Abstract
An organic light-emitting display apparatus includes an organic light-emitting diode, a driving transistor configured to control an amount of electric current flowing to the organic light-emitting diode from a power line, a compensation transistor configured to diode-connect the driving transistor in response to a voltage applied to first and second compensation gate electrodes of the compensation transistor, and a gate insulating layer between the compensation gate electrodes and a compensation active region of a compensation transistor. A layer structure of the gate insulating layer between the first compensation gate electrode and the compensation active region is different from a layer structure of the gate insulating layer between the second compensation gate electrode and the compensation active region.
