Abstract: The present disclosure relates to a display device comprising a display panel which outputs an image on a front surface thereof and is bendable, an exciter positioned on a rear surface of the display panel, for generating sound by vibrating the display panel, a vibration transmitting unit positioned between the exciter and the display panel, for transmitting vibrations of the exciter to the display panel, a control unit for controlling the display panel and the exciter, and a frame to which the display panel is fixed. As the display device uses the bendable display panel, such that the display panel itself can vibrate to output sound, the display device has an advantage in that there is no need to have a separate sound output device.
