An organic light-emitting display apparatus includes: a substrate; a thin film transistor formed on the substrate; a pixel electrode connected to at least one of the source or drain electrodes; a pixel-defining layer having a first opening exposing at least a portion of the pixel electrode and a second opening adjacent to the first opening; an intermediate layer formed on the pixel electrode, including an organic emission layer, and having a first hole corresponding to the second opening; an opposite electrode formed on the intermediate layer; and first and second auxiliary electrodes formed below the pixel-defining layer, at least portions of the first and second auxiliary electrodes are exposed through the second opening, where ends of the first and second auxiliary electrodes are spaced apart from each other, and where the opposite electrode contacts the ends of the and second first auxiliary electrodes which are exposed through the first hole.
