Abstract
An organic light-emitting display apparatus includes: 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 connectable to the dummy power voltage line; and a plurality of repair lines each 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.
