To provide a light source unit and a video display device that are compact and capable of displaying a high-quality video.SOLUTION: The light source unit comprises: a display device having a pixel row including a plurality of pixels arrayed along a first direction; and an image-forming optical system including a movable optical system which the light emitted from the display device enters and which is movable around an axis parallel along the first direction and emits light at an angle corresponding to the movable state, and an output element which light enters via the movable optical system, with the light emitted from the output element forming an image. The image-forming optical system has substantially telecentricity on the image side, and the light emitted from the display device has substantially Lambertian light distribution.SELECTED DRAWING: Figure 1

    【課題】小型であり、高品位な映像を表示できる光源ユニットおよび映像表示装置を提供する。【解決手段】光源ユニットは、第1方向に沿って配列された複数の画素を含む画素列を有する表示装置と、前記表示装置から出射した光が入射され、前記第1方向に沿って平行な軸を中心に可動であり、可動状態に応じた角度で光を出射する可動光学系と、前記可動光学系を介して光が入射する出力素子と、を含み、前記出力素子から出射した光が像を形成する結像光学系と、を備える。前記結像光学系は、前記像側において略テレセントリック性を有し、前記表示装置から出射する光が略ランバーシアン配光を有する。【選択図】図1
