Abstract
An organic light emitting display apparatus includes a first pixel and a second pixel. The first pixel includes a first data line, a first driving thin film transistor (TFT), and a first contact metal connected to the first driving TFT and in a layer at a same level as a layer of the first data line. The second pixel includes a second data line, a second driving TFT, and a second contact metal connected to the second driving TFT and in a layer at a same level as a layer of the second data line. The first gap between the first driving TFT and the first contact metal is different from a second gap between the second driving TFT and the second contact metal.
