Title:
LIGHT-EMITTING LAYER MANUFACTURING METHOD, LIGHT-EMITTING LAYER, AND ORGANIC LIGHT-EMITTING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2015/118936
Kind Code:
A1
Abstract:
When a light-emitting layer that contains host molecules and guest molecules is deposited on a substrate by vapor phase deposition, the temperature of the substrate is set to a temperature no greater than the surface glass transition temperature of the guest molecules. By this means, it is possible to manufacture a light-emitting layer with which a high light extraction efficiency may be obtained.
