An electro-optical device comprises: an upper frame formed of a metal having an opening formed therein and having open portions formed in at least two corners thereof; an electro-optical panel having an electro-optical substance sealed between a pair of plates and arranged below the upper frame; a light guide plate arranged below the electro-optical panel; and an intermediate frame having a frame shape, arranged below the light guide plate, and being applied to support the electro-optical panel and the light guide plate. The electro-optical panel and the light guide plate is sandwiched between the upper frame and the intermediate frame. The peripheral edge along the four sides of the electro-optical panel is bonded to the upper frame by an adhesion element, and at least two corners of the intermediate frame are exposed in the open portions of the upper frame.
