<p><P>PROBLEM TO BE SOLVED: To provide an illuminator which has a plurality of light sources and whose upsizing can be suppressed. <P>SOLUTION: The illuminator 100 includes a first light source device 10, a second light source device 20, a third light source device 30, a light composition optical system 50 which puts together and projects pieces of lighting luminous flux from the first light source device 10 to the third light source device 30, and an integrator optical system 700. The first light source device 10 to the third light source device 30 are so arranged that a second virtual plane V<SB>2</SB>orthogonal to a second optical axis 20ax and a third virtual plane V<SB>3</SB>orthogonal to a third optical axis 30ax are respectively orthogonal to a first virtual plane V<SB>1</SB>orthogonal to a first optical axis 10ax. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
