1. A planar optical member comprising:
a planar structure body comprising:
a plurality of linear bodies formed of optically transparent materials which are arrayed substantially in parallel, and
a plurality of binding members which are arranged in a direction which intersects with the plurality of the linear bodies and which bind the plurality of the linear bodies in a state of being arrayed substantially in parallel, the plurality of binding members fixing the plurality of linear bodies such that the plurality of linear bodies do not individually rotate,
wherein the linear bodies comprise
a reflective surface, which reflects light which is incident to the linear bodies along a direction which intersects with a length direction of the linear body, and
a refractive surface which refracts the light, and
in at least a part of the planar structure body,
orientations of the reflective surfaces of at least some of the linear bodies out of the plurality of the linear bodies substantially match, and
orientations of the refractive surfaces of at least some of the linear bodies out of the plurality of the linear bodies substantially match.
