1. An electrochromic pane comprising:
- first and second glass sheets, each coated with a transparent electrically conducting film;
a first electrode of electrochromic material formed on the first glass sheet;
a counter-electrode of electrochromic material formed on the second glass sheet;
an electrolyte formed between the first electrode and the counter-electrode;
electrical supply leads for connecting the electrically conducting films to an electrical supply system generating a potential difference (U1) as a function of a desired modification of a coloration state of at least one of the first electrode and the counter-electrode; and
an electron conducting material connecting the electrically conducting films to each other at least at a portion of their periphery for creating a controlled short-circuit between the electrically conducting films, wherein the electron conducting material is filled between the first and second glass sheets by contacting the conducting films.

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 (U1) 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).
