Abstract: A display apparatus includes a display module displaying an image, a rear structure supporting the display module, a vibration generating device vibrating the display module, and a stiff member disposed on a rear surface of the display module. Accordingly, a sound pressure level corresponding to a high frequency domain is prevented from being reduced, thereby enhancing the quality of a sound output to a region in front of a display panel.
