摘要： A thin film transistor “TFT”) substrate includes a substrate, an active layer over the substrate, and first and second TFTs over the substrate. The active layer includes: a first drain region, a first channel region and a first source region, which function as a drain, a channel and a source of the first TFT: a first lightly doped region between the first drain region and the first channel region: a second lightly doped region between the first channel region and the first source region: and a second drain region, a second channel region and a second source region, which function as a drain, a channel and a source of the second TFT. An impurity concentration at the second drain or source region is lower than an impurity concentration at the first drain or source region and higher than an impurity concentration at the first or second channel region.
