Abstract: In an electro-optical device, a mirror and the like which is formed on an element substrate is sealed using a sealing member. The sealing member is provided with a frame section and a cover section. In addition, the sealing member is provided on one face of the element substrate so that the mirror is surrounded by the element substrate and the sealing member and such that the mirror is positioned between a portion of the cover section and the element substrate. The sealing member is formed of a light-transmitting member having a frame section and a cover section which are integrally formed, and there is no interface between the frame section and the cover section.
