Description of the Invention: [Technical Field] The present invention relates to an organic electroluminescence display panel, and more particularly to an organic electroluminescence display panel having a moisture barrier and/or oxygen-incorporating structure. [Prior Art] In recent years, flat panel displays have been trending toward 1% brightness, flatness, thinness, and energy saving. In view of this, organic electroluminescent (〇EL) display devices have become the most desirable direction in the optoelectronic industry. One. The organic electroluminescent display device utilizes the self-luminous properties of organic functional materials to achieve a display effect, and can be classified into a small molecule organic electroluminescent display device according to the molecular weight of the organic functional material (small molecule). OLED, SM-OLED) and polymer light-emitting display (PLED) are two major categories. The organic electroluminescence display device is composed of organic electroluminescence elements, which is the purpose of full colorization. At present, the full colorization technology mainly used in organic electroluminescence display devices can be divided into three types. , G, B: The primary colors are the "three primary color luminescent layer method" of the independent illuminating elements. The first plant uses blue materials with red, green organic phosphors or white light to match a, green and blue organic luminescent bodies. The "color conversion structure" of the various colors is generated. The third type is the "color filter method" in which the white light-emitting layer is matched with the color filter. The technique of the color conversion structure method is taken as an example, as shown in FIG. The 1270333 full-color organic electroluminescent display panel 1 comprises an organic electroluminescent device 10, a flat layer 1 color conversion layer 12 and a glass substrate 13; the color conversion layer 12 is disposed on the glass substrate 13, a flat layer 11 is provided on the color conversion layer 12, and the organic electroluminescence element 10 is provided on the flat layer 11. The color conversion layer 12 has a plurality of filters and a plurality of color conversion films, and the flat layer 11 is for flattening the color conversion layer, and the organic electroluminescent device 10 has a first electrode 101 and an organic function. The layer 102 and a second electrode 103 are sequentially disposed on the flat layer 11. The principle of operation is that when a current is applied to the electrodes, the holes and electrons are recombined in the organic functional layer 102 to generate excitons. The organic functional layer 102 can generate a white light according to the characteristics of the material, such as a white light material, and convert the white light emitted by the organic electroluminescent device 10 into the three primary colors required for the full color by the color conversion layer 12, a blue light, a green light. And red light. Since the organic electroluminescent device 10 is very sensitive to moisture and/or oxygen, to ensure the service life of the organic electroluminescent device 10, as shown in FIG. 1, the process of the organic electroluminescent display panel 1 further includes a packaging process. A package 14 is adhered to the flat layer 11 by an ultraviolet curing adhesive 15 to form a sealed space to protect the organic electroluminescent device 10 from moisture and/or oxygen; however, it is known. In terms of structure, since the flat layer 11 is still partially exposed outside the sealed space, a pipe in which moisture and/or oxygen intrude is provided, and there is a concern that the organic electroluminescent element 10 is destroyed. Because of this, how to provide an organic electroluminescent display panel that effectively isolates moisture and/or oxygen intrusion is one of the important lessons of the current flat panel display 1270333.

As described above, in the embodiment, the barrier layer 4A may include a first barrier layer 417. And a second barrier layer 418. The package unit 42 is coupled to the substrate 4 to form a sealed space 43. The organic electroluminescent element 41 is located in the sealed space 43 and at least a portion of the sealing layer 42 is coupled to the side of the flat layer 412. (as shown in ^6). As described above, the package unit 42 can be attached to the substrate 4 by a cover 42ι and a second adhesive 422, or with a protective layer. In this embodiment, the substrate 4, the organic electroluminescent device 4, the modulating layer 411, the flat layer 412' barrier layer 416, the first electrode organic functional layer 4 Η * the second electrode 415 and the package unit 42 The materials, properties, and arrangement are the same as those of the first embodiment, and therefore will not be described here. According to the preferred embodiment of the present invention, the organic electroluminescent light 13 1270333 panel will comprise an optical modulation layer and a flat; the device is disposed between the package unit and the substrate; shape: excitation light element In the embodiment, the organic electroluminescent display surface of the embodiment has a flat layer structure outside the package unit, and the pattern is formed in the shape of the blank. In addition, the side layer of the flat layer can be combined with the package unit. The closed space is connected, so that the water vapor and/or the κι-part and the material of the pipeline can be effectively blocked. In addition, the damaging organic function can include at least the structure of the obstruction unit and the panel is more layer-blocking moisture. And/or the oxygen is covered by the early use, and the barrier is used to effectively reduce the moisture/oxygen intrusion into the machine early: the possibility of entering the screen, and increasing the organic electroluminescence excitation light to show the surface of the surface is only an example, Not a restrictive one. ::: The spirit and material of the present invention' (4) It is carried out: (4) It is not included in the scope of the patent application.
