a and c are each an integer of 0 to 6, b is an integer of 0 to 5, and d is an integer of 0 to 7,
L 1 is a single bond, or a C 6 -C 12 arylene group;
Ar 1 is an C 6 -C 12 aryl group;
wherein the aryl group and arylene group may be substituted with one or more substituents selected from the group consisting of deuterium, a C 6 -C 20 aryl group, and a C 6 -C 20 aryl group substituted with deuterium, and hydrogen of these substituents may be further substituted with one or more deuterium.

2. The compound according to claim 1 , wherein Ar 1 is represented by any one of Formulas (A-1) to (A-6):

wherein:
1) R 5 , R 6 , R 7 and R 8 are each the same or different and independently hydrogen or deuterium,
2) e is an integer of 0 to 5, f is an integer of 0 to 7, g is an integer of 0 to 4, h is an integer of 0 to 5, and
3) * indicates a position to be bonded.

3. The compound according to claim 1 , wherein L 1 is represented by a single bond or any one of Formulas <L-1> to <L-19>:

wherein:
R 10 , R 11 , R 12 and R 13 are each the same or different from each other and are independently hydrogen or deuterium;
j, l and m are each independently an integer of 0 to 4, k is an integer of 0 to 6, and
* indicates a position to be bonded.

4. The compound according to claim 1 , wherein the compound represented by Formula 1 comprises at least one deuterium.
