Abstract: An organic light emitting display apparatus includes active patterns arranged corresponding to a plurality of pixels, and connected to each other along a first direction, a first initialization power supply line to which a first initialization voltage is applied, a second initialization power supply line to which a second initialization voltage different from the first initialization voltage is applied, an organic light emitting diode, and an first transistor which apply the second initialization voltage to a first electrode of the organic light emitting diode.
