Among them, the organic electroluminescent display device has the advantages of being thin, flexible, portable, full color, high brightness, power saving, wide viewing angle and high response speed. Classified by driving method, the organic electroluminescent display device can be divided into a main active matrix type and a passive matrix type. Among them, although the active matrix type organic electroluminescence display device has a better display effect, the manufacturing cost is higher than that of the passive matrix type organic electroluminescence display device. As shown in FIG. 1 , a passive organic electroluminescent panel 1 of the prior art comprises a substrate n, and a first electrode layer 12, a halogen defining layer 13 and a cathode blocking layer are sequentially formed on the substrate u. 14. An organic light emitting layer 15 and a second electrode layer 16. * As shown in FIG. 2, in the production of the organic electroluminescent panel, the first patterned electrode layer 12 is deposited to form a plurality of first electrodes i2i on the substrate 11. At this time, the first electrode 121 is along the edge. One row of the substrate η is arranged in the direction of 200847836. Then, an insulating material is deposited and patterned to form a gate-like halogen-defining layer 13 formed on the first electrode layer 12, thereby defining a plurality of light-emitting regions. Thereafter, a negative photoresist material is deposited and patterned to form a cathode barrier layer 14 over the individual definition layers 13 of the columns. Thereafter, an organic material is deposited to form the organic light-emitting layer 15, and a metal is deposited to form a second electrode layer 16, and the second electrode layer 16 has a plurality of second electrodes 161. By the height of the cathode barrier layer 14, the conduction of the second electrodes 161 in the row direction can be blocked. The first electrode 121, the organic light-emitting layer 15 and the second electrode 161 of each of the light-emitting regions constitute an organic light-emitting diode (OLED) element, wherein the first electrode 121 and the second electrode 161 are respectively used as organic light-emitting diode elements. Anode and cathode. Generally, when an organic light emitting diode element is applied to a display, the display is referred to as an organic electroluminescent display. A driving circuit is connected to the first electrode 121 of each row and the second electrode 161 of each column, and provides a potential difference between the two electrode layers 12, 16 to drive the organic light-emitting layer 15 of each of the light-emitting regions to emit light. In addition, the traces (not shown) of the first electrode layer 12 and the second electrode layer 16 connected to the external circuit may be formed through deposition and patterning steps before being formed on the first electrode layer 12. On the substrate 11. Among them, the material of the traces may be metal, and patterning the traces also requires a mask process. However, the foregoing fabrication method requires a total of four mask processes to separately pattern the second metal layer, the first electrode 12, the halogen defining layer 13, and the cathode barrier layer 14, that is, more processing steps are required. Therefore, if the mask process required for 200820083636 can be reduced, the manufacturing cost can be reduced. Therefore, how to provide a passive matrix type organic electroluminescence display panel and a method for fabricating the same, which avoids the above problems and improves the above-mentioned aspects, is an important subject.

Cathode barrier layer . Compared with the W technology, the manufacturing method of the organic electroluminescent display panel of the present invention is a method of manufacturing a state-of-the-art mask, which can effectively save production costs. In addition, the row of the partitions has a beveled surface and is provided with an electrode. The edge ' makes the first electrode less likely to be perforated and the disk first to the electrode causes the cone: t, the material of the auxiliary electrode layer is metal or composite gold|, so the electric separation portion and the column separation portion can have good The light-shielding property makes it possible to have a good contrast ratio. In this way, the organic electroluminescent display panel can even save the material cost without using a polarizing plate to increase the contrast ratio. [Embodiment] Hereinafter, a 200847836 moving moment type organic electroluminescence display panel and a method of fabricating the same according to the present invention will be described with reference to the related drawings. 3 to 7 are a flow chart for fabricating a method for fabricating an organic electric panel X two display panel 2 according to a preferred embodiment of the present invention. First, in conjunction with FIG. 3, a first electrode layer 22 is deposited and patterned to form a plurality of first electrodes 221 in the row direction of the earth plate 21. In this embodiment, the substrate 21 can be a glass substrate, a plastic substrate or a flexible substrate. The first electrode layer 22 can be sputtered or separated from: i〇n plating. The method is formed on the substrate U. Further, the material of the first electrode layer 22 may be a conductive metal oxide such as indium tin oxide (ITO), oxidized inscription (ΑΖ〇) or indium oxide (ι). In this step, a mask process is required. An auxiliary electrode layer 23 is deposited and patterned to form a plurality of rows of partitions 231, a plurality of columns of partitions 232, and a plurality of traces 233, as shown in Fig. 4A and Fig. 4B. The two rows of partitions 231 are respectively disposed between the adjacent first electrodes 221, and the adjacent row of partitions 231 have a gap s, and the row of partitions 232 are respectively disposed at the same The first private pole 221. Here, the gap s has a function of blocking the adjacent first electrode 221 such that the adjacent first electrode 221 is not turned on. The row dividing portion 231 and the column dividing portion 232 define a plurality of light emitting regions Α1' of the organic electroluminescent display panel, and the wiring portions 233 are disposed in one of the non-display regions of the organic electroluminescent display panel. (Figure 4Β). Thereby, the functions of the row separation portion 231 of the auxiliary electrode layer 23 and the column separation portion 232 are functions of a conventional halogen defining layer, and the organic electroluminescent display panel 2 can be divided into the light emitting regions A1. 11 of the auxiliary electrode layer 23 200847836 The wiring portion 233 is a conventional wiring metal layer 'Yes, + 2 2 can use the wiring portion 233 and the external electroluminescent display surface when patterning the auxiliary electrode layer 23 It is necessary to use, and, in the present embodiment, the auxiliary electrode layer 23 is forced, and the cover η metal system may be a gasification short _, Mingbi feather: Γ or a combination thereof. The auxiliary electrode layer 23 is made of a metal, and the bismuth-defined layer of the bismuth has a high conductivity, ^ ^ ^ Therefore, the auxiliary electrode θ 23 can be used as a data line on the display panel of the organic electroluminescent display panel (5). Resisting! A few 'to make the drive voltage drop, can save energy. In addition, since the material of the auxiliary electrode layer 23 is metal or a composite metal, the light is less likely to penetrate, and thus the row separation portion 231 and the column separation portion 232 can have good light shielding properties, thereby improving organic electricity. The contrast of the light display panel 2 is excited. In this way, the organic electroluminescent display panel 2 of the present invention can even increase the contrast without using a polarizing plate, and has the effect of saving material cost. In addition, in the embodiment, the row dividing portions 231 have a slope 231a in the column direction, which covers the edge of the first electrode 221 to the substrate 21, and the slope 231a of the row partition 231. , formed by the process of engraving. Since the edge of the first electrode 221 is covered by the slope 231a of the row of the etched portions 231, when the organic electroluminescence light is inadvertently pressed, the first electrode 221 is not easily pressed by the row partition 231. The perforation is generated, causing the first electrode 221 to be short-circuited with the first (not shown).槌 Layer Please refer to Figure 5 to form a cathode barrier layer 24 on the auxiliary power 12 200847836 23 . In this embodiment, the cathode barrier layer 24 is disposed on the column spacers 232, and the material of the cathode barrier layer 24 may be a negative photoresist. Here, a further mask process must be used to form the cathode barrier layer 24. Next, referring to FIG. 6, an organic light-emitting layer 25 is deposited on the first electrode layer 22, and the organic light-emitting layer 25 is disposed on the first electrode 221 corresponding to the light-emitting area A1. The organic light-emitting layer 25 may be a one-stack structure comprising a hole transport layer, a light-emitting layer and an electron transport layer (not shown). Then, as shown in FIG. 7, a second electrode layer 26 is deposited on the organic light-emitting layer 25, and a plurality of second electrodes 261 are formed in the corresponding light-emitting region A1, and the trace portions 233 are connected to the first Electrode layer 22 and second electrode layer 26. In this embodiment, the material of the second electrode layer 26 is selected from at least one of aluminum, stellite, bismuth, indium, tin, fierce, silver, gold, and magnesium-containing alloys - thereby, an organic electroluminescent display The panel 2 can be electrically connected to an external circuit (not shown) by the wiring portions 233. It can be seen from the above that the method for fabricating the organic electroluminescent display panel 2 of the present invention can replace the conventional pixel defining layer with the auxiliary electrode layer 23 and the gap S of the adjacent two rows of partitions. The second gold is the function of the layer. Therefore, only three mask processes are required to separately pattern the first electrode layer 22, the auxiliary electrode layer 23, and the cathode barrier layer 24. It can be seen that the manufacturing method of the organic electroluminescent display panel 2 of the present invention can save a mask process, and can effectively save the manufacturing cost. Next, please refer to FIG. 7 , which is an organic power 13 according to a preferred embodiment of the present invention. The 200847836 excitation light display panel 2 includes a substrate 21 , a first electrode layer 22 , an auxiliary electrode layer 23 , an organic light emitting layer 25 , and a The second electrode layer 26 and a cathode barrier layer 24. However, the structure and structure of the substrate 21, the first electrode layer 22, the auxiliary electrode layer 23, the organic light-emitting layer 25, the second electrode layer 26, and the cathode barrier layer 24 are the substrate 21 and the first electrode layer in the foregoing embodiments. 22, the auxiliary electrode layer 23, the organic light-emitting layer 25, the second electrode layer 26, and the cathode barrier layer 24 are the same, and the same reference numerals are used herein. As described above, the organic electroluminescent display panel and the method of fabricating the same according to the present invention utilize a three-mask process to separately pattern the first electrode layer, the auxiliary electrode layer and the cathode barrier layer. Compared with the conventional technology, the manufacturing method of the organic electroluminescent display panel of the present invention can save a mask process, and the production cost can be effectively saved. Further, since the row partitions have a beveled arrangement, the first electrode is less likely to be perforated adjacent to the periphery of the row partition to cause a short circuit. Further, since the material of the auxiliary electrode layer is metal or a composite metal, the row partitions and the column spacers have good light shielding properties, so that the organic electroluminescent display panel has a good contrast. In this way, the organic electroluminescent display panel of the present invention can even increase the contrast by using a polarizing plate, and has the effect of saving material cost.
