Title:
ORGANIC ELECTROLUMINESCENCE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2013/042745
Kind Code:
A1
Abstract:
The present invention relates to an organic electroluminescence element comprising an organic layer (4) which includes a light emitting layer (3), between a transparent electrode (1) and a light reflecting electrode (2). A dispersal layer (5) is disposed upon the organic layer (4) which disperses light from the light emitting layer (3). Light from the light emitting layer (3) is formed as a standing wave (A) by interference. An interim location (C) of the thickness of the dispersal layer (5) is positioned in a location whereat the intensity of the standing wave (A) is 80% of the peak value thereof or greater. It is possible to increase the intensity of the light by the light being scattered at the location at the ventral curve of the standing wave, improving light extrusion.
