可能なほど発色しない。 In the past, several proposals have been made regarding display bodies in which an inorganic electrochromic material and a liquid or solid electrolyte are laminated, but all of them are aimed at causing the inorganic electrochromic material to develop color using ions. Particularly when a liquid electrolyte is used, the color is developed with good contrast, but the disadvantage is that the life is short. Furthermore, when a solid electrolyte is used, the color does not develop to the extent that it is visible to the naked eye.

グ方法などが用いられる。 Coexistence refers to a state in which one material is doped into the other in the form of atoms, or exists in the form of molecules or small molecular aggregates. In order to realize such a coexistence state, a high temperature diffusion type inorganic electrochromic material that diffuses at high temperature and lead fluoride are simultaneously deposited in a vacuum using two sources, and depending on the material, a chemical vapor phase Growth methods, sputtering methods, etc. are used.
以下、本発明を実施例により説明する。 The present invention will be explained below with reference to Examples.

着された固体表示体である。 FIG. 1 shows a solid state display of the present invention produced by a vacuum deposition method, in which 1 is a bell gear, 2 is a vacuum chamber, 3 and 4 are vapor deposition source heaters, 5 is a substrate, and 6 is a vapor-deposited solid state display. It is.

できる。 Now, tungsten oxide and lead fluoride may be placed in the vapor deposition source heaters 3 and 4, respectively, and the vapor deposition rate may be controlled by the temperature of the heaters so that a constant mixing ratio is achieved. In order to decolor or change the color of the solid-state display produced in this way, it is basically sufficient to apply an electric signal, and it is also possible to use X-rays, ultraviolet rays, electron beams, etc.

用いることができる。 When a DC voltage is applied between the terminals 11 and 12, the color develops as shown in FIG. 3, and when the voltage is turned off, the color disappears. The DC voltage may be a few volts, and the color will develop even if the polarity is changed or an AC voltage is applied. Moreover, conventionally proposed solid-state electrochromic devices using inorganic electrochromic materials do not develop color in vacuum, but in the case of the present invention, color develops even in vacuum. The cause of this is not yet clear. Furthermore, the solid display of the present invention maintains its coloring state when more energy is applied, and can also be used as a storage medium.
