Abstract
A scanning image display device is provided that can display high-quality images even with variation in environmental conditions at a place where the device is installed. The scanning image display device includes: a laser light source that emits laser light based on image information; a scanning mirror that scans the laser light emitted from the laser light source to project an image on a projection plane; a housing that holds the laser light source and the scanning mirror; and a container formed of a base and an outer cover that accommodates the housing and is internally sealed, wherein the outer cover has a thin-wall portion that is elastically deformed with variation in pressure within the container.
