Abstract
An optical element comprises a first electrode; a second electrode partially including insulating areas; a seal frame member located between the first electrode and the second electrode; an electrolyte layer that fills a space defined by the first substrate, the second substrate, and the seal frame member; a first connection electrode disposed outside the seal frame member on the surface of the first substrate facing the second substrate; and a second connection electrode disposed outside the seal frame member on the surface of the second substrate facing the first substrate, wherein, in an area surrounded by the seal frame member, a proportion of the insulating areas of the second electrode included in an unit area relatively close to the first connection electrode is higher than that included in an unit area positioned in the middle of the seal frame member.
