After adopting the above technical scheme, the utility model compared with the background art, has the following advantages that：
1, scattering particles is not added in light diffusing sheet base material in the utility model, will not be made to the absorption of light because of scattering particles
Light source can be made to spread evenly at the microstructure unit of optical energy loss, and diffusion layer, in this way, both ensure that light source diffusion
Uniformity reduces light loss of energy again, improves display effect.
2, the static conductive structure of the utility model reduces the friction between light diffusing sheet and other optical diaphragms, static conductive coating
The electrostatic that light diffusing sheet is generated by friction is eliminated, anti-static effect is good, avoids the light in the damage by static electricity display device of accumulation
Electric device.
