A viewing angle extending film (a light diffusing member) includes a base material with optical transparency, a plurality of light-shielding layers dotted on one surface of the base material, and a transparent resin layer (optically transparent material layer) provided on the one surface of the base material. At least a light-shielding layer, which is part of the plurality of light-shielding layers, has a planar shape surrounded by a first figure and a second figure contained in the first figure or a planar shape surrounded by at least part of the first figure and at least part of the second figure overlaid with the first figure. Hollow portions are provided in a formation region of the light-shielding layers, each hollow portion being shaped so that a cross-sectional area obtained by cutting along a plane parallel to the one surface of the base material is large on the light-shielding layer side and is gradually decreased as being away from the light-shielding layer. A part other than the hollow portions is taken as a light transmitting portion.
