Abstract:
Provided is a virtual image display device which, despite having a simple configuration, is capable of displaying additional information such as a danger signal superimposed on an object such that the additional information can be appropriately recognized. This virtual image display device 100 is provided with: an image forming element 11 which is a rendering device; a main body optical system 13 which is an expansion/projection optical system which expands an image of the image forming element 11; and a display screen 20. The virtual image display device is further provided with: an arrangement changing device 62 which changes the projection distance by moving the image forming element 11 in the optical axis AX direction; and a display control unit 18 which causes a plurality of display images (virtual images) IM having different projection distances to be displayed, by causing the image forming element 11 and the arrangement changing device 62 to operate in conjunction with each other.
