PROBLEM TO BE SOLVED: To stabilize characteristics of a device provided with a thin film transistor. A semiconductor device includes a substrate, a thin film transistor that is supported by the substrate and includes a semiconductor layer, and at least part of the semiconductor layer when viewed from a normal direction of the substrate. The insulating protective layer 30 is disposed, and the insulating protective layer 30 includes polyparaxylylene as a main component and at least one metal element selected from the group consisting of palladium, tantalum, and vanadium, gallium, gold, And at least one element selected from the group consisting of argon, cesium, sodium and magnesium.
