| 英文摘要 | An image display apparatus (1) having a case supporting laser light source apparatuses emitting laser light of green color (2), red color (3), and blue color (4), a projection optical system (8). The case includes: a front wall (23) to which the blue color laser light source apparatus (4) is mounted and a projection outlet (8a) of the projection optical system is provided; and a side wall (24) that is connected to the front wall and to which the red color laser light source apparatus (3) and the green color laser light source apparatus (2) are mounted. The image display apparatus further includes dichroic mirrors (14,15) guiding the laser light of respective colors to the projection optical system side. Either of the dichroic mirrors reflects laser light having a wavelength shorter than or equal to the wavelength of the green color laser light. A cooler (91,92) that cools the laser light source apparatuses is provided on the side wall side. |
