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.

Abstract: An organic light emitting display apparatus includes first and second pixels on a display region, first and second scan lines connected to the first and second pixels respectively, and a gate driver to output a first scan signal and a second scan signal to the first and second scan lines respectively. The first pixel includes a first pixel circuit and a first organic light emitting diode (OLED). The second pixel includes a second pixel circuit and a second OLED. Each of the first and second pixel circuits includes a driving transistor to output driving current to the anode of a respective one of the first and second OLEDs. The anode of the second OLED at least partially overlaps the gate of a driving transistor of the first pixel circuit.
