<P>PROBLEM TO BE SOLVED: To provide an illuminator, an image display apparatus and a polarization conversion/diffusion member capable of more reliably reducing speckle noise. <P>SOLUTION: An illuminator comprises: a laser light source for emitting laser light; and a polarization converter 43 having a plurality of areas for converting the laser light emitted from the laser light source into the laser light having a plurality of kinds of polarization directions to exit. The illuminator diffuses the laser light emitted from the laser light source or the laser light exiting from the polarization converter 43 and illuminates a projected surface 50. <P>COPYRIGHT: (C)2013,JPO&INPIT |
