Electrochromic display device with a elektrolytimpraegnierten the separating element and a method for improving the electrolyte - receptivity of the separating element

摘要

PURPOSE:To secure the background effective to the display for the anti-heat/impact device and thus to increase the contrast by holding the pigment layer onto the porous film via the resin and using the layer as the impregnation layer after the electrolysis. CONSTITUTION:For the impregnation layer, pigment layer 17 of 10-30mum thick is formed on porous film 16 composed of the Teflon filter or the like by coating the solution of the powder of titanium sulfide, barium sulfate, etc. Then laminate resin layer 18 is formed on layer 17 to prevent detachment of the pigment. The film is then soaked into the surface active agent of the fluorine group to receive burning or the radiation irradiation, thus obtaining lyophilic porous film 19 which is to be the impregnation layer later. Then 1st and 2nd impregnation layers 19 and 13 doubling the background layer are held between glass substrate 6 on which transparent electrode 8 and display electrode 7 are formed and dish-shaped substrate 15 on which opposite electrode 14 is formed with impregnation of the electrolyte and formation of the bubble chamber and others. Thus, a display unit can be obtained, featuring a sufficient optical density, the background effective for the display and a high anti-heat/impact property.
