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 capable of displaying an image; and an image-forming optical system including an input element which the light emitted from the display device enters and an output element which light having gone through the input element enters, the light emitted from the output element forming a first image corresponding to the image. The image-forming optical system has substantially telecentricity on the first image side. The light emitted from the display device has substantially Lambertian light distribution. The display device has a plurality of pixels, and the plurality of pixels are arranged so as to cancel out the secondary distortion of an optical system including the image-forming optical system.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、画像を表示可能な表示装置と、前記表示装置から出射した光が入射する入力素子と、前記入力素子を経由した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前記画像に応じた第１の像を形成する結像光学系と、を備える。前記結像光学系は、前記第１の像側において略テレセントリック性を有する。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。前記表示装置は、複数の画素を有し、複数の画素は、結像光学系を含む光学系の２次元歪を相殺するように配置されている。【選択図】図１
