<p>An optical device body ( 440 A) includes an electro-optic device ( 440 B), a projection lens ( 445 ), and a supporting structure ( 446 ). The supporting structure ( 446 ) includes a supporting structure body ( 4461 ) attached on a base end of the projection lens ( 445 ), an upper mount ( 4462 ) and a lower mount ( 4463 ) respectively fixed on an upper surface and a lower surface of a cross dichroic prism ( 444 ), and spacers ( 4464 ) interposed between: the supporting structure ( 4461 ); and the upper mount ( 4462 ) and the lower mount ( 4463 ). The spacers ( 4464 ) are respectively disposed near four corners of a planar rectangular light irradiation surface of the cross dichroic prism ( 444 ).</p> |
