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.

Abstract translation: 显示装置包括：显示面板，包括上基板和与下基板的后表面连接的下基板; 支撑显示面板的引导框架和将引导框架连接到显示面板的联接构件。 联接器包括将引导框架粘附到显示面板的主粘合剂，以及粘附到与主粘合剂相邻的引导框架上的副粘合剂。 因此，显示面板可以更容易地吸收施加到其上的冲击，从而提高显示面板的稳定性。
