To provide a display device capable of outputting images individually to a plurality of viewpoints and more efficiently using light from a light source.SOLUTION: A display device includes: pixels Spix arranged in a first direction Dx; a backlight BL configured to emit light to the pixels Spix; a light-blocking unit SM disposed between the pixels Spix and the backlight BL and provided with slits SL extending in a direction intersecting the first direction Dx; a reflection member 21 that covers an opposite side of the light-blocking unit SM with the backlight BL in between and reflects light toward the light-blocking unit SM; a reflection layer 11 disposed on the side of the backlight BL of the light-blocking unit SM to reflect the light toward the backlight BL side; and a reflective polarization layer 31 that is disposed closer to the backlight BL than the pixels Spix, transmits light polarized in a second direction, and reflects light polarized in a direction intersecting the second direction.SELECTED DRAWING: Figure 2 【課題】複数視点に対して個別に画像を出力可能であって、より効率的に光源からの光を利用可能な表示装置を提供する。【解決手段】表示装置は、第１方向Ｄｘに並ぶ画素Ｓｐｉｘと、画素Ｓｐｉｘに光を照射するバックライトＢＬと、画素ＳｐｉｘとバックライトＢＬとの間に配置されて第１方向Ｄｘに交差する方向に沿うスリットＳＬが形成された遮光部ＳＭと、バックライトＢＬを挟んで遮光部ＳＭの反対側を覆い遮光部ＳＭ側に光を反射する反射部材２１と、遮光部ＳＭのバックライトＢＬ側に設けられてバックライトＢＬ側に光を反射する反射層１１と、画素ＳｐｉｘよりもバックライトＢＬ側に配置されて第２方向に偏向する光を透過させ、当該第２方向と交差する方向に偏向する光を反射する反射偏光層３１と、を備える。【選択図】図２
