Semiconductor device comprising planarized light-shielding island films for thin-film transistors

Image Number 7 for United States Patent #7804096.

A semiconductor device includes: a substrate; a plurality of island-shaped light shielding films formed on the substrate; a first insulating film formed between the plurality of light shielding films; a second insulating film formed on the first insulating film and the plurality of light shielding films; and semiconductor elements each having a semiconductor film. The step difference is not generated between an interface between the first insulating film and the second insulating film and an interface between each of the plurality of light shielding films and the second insulating film. Each of the plurality of light shielding films is disposed between each of the semiconductor films and the substrate.
