<p>The present invention provides a smart window comprising: an organic light emitting element having first and second electrodes, which correspond to each other, and a light emitting layer, which is arranged between the first and second electrodes and includes an organic light emitting material; and an electrochromic element having third and fourth electrodes, which correspond to each other, and an electrochromic layer, which is arranged between the third and fourth electrodes and includes an electrochromic material, wherein the organic light emitting element and the electrochromic element are bonded to each other, the first electrode is formed of a transparent electrode or a semitransparent electrode, and the second electrode is formed of a high reflective semitransparent electrode. In the smart window according to the present invention, one of electrodes of the organic light emitting element is formed of the high reflective semitransparent electrode, thereby enhancing optical efficiency and contrast without degrading transmittance.</p> |
