To provide a display device capable of improving the degree of freedom of an arrangement position of a video source.SOLUTION: An optical sheet 20 reflecting incident video light comprises: an optical shape layer 21 in which a plurality of unit optical shapes 21a each having an incident plane 21b, on which video light is incident, are arranged along a sheet surface; and a reflective layer 22 formed on the incident plane 21b of the optical shape layer 21, for reflecting incident light. An arrangement direction of the unit optical shapes 21a, when viewed from a thickness direction of the optical sheet 20, passes through a geometric center of the optical sheet 20 and inclines to a line parallel to a vertical direction. The unit optical shape 21a has an opposite plane 21c opposite to the incident plane 21b, and the opposite plane 21c has a fine rugged shape.SELECTED DRAWING: Figure 2

    【課題】映像源の配置位置の自由度を向上させることができる表示装置を提供する。【解決手段】光学シート20は、入射した映像光を反射する光学シート20であって、映像光が入射する入射面21bを有した単位光学形状21aがシート面に沿って複数配列された光学形状層21と、光学形状層21の入射面21bに形成され、入射した光を反射する反射層22とを備え、単位光学形状21aの配列方向は、光学シート20の厚み方向から見た場合において、光学シート20の幾何学的中心を通り、上下方向に平行な線に対して傾斜しており、単位光学形状21aは、入射面21bに対向する対向面21cを有し、対向面21cには微細な凹凸形状が形成されていることを特徴とする。【選択図】図2
