<P>PROBLEM TO BE SOLVED: To provide an electrooptical device capable of preventing specular reflection of returned light in a peripheral circuit region and emission of the returned light from an element substrate side, when the returned light is made incident on the element substrate, to provide a manufacturing method of the electrooptical device, and to provide a projection-type display device. <P>SOLUTION: In the electrooptical device 100, a plurality of light-scattering concavo-convex parts 10t (spherical concave parts 10v) are formed in the peripheral circuit region 10d of a light-transmissive substrate 10s used for the element substrate 10. Thereby, even when the returned light of modulated light is made incident, directed toward the peripheral circuit region 10d of the element substrate 10, the returned light is reflected at the spherical concave parts 10v to be scattered. Thus imaging of the peripheral circuit region 10d in an outer edge part of a projected image, caused by reflection of the returned light at the peripheral circuit region 10d, can be prevented. <P>COPYRIGHT: (C)2009,JPO&INPIT |
