Title:
Electronic device
Document Type and Number:
Japanese Patent JP5987885
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a thiadiazole compound, a compound for light-emitting elements, and a light-emitting element capable of emitting light in the near-infrared region and having high efficiency and long life, and a light-emitting device, an authentication device, and an electronic device having the light-emitting element.SOLUTION: A light-emitting element 1 comprises an anode 3, a cathode 9, and a light-emitting layer 6 provided between the anode 3 and the cathode 9. The light-emitting layer 6 is configured to contain a compound represented by formula (1) and a compound represented by formula IRH-1. In the formula (1), A and B each represent an aryl group, an arylamino group or triarylamine. In the formula IRH-1, n represents a natural number of 1 to 12; and each R is a substituent or a functional group, and represents an aryl group or an arylamino group which may have H, an alkyl group or a substituent.
