the first area is provided closer to the substrate than the second area, and the first area comprises a hard coating component, and the second area comprises an anti-fingerprint component.

3 . The window of claim 2 , wherein the hard coating component comprises at least one of the first compound and a derivative of the first compound, and
the anti-fingerprint component comprises at least one of the second compound and a derivative of the second compound.

4 . The window of claim 2 , wherein a thickness of the second area is thinner than a thickness of the first area.

5 . The window of claim 1 , wherein in Chemical Formula 1-a and Chemical formula 1-b, R 5 is one selected from the group consisting of a methylene group, an ethylene group, a propylene group, an isopropylene group, an n-butylene group, an s-butylene group, an isobutylene group, a t-butylene group, an n-pentylene group, an n-hexylene group, an n-heptylene group, and an n-octylene group.
