Abstract: An organic light-emitting display apparatus including an organic light-emitting diode emitting visible light, a driving thin film transistor driving the organic light-emitting diode, and a compensation thin film transistor. The compensation thin film transistor includes a compensation gate electrode, a compensation semiconductor layer, a compensation source electrode, and a compensation drain electrode. The compensation gate electrode includes a first gate electrode, and a second gate electrode electrically connected to the first gate electrode. The compensation drain electrode is electrically connected to the driving gate electrode of the driving thin film transistor. The compensation semiconductor layer includes a first semiconductor region overlapping the first gate electrode and a second semiconductor region overlapping the second gate electrode and disposed further from the compensation drain electrode than the first semiconductor region, and an area of the first semiconductor region is different than an area of the second semiconductor region.

Abstract: A display device and method of manufacturing the same are disclosed. In one aspect, the display device includes a first line extending in a first direction, a second line extending in a second direction, and a storage capacitor electrically connected to at least one of the first line and the second line. The first line includes a first metal pattern layer extending in the first direction, an intermediate insulating layer formed over the first metal pattern layer, and a second metal pattern layer formed over the first metal pattern layer and the intermediate insulating layer. The second metal pattern layer extends in the first direction. The first line also includes a third metal pattern layer electrically connecting the first metal pattern layer to the second metal pattern layer via a contact hole.
