PROBLEM TO BE SOLVED: To provide an intermediate image forming device that can reduce the size of an apparatus to which the intermediate image forming device is attached and has high visibility.SOLUTION: An intermediate image forming device 360 is an intermediate image forming device that transmits projected image display light and forms a real image based on the image display light, and comprises a concave lens 364 that changes the direction of a principal ray of the transmitted image display light, and light distribution means 362 that distributes light so that the principal ray has a predetermined light distribution angle. The light distribution means 36 is a transmission type screen that disperses transmitted light.SELECTED DRAWING: Figure 7
