Abstract

An object of the present invention is to prevent the deterioration of a TFT (thin film transistor). The deterioration of the TFT by a BT test is prevented by forming a silicon oxide nitride film between the semiconductor layer of the TFT and a substrate, wherein the silicon oxide nitride film ranges from 0.3 to 1.6 in a ratio of the concentration of N to the concentration of Si.
