Abstract

An embodiment of the present invention is a microcrystalline semiconductor film having a thickness of more than or equal to 70 nm and less than or equal to 100 nm and including a crystal grain partly projecting from a surface of the microcrystalline semiconductor film. The crystal grain has an orientation plane and includes a crystallite having a size of 13 nm or more. Further, the film density of the microcrystalline semiconductor film is higher than or equal to 2.25 g/cm3 and lower than or equal to 2.35 g/cm3, preferably higher than or equal to 2.30 g/cm3 and lower than or equal to 2.33 g/cm3.
