Claims (10)

1. A display device, comprising:

a display panel that is foldable with respect to a folding axis and includes a display area and a peripheral area surrounding the display area, the display area including a plurality of pixels to generate an image;

a digitizer disposed under the display panel part and entirely overlapping the display area to sense a coordinate of an input member on the display area by using electromagnetic resonance, the digitizer having a lower surface, which includes a recess when the display device is in an unfolded state;

a magnetic member having a plate shape that entirely overlaps the digitizer and being disposed under the digitizer such that the digitizer is disposed between the display panel and the magnetic member; and

a support structure disposed under the digitizer such that the digitizer is disposed between the display panel and the support structure, wherein the digitizer has a first thickness within the recess that is less than a second thickness beyond the recess, when the display device is in the unfolded state, when the display device is in the unfolded state, and wherein a portion of the support structure is disposed within the recess.

2. The display device of claim 1 , wherein the support structure is porous.

3. The display device of claim 1 , wherein the support structure includes a polymeric material.

4. The display device of claim 1 , wherein the support structure directly contacts the magnetic member.
