An organic light-emitting display apparatus includes pixels at an active area, dummy pixels at a dummy area, and repair lines coupled to the plurality of dummy pixels and connectable with the plurality of pixels. Each of the plurality of dummy pixels includes: an output node coupled to a repair line corresponding to the dummy pixel from among the plurality of repair lines, a dummy circuit including a dummy driving transistor that is coupled between a driving voltage line to which a first driving voltage is applied and the output node, and a dummy initialization circuit including a dummy anode initialization transistor coupled between a dummy initialization voltage line to which a dummy initialization voltage is applied and the output node via a connectable structure. The connectable structure includes a first conductor and a second conductor that overlap, at least partially, with each other and are electrically insulated from each other.
