Abstract

A light emitting element includes a light emitting layer that is provided between an anode, a cathode, an anode, and a cathode, and the light emitting layer is configured to include the compound represented by Formula 1 below and the compound represented by Formula RH-1 below. (In Formula 1, A indicates an aryl group, an arylamino group, or triarylamine that may respectively independently include a hydrogen atom, an alkyl group, and a substituent.) (In Formula IRH-1, n indicates a natural number between 1 and 12, and R represents a substituent or a functional group, and indicates an aryl group or an arylamino group that may respectively independently include a hydrogen atom, an alkyl group, and a substituent.)

Claims (34)

1. A thiadiazole-based compound represented by Formula 1 below:

where in Formula 1, A indicates an aryl group, a diarylamino group, or triarylamine that may respectively independently include a hydrogen atom, an alkyl group, and a substituent.

2. A light emitting element compound comprising the thiadiazole-based compound according to claim 1 .

3. A light emitting element comprising:

an anode;

a cathode; and

a light emitting layer that is provided between the anode and the cathode and that emits light through a passage of an electric current between the anode and the cathode,

wherein the light emitting element includes a host material and a compound represented by Formula 1 below as a light emitting material:

where in Formula 1, A indicates an aryl group, an arylamino group, or triarylamine that may respectively independently include a hydrogen atom, an alkyl group, and a substituent.

4. The light emitting element according to claim 3 , wherein the light emitting layer includes a compound represented by Formula IRH-1 below as the host material:

where in Formula IRH-1,

n indicates a natural number between 1 and 12, and

R represents a substituent or a functional group, and indicates an aryl group or an arylamino group that may respectively independently include a hydrogen atom, an alkyl group, and a substituent.

5. The light emitting element according to claim 3 , wherein the light emitting layer includes a compound represented by Formula IRH-2 below as the host material:

where in Formula IRH-2,

R 1 to R 4 indicate aryl groups or arylamino groups that may respectively independently include a hydrogen atom, an alkyl group, and a substituent, and

R 1 to R 4 may be the same as or different from one another.

6. The light emitting element according to claim 3 wherein the light emitting element includes a compound represented by Formula IRH-3 below as the host material:

where in Formula IRH-3,

R 1 and R 2 indicate aryl groups or arylamino groups that may respectively independently include a hydrogen atom, an alkyl group, and a substituent, and

R 1 and R 2 may be the same as or different from one another.

7. The light emitting element according to claim 3 , wherein the host material consists of carbon atoms and hydrogen atoms.

8. A light emitting device comprising the light emitting element according to claim 3 .

9. A light emitting device comprising the light emitting element according to claim 4 .

10. A light emitting device comprising the light emitting element according to claim 5 .

11. A light emitting device comprising the light emitting element according to claim 6 .

12. An authentication device comprising the light emitting element according to claim 3 .

13. An authentication device comprising the light emitting element according to claim 4 .

14. An authentication device comprising the light emitting element according to claim 5 .

15. An authentication device comprising the light emitting element according to claim 6 .

16. An electronic apparatus comprising the light emitting element according to claim 3 .

17. An electronic apparatus comprising the light emitting element according to claim 4 .

18. An electronic apparatus comprising the light emitting element according to claim 5 .
