Electrochromic mirror

Abstract

An electrochromic mirror includes an electrically conductive reflective film capable of reflecting light that is incident thereto and having electrical conductivity in which plural fine penetration holes are formed, an electrochromic film that is provided at a side of the electrically conductive reflective film at which the light is incident and reflected, an electrically conductive film that is provided at a side of the electrically conductive reflective film that is opposite from the electrochromic film, and an electrolytic solution that contains lithium ions and is enclosed between the electrically conductive film and the electrically conductive reflective film. The plural penetration holes formed in the electrically conductive reflective film penetrate in a thickness direction thereof, and a ratio between a distance between respective centers of the penetration holes and an inner peripheral diameter dimension of the penetration holes is 7 or more.

Description

technical field [0001] The present invention relates to an electrochromic mirror used for, for example, a rearview outer mirror or a rearview inner mirror of a vehicle and capable of changing reflectance by applying a voltage. Background technique [0002] In the specification of U.S. Patent No. 3,844,636, an electrochromic mirror is disclosed, wherein the electrochromic film is colored due to the reduction reaction of the electrochromic film, thereby reducing the transmittance of reflected light, resulting in light loss. Reduced reflectivity. [0003] In the structure disclosed in the specification of U.S. Patent No. 3,844,636, a plurality of holes are formed in the conductive reflective film, but simply forming these holes may lower the reflectance or cause light diffraction and scattering. , so that a clear reflection image cannot be obtained. [0004] Therefore, there is a need for an electrochromic mirror that can prevent or effectively suppress the occurrence of prob...
