Abstract
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.
Claims4
An electro-optical device comprising:
- a liquid crystal device;
- and
- a holder that holds the liquid crystal device, the holder including a window frame having an incident window through which a light beam emitted from a light source is transmitted to the liquid crystal device, the window frame having a low reflectivity portion with a low reflectivity with respect to diagonally incident light of the light beam from the light source, the low reflectivity portion comprising a low-reflectivity layer around a periphery of the window frame.
