Abstract
The present invention has as its subject an electrochromic pane including two glass sheets (1, 2), each coated with a transparent electrically conducting film (3, 4) and separated by an electrode of electrochromic material (5), an electrolyte (6) and a counter-electrode (7). The electrically conducting films (3, 4) are, on the one hand, connected by current supply leads (8, 9) to an electrical supply system generating a potential difference (U.sub.1) according to a desired modification to the coloration of the electrochromic material and, on the other hand, are connected to each other at least at a portion of their periphery by an electrically conducting material (11).
