Abstract: A display device includes a display panel and a touch panel. The touch panel calculates coordinate information of an input position by an electrostatic capacitive method in a first mode and calculates the coordinate information of the input position by an electromagnetic induction method in a second mode. The touch panel includes scan line groups and source line groups, which are operated as touch electrodes or touch coils on the basis of the operating mode thereof. In addition, the touch panel includes touch electrodes and touch coils, which are individually operated on the basis of the operating mode thereof.

Abstract: A display device includes a display substrate comprising a polymer layer including a first non-bending area, a second non-bending area that overlaps the first non-bending area when viewed in a plan view, and a bending area arranged between the first non-bending area and the second non-bending area. A display element layer is disposed on the polymer layer. A plurality of signal pad groups is disposed in the second non-bending area and is configured to be electrically connected to the display element layer. An upper substrate is disposed on a top surface of the display substrate. A flexible circuit board comprising a plurality of connection pad groups is arranged in correspondence to the signal pad groups. An area of the upper substrate is larger than an area of the display substrate when viewed in a plan view.
