Abstract: A display apparatus includes a display panel, a back cover accommodating the display panel, and a sound output unit including at least one sound output module disposed to overlap the display panel. The at least one sound output module includes a support plate including an uneven surface and a piezoelectric element attached on the uneven surface of the support plate and has a shape corresponding to the uneven surface of the support plate. Accordingly, a sound having a straight characteristic within an audible frequency domain may be output, thereby enhancing a sense of reality and an immersion of a viewer watching an image displayed by the display apparatus.
