The present invention relates to a repair apparatus and a repair method of a liquid crystal display device, and in particular, a repair apparatus of a liquid crystal display device capable of improving a yield of a liquid crystal display device by removing defective pixels caused by foreign substances mixed between the thin film and the thin film and the same. It is related with the repair method used.

A liquid crystal display displays an image by adjusting the light transmittance of a liquid crystal using an electric field. Such liquid crystal displays are classified into vertical electric field types and horizontal electric field types according to the direction of the electric field for driving the liquid crystal.

In the vertical field type liquid crystal display, the common electrode formed on the upper substrate and the pixel electrode formed on the lower substrate are disposed to face each other to drive the liquid crystal of TN (Twisted Nematic) mode by a vertical electric field formed therebetween. Such a vertical field type liquid crystal display device has an advantage of large aperture ratio but a narrow viewing angle.

In the horizontal field type liquid crystal display, a liquid crystal in an in-plane switching mode is driven by a horizontal electric field between a pixel electrode and a common electrode disposed side by side on a lower substrate. The horizontal field type liquid crystal display device has a wide viewing angle, but has a narrow aperture ratio.

Hereinafter, a horizontal field type liquid crystal display device will be described in detail with reference to FIGS. 1 and 2.

1 and 2, a horizontal field type liquid crystal display device includes a thin film transistor array substrate 50 and a color filter array substrate 60 bonded together to face each other, and a liquid crystal space provided between the two substrates 50 and 60. The liquid crystal 40 filled in is provided.

The color filter array substrate 60 may include a black matrix 32, a color filter 34, a black matrix 32, and a color filter 34 formed on the upper substrate 11. The planarization layer 36 which planarizes, the pattern spacer 13, and the upper alignment film 38 apply | coated for the orientation of the liquid crystal 40 on them are provided.

The thin film transistor array substrate 50 includes a gate line 2 and a data line 4 intersected on the lower substrate 1, a thin film transistor 30 formed at each intersection of the two and four gates, and a gate line. A pixel electrode 22 and a common electrode 24 formed in a pixel region provided in a cross structure of (2) and the data line 4 to form a horizontal electric field, and a common line 26 connected to the common electrode 24. And a lower alignment film 28 coated thereon for alignment of the liquid crystals 40.

In the color filter array substrate 60, the black matrix 32 serves to provide a pixel area where the color filter 34 is to be formed, and to prevent light leakage and to absorb external light to increase contrast. The color filter 34 is formed over the pixel region separated by the black matrix 32 and the black matrix 32, and is formed for each of R, G, and B to implement R, G, and B colors. The pattern spacer 13 maintains a gap between the color filter array substrate 60 and the thin film transistor array substrate 50 so that the liquid crystal 40 is between the thin film transistor array substrate 50 and the color filter array substrate 60. ) To provide a liquid crystal space.

In the thin film transistor array substrate 50, the gate line 2 supplies a scan signal to the gate electrode 9 of the thin film transistor 30. The data line 4 supplies the pixel signal to the pixel electrode 22 through the drain electrode 42 of the thin film transistor 30. The common line 26 is formed in parallel with the gate line 2 with the pixel region therebetween to supply a reference voltage for driving the liquid crystal 40 to the common electrode 24. The thin film transistor 30 includes a gate electrode 9 formed with the gate line 2, source and drain electrodes 41 and 42 formed with the data line 4, a gate electrode 9 and a gate insulating film. An active layer 14 which overlaps with the interposed 44 and forms a channel between the source electrode 41 and the drain electrode 42, and the contact between the active layer 14 and the source and drain electrodes 41 and 42; Ohmic contact layer 47 for reducing the resistance is included. The pixel electrode 22 is connected to the drain electrode 42 exposed through the pixel contact hole 48 penetrating the passivation layer 46. The thin film transistor 30 keeps the pixel signal from the data line 4 charged and held in the pixel electrode 22 in response to the scan signal from the gate line 2. A horizontal electric field is formed between the pixel electrode 22 supplied with the pixel signal through the thin film transistor 30 and the common electrode 24 supplied with the reference voltage through the common line 26. The liquid crystal 40 is rotated by dielectric anisotropy between the thin film transistor array substrate 50 and the color filter array substrate 60 by this horizontal electric field. The liquid crystal display device implements an image by varying the light transmittance of the pixel region according to the degree of rotation of the liquid crystal 40.

On the other hand, in the process of manufacturing the liquid crystal display device in the liquid crystal display device, for example, between the thin film and the thin film when moving to a separate chamber or a third place for forming another thin film As shown in FIG. 3, the foreign material 55 is often settled between the color filter 34 and the planarization layer 36. At this time, the upper alignment layer 38 corresponding to the foreign material 55 is not rubbed uniformly during the rubbing process for forming the foreign material 55, so that the non-uniform alignment region A is formed in the liquid crystal display device. Occurs.

The non-uniform alignment region A causes light leakage in the liquid crystal display by disturbing the light transmittance of the liquid crystal, and bright spots due to light leakage are generated in the liquid crystal display when the LCD is black driven.

In general, when a high gray is implemented, a dark spot is seen by a light fountain as a dark spot, and when a low gray is implemented, a bright spot is shown by a light fountain as a bright point. The human eye responds more sensitively to bright spots than to dark spots. Therefore, the failure determination of the liquid crystal display device imposes a stricter criterion on the failure of the bright point than the dark point. Accordingly, the liquid crystal display device minimizes the defective rate by darkening the bright point in order to minimize the defective rate.

Hereinafter, a method of repairing a liquid crystal display device by darkening the bright point caused by the non-uniform alignment region A will be described with reference to FIGS. 4A to 4C.

Then, the plurality of thin films 34, 36, and 38 in the region where the foreign material 55 and the foreign material 55 are mixed are removed as shown in FIG. 4B by the irradiated laser. Then, the repair of the liquid crystal display device uses the ink jet 75 in the region where the plurality of thin films 34, 36, and 38 together with the foreign material 55 are removed, as shown in FIG. 4C. Filling 76) darkens the region from which the plurality of thin films 34, 36, 38 along with the foreign material 55 have been removed. As a result, in the liquid crystal display device, the area where the foreign material 55 is mixed is darkened and the quality is judged to improve the yield.

However, in the conventional liquid crystal display, when the number of dark spots generated during the process and the dark spots darkened by the repair exceeds a total of five (the number may vary depending on the model), it is determined to be defective. have. That is, the repair of the conventional liquid crystal display has a disadvantage that its application is limited by the number of dark spots generated during the process and the dark spots darkened by the repair.

In addition, the repair of the conventional liquid crystal display device has a problem such that clogging occurs in the nozzle exposing the black material 76 and an expensive ink jet for filling the black material 76 ( 75), and a separate line for repairing the liquid crystal display using the ink jet 75 has to be prepared separately, thereby increasing the manufacturing cost.
