The present disclosure relates to a light control film having nano (or nano-scale) light absorbing layer and a display using the same. A light control film according to the present disclosure includes a lower layer having a first axis and a second axis, a middle layer having a predetermined thickness disposed between the lower layer and the upper layer, and a plurality of nano light absorbing layers arrayed with a predetermined intercals 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 selected from any one of 10:1 to 20:1.

Light control film having nano light absorbing layer and display using the same

A light control film can include a lens part including a plurality of optical patterns; a viewing angle controller including a plurality of slits; and a first based film disposed between the lens part and the viewing angle controller, in which the viewing angle controller has a light transmitting part and a light absorbing part which are alternately disposed, the light absorbing part being disposed in each of the plurality of slits.

Light control film and display apparatus including the same

The present disclosure relates to a backlight unit and a display device including the backlight unit. The backlight unit includes a first pattern in a first region of a light guide plate including a light incidence surface and a second pattern in a second region of the light guide plate extending from the first region, so that, in the first region, a directional angle of light can be improved so as to prevent the occurrence of hot spots, and in the second region, a line light source can be converted into a plane light source.
