Abstract
The invention provides a transparent electrode barrier layer between the metal oxide electrodes and electrochromic layers thereon in an electrochromic display in which coloration of the electrochromic layers is attributed to the incorporation of protons therein under an applied electrical potential. The electrode barrier layer minimizes the destructive reaction between the metal oxide electrodes and hydrogen from colored electrochromic layers. Display life is thereby substantially improved.
