Abstract: A display device includes a display panel including a first non-folding region, a second non-folding region, and a folding region interposed between the first non-folding region and the second non-folding region, and a digitizer disposed under the display panel and divided into an active region and a non-active region surrounding the active region. The digitizer includes a first sensing coil disposed in the active region, a first compensating layer disposed on the first sensing coil to cover the first sensing coil, a second sensing coil disposed under the first sensing coil in the active region, a bridge line disposed under the second sensing coil, and a second compensating layer disposed under the bridge line to cover the bridge line. A surface of the first compensating layer, which is opposite to a surface of the first compensating layer covering the first sensing coil, is flat.

Abstract: A display device includes: a display panel including a first non-folding area, a folding area, and a second non-folding area along a first direction; and a digitizer under the display panel, and having an active area and a non-active area around the active area, the digitizer including: a first sensing coil in the active area; a second sensing coil in the active area, and overlapping with the folding area; a third sensing coil under the first sensing coil, and overlapping with the second non-folding area; and a fourth sensing coil under the third sensing coil, and overlapping with the first non-folding area. The third sensing coil and the fourth sensing coil do not overlap with each other in a plan view.
