ABSTRACT:
A light control film including transparent layers and light absorbing layers arranged alternately is provided. The film is capable of controlling emission angle of light from the light source relatively strictly, and the light use efficiency thereof is improved. Further, a lighting device and a display device using thereof are provided. A transparent layer includes a high refractive index area and a low refractive index area, and further, a light reflective layer is provided at least on the light incident surface of the light absorbing layer out of the light absorbing layer and the low refractive index area. Thereby, a light control film having high light use efficiency is realized by utilizing reflection on the refractive index interface. At the same time, a lighting device capable of switching lighting angles and a display device capable of switching view angles, incorporating the control film, are realized.
