Abstract:
An electronic device having a display device, said display device comprising:a P-channel thin-film transistor comprising a source region and a drain region, a channel region provided between said source region and said drain region, and an N-channel thin-film transistor comprising a source region and a drain region, a channel region provided between said source region and said drain region of said N-channel thin-film transistor, and an NB region provided between said channel region of said N-channel thin-film transistor and at least one of said source region and said drain region of said N-channel thin-film transistor, wherein said source region and said drain region of said P-channel thin-film transistor are doped with P-type and N-type dopants, wherein each of said source region and said drain region of said P-channel thin-film transistor has a first region and a second region and concentration of N-type dopant in said second region is larger than that in said first region, wherein a concentration of said P-type dopant in said first region is the same as that of said second region, wherein said P-type dopant in said source region and said drain region of said P-channel thin-film transistor has a quantity sufficient to convert conductivity type from N-type of said N-type dopant to P-type of said P-type dopant, and wherein said electronic device is selected from the group consisting of a TV camera, a personal computer, a car navigation system, a TV projection system, a video camera or a portable intelligent terminal.
