A virtual image display device includes an intermediate image formation unit on which a real image based on an image display light is formed. The intermediate image formation unit includes a principal surface on which a first area, a second area, and a third area are arranged in a stated order in a predetermined direction, and a reflective part. The first area is provided with a transmission-type screen on which a first display light forms an image, and the third area is provided with a reflection-type screen on which a second display light forms an image. The first display light is transmitted through the transmission-type screen, reflected by the reflective part, transmitted through the second area, and output toward a projection mirror. The second display light is reflected by the reflection-type screen and output toward the projection mirror.
