Abstract

A reflection mirror using a liquid crystal cell is disclosed. A first thin film consisting of one of magnesium difluoride, silicon dioxide, silicon monoxide or titanium dioxide is formed on a glass substrate supporting the liquid crystal cell and a thin aluminum film is formed on the first thin film as a reflection mirror layer. Adhesiveness of the thin aluminum film to the glass substrate is strengthened by the first thin film. A second thin film is formed on the thin aluminum film to protect the same from being hurt. The reflection mirror may be used as a dazzle-free reflection mirror of an automotive vehicle.
