Electrochromatic glass

The invention discloses ectrochromatic glass which comprises two pieces of glass with indium tin oxide (ITO) electrodes on the surfaces. The indium tin oxide electrodes of the glass are opposite to each other and a filling area is reserved between the electrodes. The edges of the electrodes are glued by using filling glue. A bistable state liquid crystal is poured in the filling area and reversed under drive of voltage. The ectrochromatic glass provided by the invention has the beneficial effects that for the ectrochromatic glass, the ITO electrodes are formed on one surface of the glass, the two pieces of glass with the ITO electrodes are glued and the filling area is reserved between the electrodes, and then the bistable state liquid crystal is poured in the filling area. When the electrodes are applied with voltage, the liquid crystal is reversed and switched between transparency and non-transparency so as to change the transmissivity and the transparency. Furthermore, when the state is triggered once, power can be cut off, and the liquid crystal is maintained in a special reversing state so as to save energy sources. In addition, a line can be further formed on the ITO electrodes, so that the ectrochromatic glass is partially transparent and partially non-transparent, therefore, the light transmittance can be further improved.
