PROBLEM TO BE SOLVED: To provide a mirror unit and a display device with which it is possible to suppress the distortion of a mirror surface.SOLUTION: A mirror unit 30 comprises a concave mirror 31 including a mirror surface 31a that reflects light, and a holder 35 for holding the concave mirror 31 while being adhered to the concave mirror 31. The concave mirror 31 is provided with first to third positioning projections. The holder 35 is also provided with: a first holder-side positioning part 36a that determines, through contact with the first positioning projection, the position of the concave mirror 31 relative to the holder 35 in at least a direction X among XY plane coordinates parallel to the mirror surface 31a; a second holder-side positioning part 36b that determines, through contact with a second positioning projection 32b, the position of the concave mirror 31 relative to the holder 35 in at least a direction Y among the XY plane coordinates; and a third holder-side positioning part 36c that determines, through contact with a third positioning projection 32c, the position of the concave mirror 31 relative to the holder 35 in at least a direction Z orthogonal to the XY plane.SELECTED DRAWING: Figure 3

    【課題】鏡面の歪みを抑制することができるミラーユニットおよび表示装置を提供する。【解決手段】ミラーユニット30は、光を反射する鏡面31aを含む凹面鏡31と、凹面鏡31に接着された状態で、凹面鏡31を保持するホルダ35と、を備える。凹面鏡31は、第1〜第3の位置決め凸部を備える。また、ホルダ35は、第1の位置決め凸部との接触を通じて、鏡面31aに沿うXY面座標のうち少なくともX方向における凹面鏡31のホルダ35に対する位置を決める第1のホルダ側位置決め部36aと、第2の位置決め凸部32bとの接触を通じて、XY面座標のうち少なくともY方向における凹面鏡31のホルダ35に対する位置を決める第2のホルダ側位置決め部36bと、第3の位置決め凸部32cとの接触を通じて、少なくとも、上記XY面に直交するZ方向における凹面鏡31のホルダ35に対する位置を決める第3のホルダ側位置決め部36cと、を備える。【選択図】図3
