Claim 8:
9. A diffusion sheet structure, comprising:
a transparent substrate, comprising a first upper surface and a first lower surface; and
a diffusion film disposed on the transparent substrate and comprising a diffusion layer, an organic matter layer, and a plurality of nano diffusion particles, and having a second upper surface and a second lower surface, and the second lower surface is connected to the first upper surface;
wherein each of the nano diffusion particles further comprises a first portion and a second portion; the first portion forms the diffusion layer; and the diffusion layer comprises the second upper surface, and the second portion forms the organic matter layer, and the organic matter layer comprises the second lower surface; intermolecular force is generated between the second lower surface and the first upper surface;
wherein light from a backlight module enters into the transparent substrate through the first lower surface and departs the transparent substrate through the first upper surface, and the light enters into the diffusion film through the second lower surface and departs the diffusion film through the second upper surface, and the light irradiates on to the plurality of nano diffusion particles, and is then diffused, and the plurality of nano diffusion particles transmit thermal energy from the backlight module on the diffusion film;
the first portion comprises metal or carbon, and the second portion comprises an organic matter
wherein each of the nano diffusion particles further comprises a carrier;
the carrier comprises silicon or carbon;
wherein the diffusion film further comprises the organic matter layer and a carrier layer; and
the carrier forms the carrier layer.
