Abstract
A semiconductor device includes a thin film transistor and a thin film diode on a same substrate. A semiconductor layer () of the thin film transistor and a semiconductor layer () of the thin film diode are crystalline semiconductor layers formed by crystallizing the same non-crystalline semiconductor film. The thickness of the semiconductor layer () of the thin film diode is greater than the thickness of the semiconductor layer () of the thin film transistor, and the surface of the semiconductor layer () of the thin film diode is rougher than the surface of the semiconductor layer () of the thin film transistor.
