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.

Abstract: A display apparatus includes a display panel including an upper substrate and a lower substrate coupled to a rear surface of the upper substrate; a guide frame supporting the display panel, and a coupling member coupling the guide frame to the display panel. The coupling includes a main adhesive adhering the guide frame to the display panel, and a sub adhesive adhered to the guide frame adjacent to the main adhesive. Accordingly, the display panel can more readily absorb an impact applied thereto, thus enhancing the stability of the display panel.
