摘要：
A thin film semiconductor device is provided that includes a semiconductor thin film and a gate electrode. The semiconductor thin film has an active region turned into a polycrystalline region through irradiation with an energy beam. The gate electrode is provided to traverse the active region. In a channel part that is the active region overlapping with the gate electrode, a crystalline state is changed cyclically in a channel length direction, and areas each having a substantially same crystalline state traverse the channel part.
