Organic light-emitting display

An organic light-emitting display, comprising:

• 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 extending in a first direction crossing the first pixel and the second pixel and in a second direction crossing the first direction, wherein the first pixel includes a first driving transistor and a first compensation transistor and the second pixel includes a second driving transistor and a second compensation transistor and wherein:
• the first driving transistor and the second driving transistor are symmetrical to each other with respect to a boundary between the first pixel and the second pixel;
• and
• the first compensation transistor and the second compensation transistor are asymmetrical to each other with respect to the boundary.
