Abstract
A luminescent device that has at least an anode layer (), a cathode layer (), and an organic EL layer () formed on a transparent substrate (), and has the organic EL layer () placed between the anode layer () and the cathode layer () is disclosed. In this luminescent device, notches () are formed at the rim portion of the transparent substrate, and patterning is performed on the transparent substrate () so that the organic EL layer () avoids the notches (), and the anode layer () and the cathode layer () overlap the organic EL layer (). Part of the anode layer () and part of the cathode layer () are exposed through the respective notches () of the transparent substrate ().
