Abstract
Electrochromic device including: first electrode; a first auxiliary electrode; a second electrode; a second auxiliary electrode having average distance of 100 mm or less with the first auxiliary electrode; an electrochromic layer; a solid electrolyte layer; and controlling unit configured to control to apply voltage according to a driving pattern that is at least one selected from the group consisting of a first driving pattern, a second driving pattern, and an initialization driving pattern, wherein the first driving pattern is a driving pattern configured to turn the electrochromic layer into first coloring state, the second driving pattern is a driving pattern configured to turn the first coloring state into a second coloring state that has coloring density lower than coloring density of the first coloring state, and the initialization driving pattern is driving pattern for forming an initial decolored state.
