Abstract
A haptic actuator and a display device including the same are provided. The haptic actuator includes a reinforcing component where a supporter extends downwardly from a long side of a body with a rectangular plane shape arranged on a piezoelectric element. A cavity is positioned along the relatively long side of the reinforcing component. Vibrations generated in the piezoelectric element can be transferred efficiently to the cavity positioned along the long side of the reinforcing component.
