Abstract
In an electro-optical device, a mirror that is formed on an element substrate is sealed by a frame shaped spacer and a plate-like light-transmitting cover which is adhered to the spacer. An inorganic barrier layer is formed on an outer face of the spacer and a side face of the light-transmitting cover, and the boundary of the spacer and the light-transmitting cover is covered by the inorganic barrier layer.
