Claim:
1. An organic light-emitting display apparatus comprising: a power voltage generation unit configured to generate a first power voltage and a dummy power voltage having a different level from that of the first power voltage; a power voltage wiring network to which the first power voltage is applied; a dummy power voltage line to which the dummy power voltage is applied; a plurality of pixels each comprising an emission device and a pixel circuit electrically coupled to the power voltage wiring network; a plurality of dummy pixels each comprising a dummy circuit being configured to be connectable to the dummy power voltage line; and a plurality of repair lines each being configured to be electrically connectable to the dummy circuit of a corresponding dummy pixel among the plurality of dummy pixels and to the emission devices of corresponding pixels among the plurality of pixels wherein, when the plurality of pixels comprise a first pixel comprising a defective pixel circuit, the emission device of the first pixel is electrically disconnected from the defective pixel circuit of the first pixel, and is electrically coupled to a corresponding first dummy pixel among the plurality of dummy pixels via a corresponding first repair line among the plurality of repair lines.
