The contact hole is formed by the sputtering method, etc. Aluminium chromium and other gold film are filled with item 1 to 1 to form a photo-etching method. After forming the pattern drawing to make source-to-source wiring 7 and drain script 100 ▲ I 8, remove the η -a -S i between source < > drain by etching. Finally, due to the need, ^ 〆 1 1 I need to form a protective film with Si N and so on. 1 1 As described above, the short circuit t of the gate 2 and the drain 8 1 1 due to the impurities constitutes the reason that the sufficient resistive contact cannot be obtained due to the composition 1 and it occurs by the probability of a few PP m Pixels that do not work properly, that is, so-called I point defects.

The same on the pixel electrode connected to the pixel Part D melts the gate insulating film through the repair model The portion that the pixel electrode and the pixel electrode short-circuiting of adjacent pixels of the pixel of point defects. Example 8 Figure 16 shows Example 8 of the present invention. The structure of FIG. 16 is the same as that of Embodiment 7 except that the order of the manufacturing process of the gate electrode 2 and the pixel electrode 3 is replaced. That is, the island electrode 12 is formed on the pixel electrode 3. According to the present invention, point defects can be easily repaired, and the yield of the TFT array and the liquid crystal display device using the array during manufacturing can be improved. According to the invention, it is easy to repair point defects at the TFT array stage found during the manufacturing process. For the point defects found after becoming a liquid crystal display device, that is, when laser light must be incident from the pixel electrode side during repair, It can also be easily and surely repaired. In addition, the manufacturing process is exactly the same as the conventional method, only the model drawing is changed, and the project is not increased without increasing the cost.

Description of the invention (19) The light is cut off according to the C-C line shown in Figure 17 and then The D part on the pixel electrode 3 and the D part on the cape electrode 3 adjacent to all pixels are irradiated with laser light, and the quine electrode adjacent to the quinoline is short-circuited through the point defect repair wedge pattern 111. At this time, since the two-metal film of the dielectric 31 storing the storage capacitor, that is, the point defect repair pattern 111 and the island portion 12 are connected by laser, it can be easily and surely repaired. This is particularly effective when laser light is irradiated from the pixel electrode 3 side. In this embodiment, the configuration is to connect the left and right pixel electrodes, but it can also be used to connect the upper and lower pixel electrodes. According to this embodiment, in order to use the dot defect repair pattern 111 to short-circuit the pixel that is considered to be a dot defect to the adjacent pixel, the adjacent pixel electrode becomes the same potential, and the same display is made and it is not easy to think of a pseudo-dot defect , Thereby improving the yield of the TFT array. And because it is the same manufacturing method as the conventional technology, it only has to change its mold drawing, without increasing the number of projects and has the advantage of not increasing the cost. According to the present invention, the repair of the point defects found in the TFT array stage is self-evident. After the liquid crystal display device with the liquid crystal held between the TFT array substrate and the counter electrode substrate such as the transparent electrode and the color filter, that is The laser light incident from the pixel electrode side can also be repaired easily and surely. Example 1 0 FIG. 20 shows a partial cross-sectional view of a TFT array used in a display device according to Example 10 of the present invention. This embodiment 10 has the same structure as the embodiment 9 except that the order of the manufacturing processes of the gate and wiring 2 and the pixel electrode 3 is replaced. That is, a pixel electrode is formed on the point defect repairing pattern 111 by a dielectric 31 with a storage capacitor; 3, an island 12 is formed thereon. As mentioned above, the island section 12 can be applied to the Chinese National Standard (CNS) A4 specification (210X 297 mm) on this paper scale. . t. . --------- Full ------ lsτ ------ f (Please read the precautions on the back before filling out this page) A7 B7 Printed by the Employees ’Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs V.

A kind of liquid crystal display device, which is composed of a gate formed by a metal thin film and 2 6 paper size applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) 38183 -------- f -(Please read the precautions on the back before filling in this page), -a AS B8 C8 D8 6. Patent application gate wiring, gate green film, semiconductor layer, resistive contact layer, source and source wiring The thin-film transistors of the dipole and the printed pair are printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs and Transparency. The shape of the first prime electric film before the thinning is in the middle. The thin element of the nectar element should be bridged to show its gold. The system is matched with the filter of one of the fans, and the middle crystal ones are easy to pass over. When the formed liquid is placed, the aluminum plate is not equipped with the color plate or the special equipment. Please click on the display of the missing base and the lower part of the film to show the display of the molybdenum and the thin part showing the pole edge. In the case of electricity, there is a bridge layer, crystal emblem, tungsten, and polar crystals, which will be described as containing liquid gold, 15 electrohydraulic lines, and the titanium penetrating the liquid or its titanium. The first part of the special method is that some of them are based on the layer load, or the picture load is extremely elegant, and the second is set on the crystal and the film. Recorded as the record giant 14 Yuji gate is reset to repair the item with the edge of the liquid pole, and the connection and the repair and repair to be extremely electric insulation 擞 13 belong to 14 chromium 13 to 13 pole island shown The neighboring electricity is set as the prime electrode, and the terminal electrode is set as the first part. Su, the painting gates are surrounded by pseudo points. The engraving on the island encircles the picture board of the pre-installed Jingdian fan board is Fan Rong Fan's fan Fan Shu Fan Qiancheng's substrate with liquid element is connected to the above. The front part of the Legie is mainly dedicated to the specialty, special secondary, technical and secondary materials. The other shape is in the middle of the island. Please ask the department to melt it. Shendao Shengao is Shen. Shen, which is a kind of polar pole. The electric crystals are reoriented and combined with the film as described. The electrode is like the gold 13 13 {binding (please read the precautions on the back before filling this page) This paper scale is applicable to the Chinese National Standard (CNS) Λ4 specification (210X297 mm) 38183 ^ 〇〇3 ^ i as B8 C8 D8 VI. Patent application scope 19. The repair method of the liquid crystal display device as described in item 18 of the patent application scope The affiliation is in. The emblem is waiting for the neighboring bridge, and it is in the extreme position iyes, the prime picture is the same as the gold painting. The lack of it makes the point middle road have a very short electric part. The middle pole of the bridge should be electrified, and the other pole should be painted. The decoration part of Huan Huan who was repaired by the rehabilitation person is the short crystal part of Shihji Road, which is given by the liquid bridge, and it is contained in the Rongji Yingrong item. Lei Li used the technical secondary school to apply for the film, which is absolutely impossible (please read the precautions on the back and then fill out this page). Packed.
