1. An electronic device, comprising:
a display panel, which provides an image; and
a digitizer below the display panel and including a first non-folding part and a second non-folding part, which are arranged along a first direction, and a folding part between the first non-folding part and the second non-folding part, wherein the folding part is foldable with respect to a folding axis extending along a second direction intersecting the first direction,
wherein the folding part includes first group holes each including holes arranged along the second direction, and second group holes between neighboring first group holes of the first group holes and each including holes arranged along the second direction,
wherein the digitizer includes:
a base layer;
first loop coils on the base layer and each including a first part on the first non-folding part, a second part on the second non-folding part, and a third part on the folding part, wherein the third part surrounds a portion of corresponding holes of the first and second group holes; and
second loop coils insulated from the first loop coils and below the base layer,
wherein each of the holes of the first and second group holes extends in the second direction and includes a first end and a second end that are spaced apart from each other in the second direction,
wherein the third part includes:
first patterns adjacent to the first ends of corresponding holes of the first and second group holes;
second patterns adjacent to the second ends of corresponding holes of the first and second group holes; and
third patterns that connect corresponding first patterns to corresponding second patterns,
wherein each of the first patterns and the second patterns has a curvature.
