In a TFT using a crystalline semiconductor film of a bottom gate type, a gate insulating film is flattened. On a substrate, an underlying film, a gate wiring and a gate insulating film are accumulated in this order. The gate insulating film includes a flattening film including an insulating organic resin film, such as BCB, polyimide and acrylic, and an insulating inorganic film. Because the surface of the gate insulating film is flattened by the flattening film, a flat amorphous semiconductor film can be formed on the surface thereof. Therefore, in the laser crystallization, since no difference in focal point of the laser light is formed among each position of the semiconductor film, crystallization can be uniformly conducted. Because the edge part of the gate wiring can be covered with the thick flattening film, implantation of an electron or a hole to the gate insulating film, and electrostatic breakage of the gate insulating film can be prevented.
