Abstract: A force sensor includes first and second substrates. The second substrate faces the first substrate. A driving electrode is disposed on a first surface of the first substrate facing the second substrate. A sensing electrode is disposed on the first surface of the first substrate and is spaced apart from the driving electrode. A force sensitive layer is disposed on a first surface of the second substrate, facing the first substrate. The driving electrode includes a main driving protrusion that protrudes from a side surface of the driving electrode, facing the sensing electrode.

Abstract: A display device includes a display panel that includes an upper surface, a first side surface portion that extends from a first side of the upper surface, and a second side surface portion that extends from a second side connected to the first side, a first force sensor disposed in the first side surface portion and a second force sensor disposed in the second side surface portion, and a controller that determines a type and a state of an application being executed when a first input signal is sensed through the first force sensor and execute an operation corresponding to the type of the application and the state of the application being executed when a second input signal is sensed through the second force sensor within a preset time from an interruption of the first input signal.
