support patterns disposed on the spacer bonding layer, the support patterns being spaced apart from each other; and
the at least one separation region comprises a spacing space between adjacent support patterns among the support patterns.
15. The protection film of claim 14 , wherein:
a shape of the spacer extends in a first direction on a plane; and
a shape of the spacing space extends in a second direction intersecting the first direction.
16. A window, comprising:
a window substrate; and
a first protection film disposed on a surface of the window substrate,
wherein the first protection film comprises:
a first film layer; and
a spacer disposed on a surface of the first film layer, the spacer comprising at least one separation region formed in a thickness direction from a surface of the spacer.
17. The window of claim 16 , wherein the spacer comprises:
a spacer bonding layer disposed on the surface of the first film layer; and
a support layer disposed on the spacer bonding layer.
18. The window of claim 17 , wherein:
the at least one separation region comprises a cutting pattern; and
the cutting pattern is formed in the thickness direction from a surface of the support layer.
19. The window of claim 18 , wherein the cutting pattern completely extends through the support layer in the thickness direction.
20. The window of claim 19 , wherein the cutting pattern extends to an interior region of the spacer bonding layer.
21. The window of claim 18 , wherein:
a shape of the spacer extends in a first direction on a plane; and
a shape of the cutting pattern extends in a second direction intersecting the first direction.
22. The window of claim 21 , further comprising:
a mounting component protruding in the thickness direction from the surface of the window substrate,
wherein, with respect to the surface of the window substrate, a height of a surface of the mounting component is higher than a height of the surface of the first film layer and lower than a height of the surface of the spacer.
23. The window of claim 16 , wherein:
the spacer comprises:
a spacer bonding layer disposed on the surface of the first film layer; and
support patterns disposed on the spacer bonding layer, the support patterns being spaced apart from each other; and
the at least one separation region comprises a spacing space between adjacent support patterns among the support patterns.
24. The window of claim 23 , wherein:
a shape of the spacer extends in a first direction on a plane; and
a shape of the spacing space extends in a second direction intersecting the first direction.
