Abstract
A thin film field effect transistor that has on a substrate, at least a gate electrode, a gate insulating layer, an active layer, a source electrode and a drain electrode, wherein the active layer includes an amorphous oxide, a carrier concentration of the amorphous oxide decreases together with lowering of a temperature thereof from room temperature, and the amorphous oxide has an activation energy of from 0.04 eV to 0.10 eV is provided. A thin film field effect transistor having high mobility and a high ON-OFF ratio, and a high-gradation electroluminescence display using the same are provided.
