A TFT structure which is strong agains hot carrier injection is realized by disposing a Lov region 207 in an n-channel TFT 203 which forms a driver circuit. Further, Loff regions 217 to 220 and offset region are disposed in an n-channel TFT 304 which forms a pixel section, and a TFT structure of low OFF current value is realized. Further, by reducing the n-type impurity element contained in Loff regions 217 to 220 to approximately 1�1016 to 5�1018 atoms/cm3, further reduction of OFF current can be performed.
