description An image display device (1) includes a housing that accommodates a plurality of laser light source devices (22, 23, 24) that emit laser light of respective colors, a light modulator (25), a projection optical system and a controller (101), a movable body that is ejectable from and retractable into the housing and includes at least the projection optical system, a first switch (106) that turns ON in a use state in which the movable body is ejected from the housing, and a second switch (107) that turns ON in response to an operation of an operating portion by a user. The laser light is emitted from the plurality of laser light source devices when both of the first switch and the second switch turn ON. Accordingly, laser light is securely prevented from being emitted in a nonuse state by a switch erroneously turned ON.
