Abstract:
There is provided a lighting film according to one aspect of the invention including: a first substrate having optical transparency; a plurality of lighting units formed of a plurality of polygonal prism-shaped structures having optical transparency provided on a first surface of the first substrate; and gaps provided between the plurality of lighting units, in which the lighting unit is a polygon which has five vertexes in a sectional shape orthogonal to a longitudinal direction and has all of internal angles smaller than 180°, the lighting unit includes a first side which is one side of the polygon corresponding to a surface contacted with the first substrate, and a plurality of vertexes including a first vertex and a second vertex which are vertexes corresponding to both ends of the first side and a third vertex which is not positioned on the first side, a length of a perpendicular line of the first side passing the third vertex is longer than a length of a perpendicular line of the first side passing a vertex other than the third vertex among the plurality of vertexes, and a shape of the lighting unit is asymmetrical with a perpendicular line of the first side passing the third vertex as the center.
