An organic light-emitting display apparatus includes an emission pixel in a display area and a spare pixel circuit in a repair area outside the display area. The emission pixels includes a plurality of sub emission pixels each including a driving unit for generating a driving current corresponding to input data signals and an emission device for emitting light by using the driving current. The spare pixel circuit is coupled to a repair line that is coupled to the emission device of one of the sub emission pixels. The spare pixel circuit includes a plurality of driving transistors corresponding to the plurality of sub emission pixels.
