The centers of the slit patterns arranged at the first to fourth slit regions in the horizontal direction are placed at the same line. The slit patterns arranged at the respective slit regions in the vertical direction are spaced from each other with a distance 8*d. Alternatively, the first to fourth slit regions may be arranged in reverse order, or in the vertical direction.

    摘要: In a method of manufacturing a thin film transistor according to the present invention, an amorphous silicon thin film is firstly formed on an insulating substrate and a planarization layer is formed thereon. Thereafter, the amorphous silicon thin film is crystallized by a solidification process using a laser-irradiation to form a polysilicon thin film. Next, the polysilicon thin film and the planarization layer are patterned to form a semiconductor layer, and a gate insulating layer covering the semiconductor layer is formed. Then, a gate electrode is formed on the gate insulating layer opposite the semiconductor layer. Next, impurities are implanted into the semiconductor layer to form a source region and a drain region opposite each other with respect to the gate electrode, and a source electrode and a drain electrode electrically connected to the source region and the drain region, respectively, are formed.
