Abstract:
1. A thin film transistor, comprising: a substrate; a semiconductor layer disposed on the substrate, the semiconductor layer including a channel region and source and drain regions, and the semiconductor layer being crystallized using a crystallization-inducing metal; a gate electrode disposed to correspond to a predetermined region of the semiconductor layer; a gate insulating layer disposed between the gate electrode and the semiconductor layer to insulate the semiconductor layer from the gate electrode; source and drain electrodes respectively electrically connected to the source and drain regions of the semiconductor layer a metal other than the crystallization-inducing metal or a silicide of a metal other than the crystallization-inducing metal disposed at a predetermined depth from a surface of the semiconductor layer in a region spaced apart from the channel region in the semiconductor layer, and a length and a width of the channel region of the semiconductor layer and a leakage current of the semiconductor layer satisfy the following equation:
