<P>PROBLEM TO BE SOLVED: To provide an image display device which can be downsized while improving the heat radiation of a green laser light source and stabilizing the output of the green laser light source. <P>SOLUTION: An image display device comprises: a red laser light source; a blue laser light source; a green laser light source composed of a semiconductor laser, which emits a non-visible light, and wavelength conversion means, which converts the non-visible light emitted from the semiconductor laser into a visible light, and emitting the visible light converted by the wavelength conversion means outside; a holder for holding the red laser light source, the blue laser light source and the green laser light source; a projector lens held by the holder; and a projection part integrally formed with the holder and provided so as to elongate a face on which the projector lens is held. In the holder, the blue laser light source is disposed on the face on which the projector lens is held, and red laser light source and the green laser light source are disposed on a different face from the face on which the projector lens is held, a face in the longitudinal direction of the green laser light source being in contact with the projection part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
