Abstract: A display device that includes a display panel having a first substrate, a second substrate, and a light-emitting element layer. The light emitting layer is disposed between the first and second substrates and is configured to emit light in a direction toward the second substrate. A first sound generator is disposed on a first surface of the first substrate and is configured to vibrate the display panel to output a first sound. A first heat dissipation film is disposed between the first substrate and the first sound generator.

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.
