INSTRUCTION DESCRIPTION (1) 5 - 1 Field of the Invention: The present invention relates to an organic electro-luminescence device (OEL), and more particularly to an organic electro-cooled light (0EL) having a reactive protective layer. ) Component structure. 5 - 2 invention background: In general, a piece, for example, an organic Diode; 0LED) inserts an organic sub-injection from the cathode electrode. The hole will be in the organic line. Such electro-cold light forms an organic layer. Therefore, for various components and instruments, Electro-Luminescent (EL) light-emitting diodes (Organic Light Emitting or similar) are constructed in a pair of yin and yang electrode layers. (Laminated organic layers) ° When electricity and holes are injected from the anode electrode to the organic layer, the electrons and the layers are combined with each other, causing the light-emitting elements to emit light having high brightness and high contrast characteristics, and the material is radiated. Light has the advantage of multi-color. In the poor industry, electric luminescence components can be applied to the display of the emission light source components. 〇 So far, organic electric cold clamps; organic luminescence components are finished ώ = some defects still exist Overcome. Characteristics (that is, luminescence strong) After 1 package, in the initial stage of use, its luminescence causes the luminescence property to be inferior = = a large deterioration phenomenon with time. ' M t due to the internal structure of the organic luminescence element Residual

1281361 V. INSTRUCTIONS (2) caused by moisture and water intrusion from the outside of the component. Organic electric luminescence element - The organic film inside is deliquescent due to the adsorption of moisture, and the metal electrode is degraded by the oxidation of moisture and oxygen. On the other hand, when an external voltage is applied to the electrodes of the organic electroluminescent element to drive the organic electroluminescent element to emit light for a while, the organic electroluminescent element generates heat. In this way, the speed of deterioration is accelerated, thereby causing dark spots (D a r k s ρ 〇 t) on the organic electric luminescence element. As oxidation and deliquescence progress, the dark spots continue to expand, even jeopardizing the entire illuminating element. As described above, it is necessary to effectively reduce the moisture remaining in the internal residual portion of the organic electric luminescence element and the moisture intruded outside the element to prevent generation of dark spots. Nowadays, a cover structure (h e r m e t i c s e a 1) containing a water absorbing agent is disposed outside the organic electroluminescent element to achieve long-term stability and life improvement, and the material of the cover is usually metal or glass. Referring to the first figure, the conventional organic electro-optic device 100 includes: a substrate 110, and an organic electric cooling element 1 2 0 is connected under the substrate 11 0; a cover 1 3 0, a bottom of the cover structure 1 3 0 There is a water absorbing agent 140, wherein the cover 130 has a cover edge 150, and the cover edge 150 is connected to the substrate 11 by an adhesive 160. However, the cover is as described above. There are still some problems with the structure. Since a considerable amount of space must be removed in the structure for the water absorbing agent, there is a space between the capping structure and the organic electroluminescent element, and the air containing oxygen and oxygen is still contained in the gap. Furthermore, the conventional organic electric luminescence element

Page 7 1281361 V. INSTRUCTIONS (3) The adhesive used in the package structure also has water permeability (about 〇 · 2%). Therefore, as the use time increases, the outside air containing moisture and oxygen still penetrates into the voids inside the package structure via the adhesive. On the other hand, the electron conduction state of the organic electroluminescent element 120 should ideally only terminate between the layers inside the organic electroluminescent element 120, however, actually, some electrons are leaked through the cathode layer. Leakage current problem. In this regard, the conventional method is to add an inorganic passivation layer on the uppermost structure of the organic electroluminescent element 120 to prevent the above problem. However, due to the high hardness of the inorganic layer material, deposition is performed. system

After the process, the film bonding surface between the organic layer of the organic electroluminescent element i 2 and the cathode thereof is partially separated by the action of stress, so that the contact surface is deteriorated, thereby causing the efficiency of the sub-injection to be deteriorated, further causing the light emission. The deterioration of the light-emitting characteristics of the element. In view of the above various reasons, we need a new structure of an organic electric luminescence element to improve the illuminating characteristics and service life of the organic luminescence element. 5 - 3 Purpose and overview of the invention:
