BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an organic electroluminescent display device, and more particularly, to a structure of positive and negative short bars of a mother substrate and a method of manufacturing an organic electroluminescent display device using the same.

Recently, various flat panel displays have been developed to reduce weight and volume, which are disadvantages of cathode ray tubes. Such flat panel displays include liquid crystal displays (hereinafter referred to as "LCDs"), field emission displays (FEDs), plasma display panels (hereinafter referred to as PDPs), and electroluminescence. Nessence ("EL") display device, etc. There are active researches to improve the display quality of such a flat panel display device and attempt to enlarge the screen.

Among them, PDP is attracting attention as a display device which is light and small and is most advantageous for large screen because of its simple structure and manufacturing process. However, PDP has low luminous efficiency, low luminance and high power consumption. On the other hand, an active matrix LCD having a thin film transistor (TFT) as a switching element has a disadvantage in that it is difficult to make a large screen because of the semiconductor process, and power consumption is large due to the backlight unit. Optical elements such as a filter, a prism sheet, and a diffusion plate have a large optical loss and a narrow viewing angle.

On the other hand, EL devices are classified into inorganic EL devices and organic EL devices according to the material of the light emitting layer. The EL devices are self-luminous devices that emit light by themselves, and have a fast response speed and high luminous efficiency, luminance, and viewing angle. Inorganic EL devices have higher power consumption and higher luminance than organic EL devices, and cannot emit various colors of R, G, and B. On the other hand, the organic EL device is driven at a low DC voltage of several tens of volts, has a fast response speed, obtains high luminance, and emits various colors of R, G, and B, which is suitable for next-generation flat panel display devices. .

1 is a cross-sectional view showing one organic EL cell of a conventional organic EL display element, and FIG. 2 is a diagram for explaining the light emission principle of the organic EL display element.

The EL cell 3 shown in FIG. 1 includes an organic light emitting layer 10 formed between the first electrode (or anode electrode) 4 and the second electrode (or cathode electrode) 12, and the organic light emitting layer 10 ) Is provided with an electron injection layer 10a, an electron transport layer 10b, a light emitting layer 10c, a hole transport layer 10d, and a hole injection layer 10e.

When a voltage is applied between the first electrode 4 and the second electrode 12 of the EL cell 3, electrons generated from the second electrode 12 are transferred to the electron injection layer 10a as shown in FIG. 2. And holes toward the light emitting layer 10c through the electron transport layer 10b. Further, holes generated from the first electrode 4 move toward the light emitting layer 10c through the hole injection layer 10d and the hole transport layer 10d. . Accordingly, in the light emitting layer 10c, light is generated by collision and recombination of electrons and holes supplied from the electron transport layer 10b and the hole transport layer 10d, and the light is emitted to the outside through the first electrode 4. The image is displayed.

3 is a diagram illustrating an array region P1 and a vialay region P2 of a conventional mother substrate.

Referring to FIG. 3, an organic EL array including a plurality of EL cells is formed in the array region P1 to extend the display region A in which an image is realized when the organic light is emitted, and the organic EL array in the display region A. And a non-display area B in which the data lines 54 and the scan lines 55 are positioned, and the via region P2 is a positive electrode used for the aging process and the lighting test, which are stabilization processes of the organic EL device. Polar and negative short bars 53 and alignment marks (not shown) used in the scribing process are formed.

The positive and negative short bars 53 are connected to the data pads 56 connected to the data lines 54 of the non-display area B of the array area P1 and the scan pads connected to the scan lines 55. And 57 are electrically connected to each other. The positive and negative short bars 53 transmit voltages to the data pads 56 and the scan pads 57 of the array region P1 by being connected to the needle pins of the inspection equipment during the aging process and the lighting test. Do it.

The vialay region P2 in which the alignment marks (not shown) and the positive and negative short bars 53 are formed is removed during the scribing process.

The positive and negative short bars 53 have a line width d1 of about 2000 μm or more for contact with the needle pin of the inspection equipment, thereby increasing the vialay region P2 of the mother substrate. have.

For example, when 10 lines of organic EL arrays are formed on a mother substrate, the positive and negative short bars 53 occupy about 20 mm of the entire mother substrate. As described above, when the area occupied by the short bar is large, the proportion of the array area P1 of the mother substrate becomes smaller, thereby lowering the productivity of the organic EL display device.

In order to solve this problem, a structure in which the positive and negative short bars 53 are reduced as shown in FIG. 4 has been proposed.

However, although the mother substrate shown in FIG. 4 has an advantage of improving productivity, when the positive and negative short bar 53 line widths d2 of the vialay region P2 are reduced, the aging process and lighting are turned on. In the case of inspection, the space of contact with the needle pin of the inspection equipment is reduced so that the needle pin is in contact with the data pad 56 and the scan pad 57 of the array region P1 instead of the positive and negative short bars 53. Occurs.

As a result, scratches are generated on the data pad 56 and the scan pad 57 by the needle pins, and the EL cells directly connected to the data pad 56 or the scan pad 57 to which the needle pins are contacted are not. The luminance difference with the cell occurs.

In addition, since the needle pins are in contact with each of the short bars 53 formed to correspond to the respective organic EL arrays, a new inspection equipment must be manufactured every time an organic EL element having a different size is proposed, thereby increasing the manufacturing cost of the organic EL display element. The problem arises.
