Quantum-dot film and the method to make the same

A quantum-dot film, comprising:

• a quantum-dot layer, comprising a binder, a plurality of quantum dots, and a plurality of diffusing particles, wherein the plurality of quantum dots and the plurality of diffusing particles are dispersed in the binder with a concentration of the quantum dots in the quantum-dot layer being 0.05-20 wt % and a concentration of the diffusing particles in the quantum-dot layer being 2-40 wt %, wherein the plurality of quantum dots are capable of being water-resistant and oxygen-resistant, and there is no barrier layer disposed over the quantum-dot layer for protecting the plurality of quantum dots from water or oxygen, wherein a coating layer is coated on each of a first major surface and a second major surface of the quantum-dot layer, respectively, each said coating layer comprising a structured surface, wherein the first major surface and the second major surface are two opposite surfaces of the quantum-dot layer.
