a liquid crystal compound; and
a liquid crystal aligning agent comprising at least one compound represented by Formula 1:

wherein in Formula 1,
X—* is C 1-20 -alkyl-*,

-L 1 -* is a single bond, *—(CH 2 ) p1 —*, *—O(CH 2 ) p1 —*, *—O—*,

*—CH═CH—*, *—C≡C—* (wherein p1 is an integer of 1 to 10), or a combination thereof;
*-L 2 -* is a single bond, *—(CH 2 ) p2 —*, *—O(CH 2 ) p2 —*, *—O—*,

*—CH═CH—*, *—C≡C—* (wherein p2 is an integer of 1 to 10), or a combination thereof;
*-L 3 -* is a single bond, *—(CH 2 ) p3 —*, *—O(CH 2 ) p3 —*, *—O—*,

*—CH═CH—*, *—C≡C—* (wherein p3 is an integer of 1 to 10), or a combination thereof;
*-L 1 -*, *-L 2 -*, and *-L 3 -* are identical to or different from one another;
*—C—* is a substituted or unsubstituted cyclic linking group selected from substituted or unsubstituted

n 1 is an integer of 1 to 3, and
n 2 and m are each independently 0 or 1.

2. The liquid crystal composition of claim 1 ,
wherein X—* is C 1-20 -alkyl-*, and
wherein the liquid crystal composition further comprises a reactive mesogen comprising at least one compound represented by Formula 2:
P1-SP1-MG-SP2-P2  Formula 2

wherein in Formula 2,
P1-* and P2-* are each independently

—SP1-* is

(wherein a is an integer of 0 to 2) and *—SP2-* is

(wherein b is an integer of 0 to 2), wherein each *-L-* is independently *—(CH 2 ) c —*, *—O(CH 2 ) c —*,

*—CH═CH—*, or *—C≡C—* (wherein c is an integer of 1 to 10), *—Z—* is *—(CH 2 ) d —* (wherein d is an integer of 0 to 12), and *—Ar—* is

(wherein each A-* is H—*, C 1-10 -alkyl-*, F—*, Br—*, I—*, *—OH, *—NH 2 , or CN—*); and
*-MG-* is

(wherein each A-* is H—*, C 1-10 -alkyl-*, F—*, Br—*, I—*, *—OH, *—NH 2 , or CN—*).

3. The liquid crystal composition of claim 2 ,
wherein the liquid crystal aligning agent comprises at least one compound represented by Formulae SA 1-1 to SA 1-8:

4. The liquid crystal composition of claim 1 ,
wherein the liquid crystal aligning agent comprises the compound represented by Formula 1,
wherein X—* is

wherein the liquid crystal composition does not include a reactive mesogen comprising at least one compound represented by Formula 2:
P1-SP1-MG-SP2-P2  Formula 2

wherein in Formula 2,
P1-* and P2-* are each independently

—SP1-* is
