    Abstract: An electronic device includes: a display panel and a digitizer including first and second non-folding parts and a folding part between the first and second non-folding parts. 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, second loop coils below the base layer. The third part includes first patterns adjacent to first ends of first group holes, second patterns adjacent to second ends of second group holes, and third patterns connecting the first and second patterns. Each of the first and second patterns has a curvature.
