THIN FILM TRANSISTOR AND ORGANIC LIGHT EMITTING DISPLAY DEVICE HAVING THE SAME

摘要

A thin film transistor (TFT) and an organic light emitting display device having the same are disclosed. In one embodiment, a TFT includes a gate electrode formed on a substrate. A gate insulating layer is formed on the substrate having the gate electrode. An active layer is formed on the gate insulating layer. A source electrode is formed over the active layer. A drain electrode is formed to substantially surround at least three surfaces of the source electrode on the active layer.
