-emitting layer material a material having both p-type and n-type properties, that is, a material that is stable in both oxidation and reduction states, is preferable, and excitons generated by recombination of holes and electrons in the emission layer are formed.
- a material having high luminous efficiency that converts it to light when it is formed is preferable.
