An organic light-emitting display apparatus includes a substrate, thin film transistors (TFTs), and organic light-emitting diode elements (OLEDs). First wirings have a first width and a first height and second wirings have a second width and a second height, in which the first wirings and the second wirings are formed in at least a portion of areas between the OLEDs. Third wirings connect the first wirings and the second wirings and have a third width smaller than the first width of the first wirings and the second width of the second wirings or have a third height smaller than the first height of the first wirings and the second height of the second wirings. An insulating layer covers at least a portion of the first and second wiring portions and exposes at least a portion of the third wirings.

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.

A thin film transistor includes a semiconductor pattern on a base substrate, the semiconductor pattern including an input area, an output area, and a channel area between the input area and the output area, a first insulating layer covering the semiconductor pattern, a control electrode on the first insulating layer, the control electrode overlapping the channel area, a second insulating layer covering the control electrode, an input electrode connected to the input area, an output electrode connected to the output area, and a heat discharge electrode on the second insulating layer, the heat discharge electrode being connected to the control electrode.
