Abstract
There is provided a thin film transistor, comprising a substrate () and a gate layer (), a gate insulating layer (), an active layer (), an electrode metal layer () and a passivation layer () which are formed on the substrate () in sequence; the electrode metal layer () comprises a source electrode () and a drain electrode (), which are separated from each other with a channel region being defined therebetween; between the gate layer () and the substrate (), there is formed a first transparent conductive layer (); between the active layer () and the electrode metal layer (), there is formed a second transparent conductive layer (). The transparent conductive layers () are added so that adhesive force between the gate metal layer () and the substrate () is enhanced, diffusion of the electrode metal to the active layer () is prevented.
