Abstract: A display device may include a thin film transistor disposed on a substrate, and a display element electrically connected to the thin film transistor. The thin film transistor may include an active pattern including polycrystalline silicon, a gate insulation layer disposed on the active pattern, and a gate electrode disposed on the gate insulation layer. An average value of grain sizes of the active pattern may be in a range of about 400 nm to about 800 nm. An RMS value of a surface roughness of the active pattern may be about 4 nm or less. A method of manufacturing a polycrystalline silicon layer may include cleaning an amorphous silicon layer with hydrofluoric acid, rinsing the amorphous silicon layer with hydrogenated deionized water, and irradiating the amorphous silicon layer with a laser beam having an energy density of about 440 mJ/cm2 to about 490 mJ/cm2.

Abstract: A laser irradiation method includes a first scanning wherein a laser beam is scanned in a first region having a width in the X direction and a length in the Y direction by moving a laser irradiation area on the surface of the substrate along the Y direction using a spot laser beam, and a second scanning wherein laser beam is scanned in a second region having a width in the X direction and a length in the Y direction by moving a laser irradiation area on the surface of the substrate along the Y direction using the spot laser beam. A center of the second region is spaced apart from a center of the first region in the X direction.
