    Abstract: A relay lens system forms an image displayed on an image display unit as an intermediate image. A luminous flux of the image emitted from the relay lens system reflected by a half mirror is incident to a curved combiner, and the combiner reflects the incident luminous flux to the half mirror to enable an observer to observe a virtual image through the half mirror. The relay lens system forms the intermediate image at an intermediate image forming position on an optical axis before a light reflected by the half mirror is incident to the curved combiner. The distance from the optical axis of the curved combiner to a light emission surface of the relay lens system is shorter than or equal to the distance from the optical axis of the curved combiner to a maximum reflection position.
