1. A light control film comprising:
a lower layer having a first axis and a second axis;
a middle layer having a thickness disposed between the lower layer and an upper layer; and
a plurality of nano light absorbing layers arrayed with predetermined intervals along the first axis in the middle layer, each of the nano light absorbing layer having a width along the first axis, a length along the second axis and a height corresponding to the thickness of the middle layer,
wherein a ratio between the interval and the width of the nano light absorbing layer is in a range of 10:1 to 20:1,
wherein the plurality of nano light absorbing layers includes a first nano light absorbing layer and a second nano light absorbing layer neighboring with the interval between each other, and
wherein the middle layer includes a lower prism part and an upper prism part, the lower prism part positioned at a lower area based on an inclined surface connecting from an upper end of the first nano light absorbing layer to a lower end of the second nano light absorbing layer, and the upper prism part positioned at an upper area based on the inclined surface.
