Abstract
The optical composite sheet 1 includes a first optical layer 10 and a second optical layer 20, and a low-refractive index layer 30 that is laminated at least between the first optical layer 10 and the second optical layer 20 and has a lower refractive index than the refractive indices of the first optical layer 10 and the second optical layer 20. The low-refractive index layer 30 is characterized by containing many particles 50 having an average particle size of 5 nm to 300 nm, a binder resin 35 that binds the surface sites of the particles 50 to each other, and gaps 36 that are formed among the particles.
Claims20
An optical composite sheet, comprising:
- a first optical layer and a second optical layer, and
- a low-refractive index layer that is laminated between at least the first optical layer and the second optical layer and has a lower refractive index than the refractive indices of the first optical layer and the second optical layer,
- wherein the low-refractive index layer contains many particles having an average particle size of 5 nm to 300 nm, a binder resin that binds the surface sites of the particles to each other, and gaps that are formed among the particles.
