Abstract

Abstract Anti-glare EC mirror comprises a transparent glass substrate with ITO film, IrO x film, SnO 2 film, Ta 2 O 5 film, WO 3 film and Al film in the order written. Because of this layer arrangement, SnO 2 film insures an ample supply of water during the aging of IrO x film, thereby allowing the aging operation to be completed within a short period of time.
