Abstract
Disclosed is a display apparatus including a first thin film transistor (TFT) and a second thin film transistor having a bottom gate structure and including an oxide semiconductor layer. The first TFT may be used as a switching device and the second TFT may be used as a driving device, and these TFTs have different operation properties from each other. One or more embodiments of the present disclosure provides a method of arranging a plurality of TFTs having different properties in a display apparatus. This not only provides a display apparatus with TFTs integrated at a high density but also an efficient way of driving the display apparatus.
