Abstract
The present invention provides a high quality electronic optical device by preventing flaws and dust from adhering on substrates, between which a liquid crystal is inserted, and by suppressing a temperature increase caused by irradiation of light from a light source. The present invention also provides a projection type device using the electronic optical device and a method for producing the electronic optical device. Flaws and dust are never adhered on an outer face of an active matrix substrate because a planar surface of a third substrate is adhered with an adhesive on the outer face of the active matrix substrate in the electronic optical device. Even when flaws and dust are adhered on an outer face of the third substrate, such flaws and dust are not displayed on the projection image. Forming a light-shielding film on the third substrate allows the design margin of a case to be enlarged.
