Abstract:
1. A thin film transistor comprising: a semiconductor layer comprising polycrystalline silicon and including a source region, a drain region and a channel region, wherein the polycrystalline silicon is crystallized by irradiating an amorphous silicon layer with a laser beam through an organic layer disposed on the amorphous silicon layer, a gate electrode in spaced relationship to the channel region; a gate insulating layer between the gate electrode and the semiconductor layer, wherein an interface between the gate insulating layer and the semiconductor layer is substantially free of protrusions; and a source electrode and a drain electrode electrically connected to the source region and the drain region, respectively, wherein the organic layer comprises a material represented by the formula X—Y—Z, wherein X is H or CH3, Y is C4 to C50 of a linear or a branched chain, and Z is a silane group which comprises at least a halogen element.
