Abstract
In an electro-optical device, a light-transmitting cover is disposed in mirrors, and when light is applied toward the mirrors through the light-transmitting cover, the temperature of the light-transmitting cover tires to increase due to the applied light. Here, in the electro-optical device, first metal portions that are in contact with the light-transmitting cover and the element substrate are formed. For this reason, it is possible to release the heat of the light-transmitting cover to a substrate through the first metal portions and the element substrate.
