Title:
DINAPHTOPYLENE COMPOUND, ORGANIC EL ELEMENT USING IT, AND ORGANIC EL DISPLAY
Document Type and Number:
Japanese Patent JP3953781
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an organic EL element using a new dinaphtopylene and being excellent in the efficiency of emitting green light and emission brightness.
SOLUTION: The organic EL element has between positive and negative electrodes an organic thin film layer including a light emitting layer, the organic thin film layer containing the dinaphtopylene compound represented by the following structural formula: wherein R1 to R18 may be the same or different and each represent hydrogen atom or a substituent; at least one of R1 to R18 is preferably an aryl group, an arylamino group, or a diarylamino group; the organic thin film layer preferably has an electron transport layer or a hole transport layer containing the dinaphtopylene compound; and the light emitting layer preferably contains a host compound having a shorter light absorption wavelength than the dinaphtopylene compound and having an emission wavelength in the vicinity of the light absorption wavelength of the dinaphtopylene compound.
