NOVELTY - The method involves coating macromolecular dispersed liquid crystal on a transparent conductive film to set up an illuminance sensor in a glass. A macromolecular dispersed liquid crystal composite film is formed and arranged with another transparent conductive film. A conductivity disperse particle composite film is formed using a conductivity disperse particle. A disperse particle back to back display device is formed with the conductivity disperse particle composite film. Another glass is arranged on a side of a membranous polymers dispersion LCD device.    USE - Method for manufacturing a solar blind structure for maintaining a dark state in an indoor.    ADVANTAGE - The method enables overlapping the macromolecular dispersed LCD device and the disperse particle in a solar blind structure so as to prevent seeing of an opposite side of a smart glass using property of the disperse particle back to back display device and block sunlight flowed into an interior of an indoor, so that dark state of the indoor can be efficiently maintained. The method enables controlling an on/off state of the conductive thin films in the macromolecular dispersed LCD device or disperse particle back to back display device using sensing result of the illuminance sensor so as to improve convenience of a user. The method enables making the conductive thin films using zinc-oxide and indium-tin-oxide so as to reduce fabrication cost of the solar blind structure. The method enables arranging an UV control film on the conductive films so as to prevent service life of the conductive films from shortened due to sunlight.    DETAILED DESCRIPTION - The glasses are soda lime glass, base iron glass, non-alkali glass, tempered glass or pasteboard, where the pasteboard is polymethyl methacrylate board or polycarbonate board. The glasses are coated with low refraction oxide and high-refractive oxide, where the high-refractive oxide comprises niobium pentoxide, titanium tri-oxide, tantalum pent-oxide or zirconium dioxide, and the low refraction oxide comprises silicon dioxide, magnesium fluoride, barium fluoride or aluminum fluoride. The conductive thin films are made of indium-tin-oxide or zinc-oxide, aluminum, gallium, indium or boron. The conductive thin films are arranged with a base film e.g. poly-ethylene terephthalate film, cobalt phosphide film, cyclo olefinecopolymer film, polyethylene naphthalate film or polyethersulfone film. The illuminance sensor is cadmium sulfide sensor, cadmium selenide sensor, lead sulfide sensor or lead selenide sensor.
