    Abstract: A display device includes a display panel and a force sensor. The force sensor is disposed adjacent to a first edge of the display panel and extends along the first edge. The force sensor includes a first sensing region, a second sensing region, a first force concentration bump, and a second force concentration bump. The second sensing region is located on a side of the first sensing region and has a larger area than the first sensing region. The first force concentration bump overlaps the first sensing region. The second force concentration bump overlaps the second sensing region and is spaced apart from the first force concentration bump.
