Abstract
A display apparatus includes a pixel and four thin film transistors (TFTs). The pixel includes a light emitting element that includes first and second electrodes and a light emitting layer. A first TFT, including a first semiconductor layer, is configured to provide a driving current to the light emitting element according to a data voltage. A second TFT, including a second semiconductor layer, is configured to control driving of the first TFT according to a gate voltage. A third TFT, including a third semiconductor layer, is configured to sense a threshold voltage of the first TFT to control driving of the first TFT. A fourth TFT, including a fourth semiconductor layer, is in the gate driving portion, configured to apply gate voltages to the second and third TFTs, wherein the fourth semiconductor layer is in a different layer from the first, second and third semiconductor layers.
