Thin film transistor and display device using the same and method for manufacturing the same

摘要

A thin film transistor according to an example embodiment includes: a substrate body; a semiconductor layer formed on the substrate body and comprising a polycrystalline silicon film having a surface resistance from about 2000 ohm/sq to about 8000 ohm/sq; and a source electrode and a drain electrode each contacted with the semiconductor layer and comprising a metallic material having a resistance from about 350 to about 2000 ohm.
