Abstract: An organic light-emitting display includes a first pixel adjacent to a second pixel and a plurality of driving voltage lines to apply driving voltages to the first pixel and the second pixel. The driving voltage lines extend in a first direction crossing the first pixel and the second pixel and a second direction crossing the first direction. Each of the first and second pixels includes a first driving transistor and a second driving transistor that are symmetrical to each other with respect to a boundary between the first pixel and the second pixel, and a first compensation transistor and a second compensation transistor that are asymmetrical to each other with respect to the boundary.
