Title:
SOLID ELECTROLYTE AND DISPLAY ELEMENT USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2007/058046
Kind Code:
A1
Abstract:
This invention provides a solid electrolyte and a display element using the solid electrolyte
between counter electrodes. In recent years, for example, an improvement in
operating speed of a personal computer and spreading of a network infrastructure have
lead to an increase in the opportunity for inspecting electronic data information. A
display method utilizing dissolution precipitation of a metal salt such as a
silver salt in an electrolyte between counter electrodes in the display element is
known as means for inspecting such electronic data information. In the prior art,
the electrolyte between the counter electrodes in the display element contains an
organic solvent, and, thus, the prior art is disadvantageous in that storage for
a long period of time under a high temperature environment causes penetration of
the organic solvent into a sealing agent in the display element and volatilization of
the organic solvent, which cause a change in the composition of the electrolyte, resulting
in problems such as a variation in display function. The above problems could
have been solved, for example, by using, as the electrolyte between the counter
electrodes in the display element, a solid electrolyte comprising a room-temperature
molten salt of a silver salt, filler particles and a water-soluble polymer compound
substantially without containing an organic solvent.
