Zusammenfassung:	To provide a variable focus type OST-display capable of effectively shielding regardless of a depth position of a virtual image.SOLUTION: An optical see-through type display 100 includes an image projection unit 110 and an optical shielding unit 120. The image projection unit 110 includes a micro-display 112 for displaying a virtual image, and a depth position of the virtual image can be controlled. The optical shielding unit 120 includes: a relay lens optical system 122; a SLM 124 disposed in the relay lens optical system 122; and an actuator 126 that shifts a spatial light modulator 124 in an optical axis direction of the relay lens optical system 122 in conjunction with the depth position of the virtual image.SELECTED DRAWING: Figure 2 【課題】仮想映像の奥行き位置にかかわらず、効果的な遮蔽が可能な可変焦点型ＯＳＴ－ディスプレイを提供する。【解決手段】光学式シースルー型ディスプレイ１００は、映像投影部１１０と光学遮蔽部１２０を備える。映像投影部１１０は、仮想映像を表示するマイクロディスプレイ１１２を含み、仮想映像の奥行き位置が制御可能である。光学遮蔽部１２０は、リレーレンズ光学系１２２と、リレーレンズ光学系１２２内に配置されたＳＬＭ１２４と、仮想映像の奥行き位置と連動して、空間光変調器１２４をリレーレンズ光学系１２２の光軸方向にシフトさせるアクチュエータ１２６と、を含む。【選択図】図２
