Abstract

PURPOSE:To provide the functions of reflection plates, to increase the speed of response and to permit multiplexing by mixing pigments and polytetrafluoroethylene or its deriv. with a specific solid electrolyte and molding the mixture under pressure. CONSTITUTION:Specific materials such as paratoluene sulfonic acid, poly-acids of phosphoric acid and tungsten oxide, lithium hydrazine sulfate or the like are used as the solid electrolyte for an electrochromic display. White pigments such as titanium oxide are added to the powder of such specific electrolyte in order to provide reflecting property thereto and further the polytetrafluoroethylene or its deriv. is compounded therewith as a binder at 1-5wt%. The mixture is molded under pressure to a sheet shape. The solid electrolyte of high strength is produced by the addition of the binder and since the electrolyte has reflecting property, the electrochromic display which does not require any reflection plate is obtained.

るものであった。Recently, electrochromic display devices using solid electrolytes have attracted attention. This is because the liquid snow melts that have been used so far have disadvantages such as unavoidable side reactions, insufficient longevity, and inability to perform multiplex (multi-digit behavior). When using a solid electrolyte, the reflection 111
Although it is conceivable that the solid electrolyte itself be provided with a white pigment, it is preferable to mix a white pigment into the solid electrolyte itself to give it reflective lateral ability. However, when a white pigment is mixed into a solid electrolyte and pressure molded, the molded product is brittle and poses a practical problem.

この発明は、こうした問題点を解決するものである。This invention solves these problems.

つぎに本発明について説明する。Next, the present invention will be explained.

ミック表示用の電解質として用いる。The solid electrolyte is further mixed with polytetrafluoroethylene and its derivatives. This serves as a binder during pressure molding later. This polytetrafluoroethylene is an extremely stable substance and will not react with the solid electrolyte even if it is mixed into it. There is no particular restriction on the lower limit, and the maximum limit is 5゛0Wt.
It is possible to mix up to -, but if it is too large, the proportion of electrolyte will decrease and there is a risk that its function will deteriorate. Therefore, in general, a range of 1 to 5 sounds is appropriate. This polytetrafluoroethylene is a white powder, and its mixing will not impair the function of the reflector.The solid electrolyte mixed with pigment and polytetrafluoroethylene is pressure-molded to form an electra. Used as an electrolyte for four-mic display.
