SEMICONDUCTOR DEVICE, METHOD FOR MANUFACTURING SAME, AND DISPLAY DEVICE

摘要

A semiconductor device which comprises a thin-film transistor and a thin-film diode on a same substrate.  A semiconductor layer (109) of the thin-film transistor and a semiconductor layer (110) of the thin-film diode are crystalline semiconductor layers formed by crystallizing a same crystalline semiconductor film.  The semiconductor layer (110) of the thin-film diode has a larger thickness than the semiconductor layer (109) of the thin-film transistor.  The surface roughness of the semiconductor layer (110) of the thin-film diode is larger than the surface roughness of the semiconductor layer (109) of the thin-film transistor.
