The present invention provides an all solid state type reflection light control electrochromic element and a light control member that uses this element, relates to an all solid state type reflection light control electrochromic element, which is a magnesium/titanium alloy reflection type light control element in which a multilayer thin film is formed on a transparent substrate, wherein at least a transparent conductive film layer, an ion storage layer, a solid electrolyte layer, a catalyst layer, and a reflection light control layer employing a magnesium/titanium alloy thin film are formed on the substrate; and a light control member which is incorporated with this reflection light control electrochromic element, and the present invention allows a reflection light control electrochromic element, which has a novel multilayer structure that is colorless when transparent and can be switched in a short time over a wide area, as well as a light control member incorporated with this element to be provided.

All solid state type reflection light control electrochromic element employing magnesium/titanium alloy and light control member

A switchable mirror element includes a switchable layer having a chromic property enabling the switchable layer to be reversibly changed from a transparent state by hydrogenation and a mirror state by dehydrogenation, and a catalytic layer disposed on the switchable layer and configured to promote hydrogenation or dehydrogenation in the switchable layer. The switchable layer includes an alloy of one or more metals from calcium, strontium, and barium, and magnesium.
