1. A display device that is foldable with respect to a folding axis, comprising:
a display panel part that is foldable, the display panel part generating an image of the display device;
a digitizer disposed under the display panel part and sensing a coordinate of an input member by using electromagnetic resonance;
a first magnetic member configured to induce electromagnetic resonance with the input member and disposed under the digitizer so that the digitizer is disposed between the display panel part generating the image and the first magnetic member, the first magnetic member including a first portion and a second portion, the first portion and the second portion being disposed on a common plane and spaced apart from each other by a dividing area extending along the folding axis in an unfolded state of the display device; and
a second magnetic member disposed under the first magnetic member and including a first portion and a second portion,
wherein a distance between the first portion and the second portion of the second magnetic member is smaller than a distance of the first portion and the second portion of the first magnetic member such that the second magnetic member at least partially overlaps the dividing area.
