Abstract
A display device includes a display panel which includes a first substrate and a light emitting element layer disposed on a first surface of the first substrate; a lower cover disposed on a second surface of the first substrate; a first sound generator disposed on the second surface of the first substrate, where the first sound generator outputs a first sound by vibrating the display panel using a magnetic force generated through a voice coil therein; and a second sound generator disposed on the second surface of the first substrate, where the second sound generator outputs a second sound corresponding to a pressure change in a space between the display panel and the lower cover caused by a vibration of the display panel.
