PROBLEM TO BE SOLVED: To provide a virtual image display device that is small in an amount of heat to be transmitted from a display element to a screen.SOLUTION: A virtual image display device comprises: an image projection device 3 that projects an image; and an observation optical system 2 that forms a virtual image of the image. The image projection device has: a display element 31 upon which an emitting light ray from a light source is incident; a first image formation optical system 32 upon which the emitting light ray from the display element is incident; a second image formation optical system 34 upon which the emitting light ray from the first image formation optical system is incident; and a screen 4 on which a light flux emitted from the second image formation optical system is projected and which emits the light flux to the observation optical system. The first image formation optical system is configured to form a first intermediate image 50 between the display element and the screen, and the second image formation optical system is configured to form a second intermediate image 51 on the screen.SELECTED DRAWING: Figure 1

    【課題】 表示素子からスクリーンに伝達する熱量が小さい虚像表示装置を提供する。【解決手段】 画像を投影する画像投影装置3と、画像の虚像を形成する観察光学系2と、を備え、画像投影装置は、光源からの出射光線が入射する表示素子31と、表示素子からの出射光線が入射する第1結像光学系32と、第1結像光学系からの出射光線が入射する第2結像光学系34と、第2結像光学系から出射した光束が投影され、観察光学系に光束を出射するスクリーン4と、を有し、第1結像光学系は、表示素子とスクリーンの間に第1中間像50を形成し、第2結像光学系は、スクリーン上に第2中間像51を形成することを特徴とする、虚像表示装置。【選択図】図1
