Abstract
An organic electroluminescent element comprising: an organic laminate comprising at least an light emission layer formed via a wet process, the light emission layer comprising a host material and a guest material; and a pair of electrodes, wherein a solvent used for forming the light emission layer has a boiling point of 105° C. or less and a saturation vapor pressure at 20° C. of 20 mmHg or more, and a method of manufacturing the organic electroluminescent element
Claims20
An organic electroluminescent element comprising:
- an organic laminate comprising at least an light emission layer formed via a wet process, the light emission layer comprising a host material and a guest material;
- and
- a pair of electrodes,
- wherein a solvent used for forming the light emission layer has a boiling point of 105° C. or less and a saturation vapor pressure at 20° C. of 20 mmHg or more.
A method of manufacturing an organic electroluminescent element comprising,
- (I) the steps of
- forming an anode on a substrate;
- forming an organic laminate on the anode;
- and
- forming a cathode on the organic laminate, or
- (II) the steps of
- forming a cathode on a substrate;
- forming an organic laminate on the cathode;
- and
- forming an anode on the organic laminate,
- wherein the step of forming the organic laminate comprises at least a step of forming a light emission layer via a wet process, the light emission layer comprising a host material and a guest material;
- wherein a solvent used for forming the light emission layer has a boiling point of 105° C. or less and a saturation vapor pressure at 20° C. of 20 mmHg or more.
