A thin film transistor includes a gate electrode on a substrate. The gate electrode includes a flat portion and an inclined portion at a side of the flat portion. A ratio of a height to a width (height/width) of the inclined portion is 1.192 or less. The thin film transistor also includes a gate insulating layer disposed on the substrate to cover the gate electrode and a polysilicon active layer on the gate insulating layer and over the gate electrode. The thin film transistor further includes a source electrode and a drain electrode respectively connected to two opposite end portions of the polysilicon active layer.
