An electro-optical device includes a liquid crystal device; a holder that holds the liquid crystal device; and an incident window bored through the holder, the incident window allowing a light beam emitted from a light source to be transmitted therethrough to the liquid crystal device. A window frame of the incident window has low reflectivity portions having a low reflectivity of diagonal light toward the liquid crystal device, the diagonal light being included in the light beam directed to the window frame.
