Abstract: A display device includes a display panel including a first non-folding area, a second non-folding area, and a folding area that are arranged along a first direction, the folding area being foldable along a folding line extending along a second direction intersecting the first direction, a panel lower member disposed below the display panel, and a digitizer disposed below the panel lower member and including a base layer and sensing coils. The base layer includes a folding portion including holes overlapping the folding area of the display panel and first and second non-folding portions disposed along the first direction. The folding portion is disposed between the first and second non-folding portions. The sensing coils are disposed on the base layer, and the base layer includes a matrix including a filler and an elastomer and weaving-shaped fiber lines disposed inside the matrix and alternately arranged with each other.
