However, the thin film transistor array substrates 111 or the color filter substrates 121 fabricated on the first mother substrate 110 and the second mother substrate 120 have defects due to unexpected defects in the respective manufacturing processes. May occur. Thus, the case where a defect occurred was shown as "NG (no good)" on the figure, and the case where a defect did not occur was shown as "G (good)" on the figure.

Accordingly, when the first mother substrate 110 and the second mother substrate 120 are bonded to each other and then cut into individual unit liquid crystal display panels, the thin film transistor array substrate 111 and the color filter substrate 121 marked with “G” may be used. The thin film transistor array substrate 111 marked with "NG" and the color filter substrate 121 marked with "G" may be bonded together and cut into the unit liquid crystal display panel or may be cut into the unit liquid crystal display panel.

As described above, the thin film transistor array substrate 111 labeled "NG" and the color filter substrate 121 labeled "G" are bonded to each other and cut into a unit liquid crystal display panel, or the thin film transistor array substrate 111 labeled "G" and " When the color filter substrate 121 marked NG "is bonded and cut into the unit liquid crystal display panel, the unit liquid crystal display panel cannot be commercialized and must be disposed of.

Accordingly, the thin film transistor array substrate 111 marked "NG" and the color filter substrate 121 marked "G" are bonded or the thin film transistor array substrate 111 marked "G" and the color filter substrate 121 marked "NG". A classifier is used to prevent this from adhering and to minimize the number of liquid crystal display panels disposed of.

6 is an exemplary view illustrating a classifier of a conventional liquid crystal display panel.

Referring to FIG. 6, the classifier of the liquid crystal display panel may include a frum-port (from port FP1) to which a first mother substrate is transferred and a defect of the thin film transistor array substrates fabricated on the first mother substrate. A first mother substrate sorting unit 210 having sorting ports A1 to G1, S1, and T1 in which the first mother substrate is sorted and transferred from the FP1; A first mother substrate transfer robot (211) for transferring the first mother substrate from the frum-port (FP1) to the sorting ports (A1 to G1, S1, and T1); The sorting ports A2 through which the second mother substrate is classified and transferred from the frum-port FP2 according to whether the frum-port FP2 to which the second mother substrate is transferred and the color filter substrates manufactured on the second mother substrate are defective. A second mother substrate sorter 220 having G2, S2, and T2; A second mother substrate transfer robot 221 transfers the second mother substrate from the frum-port FP2 to the sorting ports A2 to G2, S2, and T2.

The first and second mother substrate classifiers classified according to the defective states of the color filter substrates are classified according to the defective states of the thin film transistor array substrates in the first mother substrate classifier 210. The two mother substrates are transferred to the bonding part 230 and are bonded to each other, and the bonded first mother substrate and the second mother substrate are cut into the unit liquid crystal display panel at the cutting part 240.

Conventionally, six thin film transistor array substrates are fabricated on the first mother substrate, six color filter substrates are fabricated on the second mother substrate, and classification according to a defective state is performed by a classifier of the liquid crystal display panel.

That is, the first mother substrate transfer robot 211 receives information regarding a defective state of the thin film transistor array substrates fabricated on the first mother substrate from a host computer (not shown in the drawing), and thus the six mother substrate transfer robots 211 are defective. In the absence of the first mother substrate is transferred from the frum-port (FP1) to the G-type sorting port (G1), the second mother substrate transfer robot 221 is similarly produced on the second mother substrate from the host computer The second mother substrate is transferred from the frum-port FP2 to the G-type sorting port G2 when there are no defects of the six color filter substrates by receiving information according to the defective state of the color filter substrates.

The first mother substrate and the second mother substrate transferred to the G-type sorting ports G1 and G2 are transferred to the bonding portion 230 and are bonded to each other, and the bonded first mother substrate and the second mother substrate are cut portions ( In operation 240, the unit liquid crystal display panel is cut to prevent unit defects from occurring in all unit liquid crystal display panels.

In addition, when the first mother substrate transfer robot 211 receives information from the host computer according to the defective state of the thin film transistor array substrates manufactured on the first mother substrate, when one of the six thin film transistor array substrates is defective. According to the position of the defective thin film transistor array substrate, the first mother substrate is moved from the frum-port FP1 to the A-type sorting port A1, the B-type sorting port B1, and the C-type sorting port C1. And classify and transfer to the D-type sorting port (D1), the E-type sorting port (E1) and the F-type sorting port (F1). Similarly, the second mother substrate transfer robot 221 is a second computer from the host computer. If one of the six color filter substrates is defective by receiving information according to the defective state of the color filter substrates manufactured on the mother substrate, the second mother substrate is connected to the frum-port according to the position of the color filter substrate where the defects are generated. A-type sorting port (A2) from FP2 ), B-type sorting port (B2), C-type sorting port (C2), D-type sorting port (D2), E-type sorting port (E2) and F-type sorting port (F2) do.

The A-type sorting port (A1, A2), B-type sorting port (B1, B2), C-type sorting port (C1, C2), D-type sorting port (D1, D2), E-type sorting port The first mother substrate and the second mother substrate transferred to the (E1, E2) and the F-type sorting ports (F1, F2) are respectively transferred to the bonding portion 230 so that a defect occurs in the thin film transistor array substrate and the color filter substrate. The first mother substrate and the second mother substrate are bonded to each other so that the bonded first mother substrate and the second mother substrate are cut into the unit liquid crystal display panel at the cutting unit 240, so that a defect occurs in only one unit liquid crystal display panel.

In addition, the first mother substrate transfer robot 211 receives information from the host computer according to the defective state of the thin film transistor array substrates fabricated on the first mother substrate, and the defects of two or more of five thin film transistor array substrates are defective. If present, the first mother substrate is transferred from the frum-port FP1 to the T-type sorting port T1. Similarly, the second mother substrate transfer robot 221 is a color manufactured on the second mother substrate from the host computer. The second mother substrate is transferred from the frum-port FP2 to the T-type sorting port T2 when two or more of the six color filter substrates have defects according to the information on the defective states of the filter substrates. .

The first mother substrate and the second mother substrate transferred to the T-type sorting ports T1 and T2 are transferred to the bonding part 230 and are bonded to each other, and the bonded first mother substrate and the second mother substrate are cut portions ( In 240, a unit liquid crystal display panel is cut. In this case, two or more thin film transistor array substrates and color filter substrates manufactured on the first mother substrate and the second mother substrate have defects of two or more and five or less, respectively. At least two liquid crystal display panels may cause defects in all unit liquid crystal display panels. Therefore, the first mother substrate and the second mother substrate transferred to the T-type sorting ports T1 and T2 are classified according to the defective positions of the thin film transistor array substrate and the color filter substrate by separate sorters. The generated thin film transistor array substrate and the color filter substrate may be bonded to each other.

The first mother substrate transfer robot 211 receives information according to a defective state of the thin film transistor array substrates fabricated on the first mother substrate from a host computer and, when all six thin film transistor array substrates are defective, The first mother substrate is transferred from the frum-port FP1 to the S-type sorting port S1 and disposed of through the disposal unit 212. Similarly, the second mother substrate transfer robot 221 is configured to transfer a second mosquito from the host computer. When all six color filter substrates are defective by receiving information on the defective state of the color filter substrates manufactured on the plate, the second mother substrate is transferred from the frum-port FP2 to the S-type sorting port S2. To be discarded through the disposal unit 222.

However, the sorter of the conventional liquid crystal display panel as described above has a problem in that the number of the thin film transistor array substrate and the color filter substrate fabricated on the first mother substrate and the second mother substrate increases.

In other words, by increasing the number of thin film transistor array substrates and color filter substrates simultaneously on a large area mother substrate, the yield of the liquid crystal display panel has been improved. Alternatively, a larger number of thin film transistor array substrates or color filter substrates are being manufactured at the same time.

For example, when nine thin film transistor array substrates and color filter substrates are fabricated on the first mother substrate and the second mother substrate, and defects occur randomly on the nine thin film transistor array substrates and the color filter substrates. It is not possible to respond appropriately and secondary classification should be carried out through a separate classifier.

As described above, the classifier of the conventional liquid crystal display panel requires a separate classifier when the number of unit liquid crystal display panels fabricated in a large area mother substrate increases, thereby occupying a certain space in a clean room. As a result, there is a problem in that the equipment cost is increased, and also the work path of the transfer robot for classifying the liquid crystal display panel is increased, resulting in a decrease in productivity.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to fabricate a plurality of thin film transistor array substrates or color filter substrates on a large area mother substrate. A sorter of a liquid crystal display panel which may correspond to the number of array substrates or color filter substrates, and classifies the thin film transistor array substrates and the color filter substrates in which a defect occurs to correspond to each other, thereby improving the yield of the liquid crystal display panel.
