Abstract
The present application relates to an electrochromic device. In one aspect, the electrochromic device includes an electrochromic element including a first electrode, a second electrode, an electrochromic layer, an ion storage layer and the second electrode. The electrochromic device also includes controller configured to change a state of the electrochromic element to change to at least one of a first state having a first transmittance, a second state having a second transmittance, a third state having a third transmittance, or a fourth state having a fourth transmittance by applying power to the electrochromic element. When a first voltage is applied to the electrochromic element in a first state, the electrochromic element becomes the second state, and when the first voltage is applied to the electrochromic element in a fourth state, the electrochromic element becomes the third state.
