| 摘要 |
A thin film transistor is provided including a transparent insulating substrate, a lower light shielding film disposed above the transparent insulating substrate, a base interlayer film disposed above the lower light shielding film, a semiconductor film disposed above the base interlayer film, wherein the semiconductor film is formed of polycrystalline silicon. A thin film transistor further comprises roughness formed at an interface between the base interlayer and the semiconductor film, a gate insulating film above the semiconductor film, and a gate electrode above the gate insulating film.
