Abstract:
Off-leak current of a TFT, required for a drive circuit configured with a TFT of a single conductivity type, is realized with simple manufacturing steps. The impurity concentration of a source region and a drain region of a TFT is set between 2*1018 cm−3 and 2*1019 cm−3, whereby off-leak current of the TFT can be sufficiently reduced even in a single gate structure.
