    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.
