Disclosed is an electrochromic device including at least one display region and at least one non-display region, which are separated from each other, the electrochromic device including a first substrate, a first electrode, an electrochromic layer, an electrolyte layer, optionally an ion storage layer, a second electrode, and a second substrate, which are sequentially formed, wherein the ion storage layer and/or the second electrode are patterned so as to prevent the ion storage layer and/or the second electrode from existing in part or all of said at least one display region; and a display device including the electrochromic device. In the electrochromic device, only the second substrate and electrolyte layer are located between the observer and the electrochromic layer, so that it is possible to prevent a contrast ratio from being degraded due to the ion storage layer and/or second electrode.
