Abstract
A thin film transistor (TFT) comprises: an active layer formed on a substrate; a gate insulating layer formed on the active layer; a gate electrode including a first gate region and a second gate region formed on portions of the gate insulating layer and spaced apart with a separation region interposed therebetween; an interlayer insulating layer formed on the gate insulating layer and the gate electrode, and having an opening formed to expose portions of the gate insulating layer and the gate electrode around the separation region; a gate connection electrode formed on the interlayer insulating layer and connected to the first gate region and the second gate region through the opening; and source and drain electrodes formed on the interlayer insulating layer. The TFT and the OLED display device have excellent driving margin without a spatial loss.
