Abstract
A display device includes: a display panel including a first substrate and a light emitting element layer disposed on the first substrate; and a sound generator disposed on one surface of the first substrate, where the sound generator vibrates the display panel to output a sound. The sound generator includes: a first vibration generator which vibrates the display panel by generating a magnetic force using a first voice coil therein; and a second vibration generator including a vibration layer which contracts or expands based on a voltage applied thereto to vibrate the display panel, where the first vibration generator and the second vibration generator overlap each other in a thickness direction of the display panel.
