Embodiment
Reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, to diffusion barrier and its embodiment of manufacture method, structure, method, step, feature and the effect thereof that foundation the present invention proposes, describe in detail as after.
Below will consult correlative type, the plural embodiment according to diffusion barrier of the present invention and manufacture method thereof will be described.
At first see also Fig. 4 to shown in Figure 7, the diffusion barrier of preferred embodiment of the present invention is described.
Seeing also shown in Figure 4ly, is the exaggerative synoptic diagram of a section of the diffusion barrier in the embodiment of the invention, and this diffusion barrier 20 comprises a transparency carrier 21 and a diffusion layer 22.
Above-mentioned transparency carrier 21, in general, its thickness is approximately between 25～300 μ m, but is not limited thereto thickness, and has high light transmittance and high mechanical properties.The material of transparency carrier 21 can be polycarbonate (polycarbonate, PC), polystyrene (polystyrene), polyester (polyester), polyene (polyolefin), polyethers (polyether), polyether ester (polyether-ester), polymethacrylate (polymethacrylate) or perfluoroethylene-propylene (Polyperfluorinatedethylene propylene, PEP) or the like.
Above-mentioned diffusion layer 22 is sides that are arranged at transparency carrier 21, and diffusion layer 22 comprises a bonding agent 221, plural spherical scattering particles 222 and the non-spherical scattering particles 223 of plural number.
This bonding agent 221, being to can be a high-molecular organic material, for example is amido ethyl formate (urethane) resin, vinyl acetate (vinyl acetate) resin, epoxy (epoxy) resin, amido (amine resin) resin, acryl (acryl resin) resin or polyester (polyesterresin) resin or the like.
It should be noted that, bonding agent 221 is to have refractive index inequality with spherical scattering particles 222 and non-spherical scattering particles 222, therefore after light enters diffusion layer 22, be between bonding agent 221, spherical scattering particles 222 and non-spherical scattering particles 222, to reflect, so can improve refractive index.
The spherical scattering particles 222 of plural number are to mix in bonding agent 221 with the non-spherical scattering particles 223 of plural number.Wherein, the material of spherical scattering particles 222 can be organic polymer or for inorganic material, for example be polymethacrylate (polymethyl methacrylate, PMMA), silicon dioxide (SiO

See also shown in the following table, the diffusion barrier 20 that is present embodiment carries out mist degree (Haze) result of experiment according to examination criteria JIS K7105:
| Production firm | Model | Mist degree (%) |
| KEIWA | BS04 | 87.35 |
| KIMOTO | 100GM3 | 87.21 |
| TSUJIDEN | D121U | 86.06 |
| The present invention | 88.06 |
By the result in the table as can be known, the mist degree of the diffusion barrier 20 of present embodiment is the mist degree greater than the diffusion barrier of other manufacturers.That is to say, the diffusion barrier 20 of present embodiment, owing to have spherical scattering particles 222 and non-spherical scattering particles 223 in the diffusion layer 22, so can reach preferable scattering and light diffusion effect.
