PURPOSE:To prevent the deterioration of light emitting characteristic due to the moisture to prolong the lifetime of an element by containing at least one kind of super water repellent material in a sealing layer to be provided outside of a structural product, in which the organic light emitting material is pinched between a pair of electrodes. CONSTITUTION:A structural product 10, in which the organic light emitting material 3 is pinched between a pair of translucent electrodes, of which one electrode is made of the transparent or translucent material, for example, between a positive electrode 2 made of thin film of Au and a negative electrode 4 made of thin film of lithium, is formed on a transparent substrate 1 such as glass. A sealing layer 5, which contains the super water repellent material such as graphite fluoride at 80 deg. or more of contact degree with the water, is arranged outside of the structural product 10. Deterioration of the light emitting characteristic due to the moisture is thereby prevented to maintain the stabilized light emitting characteristic over a long time. |
