Abstract: A display device includes a display panel and a first force sensor. The first force sensor is disposed adjacent to a first edge of the display panel and extends along the first edge. The first force sensor includes a plurality of first sensing regions and a second sensing region. disposed closer to the second end of the first force sensor than the first sensing regions. The first sensing regions are disposed closer to a first end of the first force sensor than the second sensing region, and the second sensing region. The second sensing region is disposed closer to a second end of the first force sensor than the first sensing regions. The second sensing region has a larger area than each of the first sensing regions.
