7 . The display device of claim 1 , wherein the cover panel comprises at least one of a shield layer, a support layer, a cushion layer, and a light blocking layer.
8 . The display device of claim 1 , wherein:
the front portion is flat, and the corner portion has a double curved surface;
the corner portion comprises a plurality of stripe areas separated from each other; and
the plurality of stripe areas are combined to form the double curved surface of the corner portion.
9 . The display device of claim 8 , wherein:
the patterned film comprises a plurality of portions corresponding to the plurality of stripe areas; and
a first gap between adjacent stripe areas is greater than a second gap between adjacent portions of the patterned film.
10 . An electronic device comprising:
a display panel including a front portion, a side portion disposed at a side of the front portion, and a corner portion disposed at a corner of the front portion;
a patterned film attached to the display panel;
a cover panel attached to the patterned film and covering the front portion and the side portion;
a coating layer coated on the patterned film and covering the corner portion; and
an adhesive layer disposed between the cover panel and the rear surface of the patterned film,
wherein the coating layer is directly disposed on the rear surface of the patterned film.
11 . The electronic device of claim 10 , wherein:
the display panel comprises a substrate, a transistor disposed on the substrate, and a light emitting diode connected to the transistor; and
the patterned film is attached to the substrate.
12 . The electronic device of claim 10 , wherein:
the corner portion includes a double curved surface; and
the coating layer comprises a primer layer coated on a surface of the patterned film, a foam coating layer coated on a surface of the primer layer, and a hard coating layer coated on a surface of the foam coating layer.

17 . A manufacturing method of a display device, comprising:
attaching a patterned film to a display panel that includes a front portion and a corner portion disposed at a corner of the front portion;
attaching the display panel to which the patterned film is attached to a window;
attaching a cover panel to the patterned film to overlap the front portion while not overlapping the corner portion; and
forming a coating layer on a surface of the patterned film to overlap the corner portion.
18 . The manufacturing method of the display device of claim 17 , wherein forming the coating layer comprises:
forming a primer layer on the surface of the patterned film;
forming a foam coating layer on a surface of the primer layer; and
forming a hard coating layer on a surface of the foam coating layer.
19 . The manufacturing method of the display device of claim 18 , wherein the primer layer is pre-cured before forming the foam coating layer, the foam coating layer is pre-cured before forming the hard coating layer, and the primer layer and the foam coating layer are main-cured after forming the hard coating layer.
