Abstract: The present embodiment relates to a double-faced display device generating sound by directly vibrating a display panel and includes: a first display panel and a second display panel disposed at the front and rear surface thereof, respectively; a single sound generating actuator connected to the first display panel and the second display panel to simultaneously vibrate the first display panel and the second display panel and thus generate sound; and a support part configured to support the sound generating actuator, the first display panel, and the second display panel. The present embodiment does not require a separate speaker and thus can achieve a thin or slim display device, and can improve the localization or the quality of sound output in opposite directions in the double-faced display device.
