Thin film transistor and flat panel display device including the same

Abstract

A thin film transistor including a stop layer is disclosed. In one embodiment, the thin film transistor includes a substrate, a gate electrode formed on the substrate, a source electrode and a drain electrode insulated from the gate electrode, a semiconductor layer insulated from the gate electrode and having: a channel region which is electrically connected to the source electrode and the drain electrode, and a groove for separating at least the channel region from adjacent thin film transistors, and a stop layer formed below the semiconductor layer. According to one embodiment of the invention, a semiconductor layer can be easily patterned without using a dry or wet etching technique such as photolithography.
