Abstract: An organic light-emitting display apparatus includes a substrate that includes an insulating layer, a display unit disposed on the substrate, an encapsulation member that covers the display unit, and a sealing member disposed on a non-display area of the substrate outside the display unit and between the substrate and the encapsulation member. The insulating layer comprises a first portion that corresponds to the non-display area, and comprises at least one groove formed in the first portion that extends in a direction that is not parallel to an extension direction of the sealing member. The sealing member substantially fills the at least one groove.
