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.
其他摘要	一种图像显示装置（1），其具有支撑发射绿色（2），红色（3）和蓝色（4）的激光的激光光源装置的壳体，投影光学系统（8）。壳体包括：前壁（23），蓝色激光光源装置（4）安装在前壁上，并提供投影光学系统的投影出口（8a）;侧壁（24）连接到前壁，红色激光光源装置（3）和绿色激光光源装置（2）安装在侧壁上。图像显示装置还包括分色镜（14,15），其将各种颜色的激光引导到投影光学系统侧。任何一个二向色镜都反射波长短于或等于绿色激光波长的激光。冷却激光光源装置的冷却器（91,92）设置在侧壁侧。
主权项	An image display apparatus employing a semiconductor laser as a light source, comprising: a first laser light source apparatus emitting a first color laser light; a second laser light source apparatus emitting a second color laser light having a wavelength different from a wavelength of the first color laser light; a third laser light source apparatus emitting a third color laser light having a wavelength between the wavelength of the first color laser light and the wavelength of the second color laser light; a projection optical system externally projecting the laser light of respective colors; and a case supporting the laser light source apparatuses of respective colors and the projection optical system, wherein the case includes a front wall and a side wall that is connected to the front wall; on the front wall, either of the first or the second laser light source apparatus is mounted and a projection outlet of the projection optical system is provided; and on the side wall, the other of the first or the second laser light source apparatus and the third laser light source apparatus are mounted.
