A method of forming a liquid crystal display device includes forming an amorphous silicon layer over a substrate and forming a light reflecting layer only over a first portion of the amorphous silicon layer. The amorphous silicon layer is then irradiated with a laser to convert it to a polysilicon layer. The light reflecting layer partially reflects the light away from the first portion of the amorphous silicon layer such that a first portion of the polysilicon layer has a first polysilicon grain size and a second portion of the polysilicon layer has a second polysilicon grain size, which is larger than the first polysilicon grain size. A first plurality of thin film transistors having reduced leakage current characteristics may then be formed from the first portion of the polysilicon layer.
