The cover member790may be formed on the touch panel780. For example, the adhesive layer760may be disposed between the touch panel780and the cover member. According to an exemplary embodiment, the adhesive layer may be omitted between the touch panel780and the cover member790.

In the display apparatus700according to the present embodiment, the SAM750may effectively protect the encapsulation unit710. For example, the SAM750may be formed on a surface of an outmost inorganic film of the encapsulation unit710, cracks may be prevented from occurring in the inorganic film of the encapsulation unit710, and the surface of the outmost inorganic film of the encapsulation unit710may be effectively protected.

The encapsulation unit710and the SAM750may be bonded to each other, and delamination phenomena of a surface of the encapsulation unit710may be reduced.

The end portion of the SAM750may control the surface energy of the SAM750, and the adhesive properties between the SAM750and the adhesive layer760, which may be formed on an upper surface of the SAM750, may be improved.

The SAM750may reduce the delamination of the adhesive layer760from the surface of the encapsulation unit710and also reduce damage to the surface of the encapsulation unit710by the adhesive layer760.

By using the above-described structure, the polarization layer770may be stably disposed on an upper portion of the adhesive layer760, and sequentially, the touch panel780and the cover member790may be stably disposed over the adhesive layer760. For example, the SAM750may effectively protect the surface of the encapsulation unit710in a case of a potential increase of stress applied to the surface of the encapsulation unit710when a plurality of members, such as the polarization layer770, the touch panel780, and the cover member790, are disposed over the encapsulation unit710.

By way of summation and review, a display apparatus may include an encapsulation unit to protect components of the display apparatus. During use or manufacture of the display apparatus, cracks may occur in the encapsulation unit, or the encapsulation unit may be damaged. When the display apparatus is manufactured or used, various members may be disposed above the encapsulation unit, and the display apparatus may have limitations to protect the encapsulation unit through the various members and attach the various members to the encapsulation unit.

One or more exemplary embodiments include a display apparatus having excellent durability and user convenience.
