Abstract

PURPOSE: To prolong service life and yet provide low cost and mass productivity and enhance grade by providing a reference electrode on the non-transparent porous plate to be inserted into the display cell.
CONSTITUTION: A transparent display substrate 11 and a tray form back substrate 1 are bonded by means of adhesive agents 8, 8' to form a display cell case. Transparent display electrodes 10 are formed on the substrate 11 and further inorganic solid electrochromic materials films 9 thereon. A back electrode 2 is formed on the substrate 1. A porous plate 13 provided with a reference electrode 14 such as of gold thin film is inserted together with glass fiber filter paper 4, 4' in this cell in order to provide a white color which becomes the background of the display. The electrode 14 is connected to the conductive part 12 connecting to the outside, by way of a conductive buffer body 15 such as of carbon fiber. Electrolytes 6, 6' are injected into the spaces of the cell.
