SEMICONDUCTOR DEVICE

Provided is a semiconductor device capable of maintaining the flatness of a glass substrate and sufficiently protecting an end portion of the glass substrate. A semiconductor device according to one aspect of the present disclosure includes: a glass substrate including a first surface, a second surface opposite to the first surface, and a first side surface between the first surface and the second surface; wirings provided on the first and second surfaces; a first insulating film that covers the first surface; a second insulating film that covers the second surface; and a third insulating film that covers the first side surface, the third insulating film being continuous with at least one of the first and second insulating films.
