THIN FILM TRANSISTOR, METHOD OF FABRICATING THE SAME, AND ORGANIC LIGHT EMITTING DIODE DISPLAY DEVICE INCLUDING THE SAME

摘要

A thin film transistor includes: a substrate; a semiconductor layer disposed on the substrate, and including a channel region, source and drain regions, and edge regions having a first impurity formed at edges of the source and drain regions, and optionally, in the channel region; a gate insulating layer insulating the semiconductor layer; a gate electrode insulated from the semiconductor layer by the gate insulating layer; and source and drain electrodes electrically connected to the semiconductor layer.
