Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
129 words
A variable light transmittance glass board which is functional as an electrochromic cell and which comprises: two transparent glass substrates each of which is laid with a transparent electrode film and which are arranged such that the two transparent electrode films are held opposite to and spaced from each other; a first electrochromic layer which comprises tungsten trioxide and is formed on one of the two transparent electrode films; a second electrochromic layer which comprises Prussian blue and is formed on the other of the two electrode films; and an electrolyte liquid which fills up the space remaining between the two transparent electrode films, said electrolyte liquid being a solution of a supporting electrolyte in an organic polar solvent to which 0.2 to 3.0 wt% of water is added.
