Abstract: An organic light-emitting display device includes a driving transistor configured to control current to an organic light-emitting diode from a power voltage line, a compensation transistor configured to diode-connect the driving transistor in response to a voltage applied to a compensation gate electrode of the driving transistor, and a gate insulating layer interposed between a driving active region of the driving transistor and the driving gate electrode, and between a compensation active region of the compensation transistor and the compensation gate electrode. A dielectric constant in a first portion of the gate insulating layer between the driving active region and the driving gate electrode is greater than a dielectric constant in a second portion of the gate insulating layer between the compensation active region and the compensation gate electrode.
