Patent ID: 8531754

Claim:
An electrochromic display element comprising: a display substrate, at least one display electrode, a counter electrode, a counter substrate, at least one electrochromic layer in contact with the display electrode, and an electrolyte layer between the electrochromic layer and the counter electrode, wherein the electrolyte layer contains a matrix resin having a three-dimensionally crosslinked structure and a mixture of a liquid crystal compound and an electrolyte, wherein a crystalline electrolyte including the mixture of the liquid crystal compound and the electrolyte is dispersed as a continuous phase in the matrix resin, and the electrolyte layer has a polymer network liquid crystal structure formed from the crystalline electrolyte dispersed as the continuous phase in the matrix resin, and wherein the electrolyte layer is formed by forming the matrix resin through the polymerization reaction of the mixture of polymerizable monomer or oligomer of the matrix resin and the liquid crystal electrolyte while phase-separating the matrix resin from the liquid crystal compound.
