DISPLAY UNIT

To reduce a size of a device and simplify control for adjusting a position irradiated with emitted light.SOLUTION: A display device 1 of an embodiment comprises: a light output unit 3 that emits light; an optical member 41 that reflects the light emitted from the light output unit 3 and outputs the light to the outside; a movable member that accommodates the optical member 41 therein; a stationary member that accommodates the movable member; a support mechanism by which the movable member is rotatably supported with respect to the stationary member, with a first axis and a second axis intersecting a direction orthogonal to a reflection surface of the optical member as rotation axes; and a driving mechanism that causes the movable member to rotate with respect to the stationary member.SELECTED DRAWING: Figure 1 【課題】装置を小型化し、出射される光が照射する位置を調整するための制御を簡略化する。【解決手段】一実施形態の表示装置１は、光を出射する光出力部３と、光出力部３から出射した光を反射して外部に出力させる光学部材４１と、光学部材４１が内部に収容される可動部材と、可動部材が収容される固定部材と、光学部材の反射面と直交する方向と交差する第１軸及び第２軸を回転軸として、可動部材が固定部材に対して回転可能に支持される支持機構と、可動部材を固定部材に対して回転させる駆動機構と、を備える。【選択図】図１
