Light control film, a display device, and a method for producing a light control film

Light control film has a light shielding layer and the light diffusion portion, the portion of the area of ​​S1, the light-shielding layer is in contact with one surface of the base material, the area of ​​a portion where the low refractive index portion is exposed from between the light incident end surface S2 that when you, (S1-S2) / S1 × and the light-shielding layer and the light diffusion portion so as to satisfy the 100 ≧ 50 is formed.
