Abstract: A display device includes a display panel with a folding area between two non-folding areas. A window is on the display panel. A first adhesive layer is between the window and the display panel, and has a first thickness. A lower structure is under the display panel. The lower structure includes a first support layer overlapping the first non-folding area and the second-non-folding area, a digitizer under the first support layer, including a loop coil, and overlapping the first non-folding area and the second non-folding area, an electromagnetic shielding layer under the digitizer having a second thickness, a metal layer under the electromagnetic shielding layer, and an insulating second support layer under the metal layer. The first thickness is about 75 μm to about 100 μm, and the second thickness is about 30 μm to about 60 μm.
