To realize the miniaturization of an image display apparatus having a laser light source device with a semiconductor laser as a light source.
An image display apparatus 1 includes: laser light source devices 2 to 4 which output a green color, a red color, and a blue color; dichroic mirrors 14 and 15 which guide the laser light of each color to the same optical path; a transmission type spatial light modulator 5 which modulates the laser light of each color guided by the dichroic mirrors based on a picture signal; and a projection optical system 8 for projecting a modulation laser light modulated by the spatial light modulator to the outside. The projection light system has a projection port 8a disposed in the travelling direction of the modulation laser light from the transmission type spatial light modulator.
