Abstract
An active layer of the thin-film transistor includes a channel region, a source region and a drain region. The source region and the drain region are respectively arranged on both sides of the channel region, and the channel region includes a polycrystalline silicon structure doped with a fifth group element. A potential difference between the source-drain region and the channel region is increased by doping with the fifth group element.
