Description

[0001] The present invention relates to a mother panel for a liquid crystal display device and a manufacturing method of the liquid crystal display device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mother panel and a liquid crystal display device for a liquid crystal display device, and more particularly to a mother panel for a liquid crystal display device and a method of manufacturing the same.

In general, a liquid crystal display device is a display device that can supply a desired image by controlling a light transmittance of liquid crystal cells by individually supplying data signals according to image information to liquid crystal cells arranged in a matrix form.

Accordingly, a liquid crystal display device is provided with a liquid crystal panel in which liquid crystal cells of a pixel unit are arranged in a matrix form and a driver integrated circuit (IC) for driving liquid crystal cells.

The liquid crystal panel is composed of first and second substrates facing each other and a liquid crystal layer filled between both substrates.

On the first substrate of the liquid crystal panel, a plurality of data lines for transmitting the data signal supplied from the data driver IC to the liquid crystal cell, and a plurality of gates for transferring the gate signal supplied from the gate driver integrated circuit to the liquid crystal cell The wirings are orthogonal to each other, and a liquid crystal cell is defined at each intersection of these data wirings and the gate wirings.

The gate driver integrated circuit sequentially supplies gate signals to a plurality of gate wirings so that liquid crystal cells arranged in a matrix form are sequentially selected one by one, and the liquid crystal cells of the selected one line are supplied with data from the data driver IC A data signal is supplied.

On the other hand, when the driver integrated circuit is mounted on the gate link portion and the data link portion for the gate and the data, respectively, the volume and the weight of the driver integrated circuit are increased. A gate in panel (GIP) incorporating a gate driver is proposed, which is mounted only on one side of the substrate, and the gate driver integrated circuit is formed inside the first substrate of the liquid crystal panel.

In addition, a liquid crystal display device has a structure in which a plurality of first substrates are formed on a large first mother substrate, a plurality of second substrates are formed on a separate second mother substrate, and then two first mother substrates and a second mother substrate By joining them together, a plurality of liquid crystal panels are simultaneously formed to improve the yield.

Accordingly, a step of cutting the mother panel to which the first and second mother substrate plates are attached is cut into a plurality of unit liquid crystal panels.

In general, the cutting of the unit liquid crystal panel is performed by a scribe process of forming a line to be cut on the surfaces of the first and second mother boards with a cutting wheel (not shown) made of a diamond material having a hardness higher than that of glass, And a break process is performed to cut off the impurities.

At this time, a cutting burr may be formed on the cut surfaces of the first and second substrates cut along the line to be cut after the break process.

Since such a cutting burr may damage a cable which is a signal transmission connecting member connecting between circuit boards, the cutting burr must be removed through a separate polishing process.

Conventionally, however, not only a liquid crystal panel in which a cutting burr is formed but also a liquid crystal panel in which a cutting burr is formed must be subjected to a polishing process, which increases the number of manufacturing steps and increases the cost.

Further, since the first and second substrates are generally made of a transparent material and it is difficult to confirm whether a cutting burr is formed on the cut surface by a naked eye or a camera, only a liquid crystal panel in which a cutting burr is formed There is a problem that it is difficult to carry out the polishing process selectively.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and it is an object of the present invention to reduce the number of manufacturing processes by polishing only a unit liquid crystal panel in which a cutting burr is observed by an inspection pattern, (R) and a green (G) color filter formed on the first substrate and the second substrate to uniformly form the thickness of the red (R) and green (G) color filters formed on the substrate.

According to an aspect of the present invention, there is provided a display apparatus including a first mother substrate including a first substrate including an image display unit and a data link unit, a display region facing the first mother substrate and corresponding to the image display unit, A second mother substrate including a second substrate including a dummy region corresponding to a link portion, a black matrix disposed in a display region of the inner surface of the second substrate and partitioning a pixel region, A blue color filter, and a test pattern made of the same material as the blue color filter and arranged in parallel in a dummy area, spaced apart from a line to be cut which divides a display area and a dummy area.

A first mother substrate including a first substrate including an image display unit and a data link unit and a second substrate including a display area corresponding to the image display unit and a dummy area corresponding to the data link unit, Forming a black matrix for partitioning a pixel region in a display region above the second substrate; forming red and green color filters sequentially in the pixel region; Forming a test pattern in a dummy area in parallel with the line to be cut which separates the display area and the dummy area from the same material as the blue color filter and parallel to each other; And cutting the second mother substrate along the line along which the substrate is to be cut.

Since the unit liquid crystal panel in which the cutting burr is observed by the inspection pattern is subjected to the polishing process without having to go through the polishing process for all the unit liquid crystal panels produced by cutting the mother substrate for a liquid crystal display device , The manufacturing cost can be reduced by reducing the number of manufacturing steps.

Further, the thickness of the red (R) and green (G) color filters formed in each pixel region is uniformly formed, and the display quality deterioration can be prevented.

Further, each of the unit liquid crystal panels (100 in Fig. 3F) is appropriately arranged so as to use the first and second mother boards 1001 and 1002 as much as possible. In general, The second dummy area DA2 is formed.

In the display area AA on the inner surface of the second substrate (102 in FIG. 3F), a black matrix 111 for partitioning the pixel area is arranged and red (R), green (G) ) Color filters 113a to 113c are disposed.

The mother panel 1000 for a liquid crystal display according to the first embodiment of the present invention is cut through a scribe process and a break process to produce a plurality of unit panels 100 , The first dummy area DA1 and the second dummy area DA2 are removed.

Specifically, the cutting process of the mother panel 1000 for a liquid crystal display will be described as follows.

First, a scribing process will be described. A first cutting line CL1 for removing the first dummy area DA1 is formed on the first mother substrate 1001 through a cutting wheel (not shown) And a second sectioning line CL2 for removing the second dummy area DA2 is formed on the first and second mother board 1001 and 1002, respectively.

Next, the break process will be described. The first and second mother board 1001 and 1002 are formed with first and second mother board boards 1001 and 1002 along first and second lines of cut lines CL1 and CL2, 1001, and 1002 so as to propagate a crack to the first and second lines along the lines of cut CL1 and CL2.

At this time, a cutting burr is formed on the cut surfaces of the first and second substrates (101 and 102 of FIG. 3F) cut along the first and second lines Ts1 and CL2 after the break process .

In particular, a cutting burr formed on the cut surface of the second substrate (102 of Fig. 3F) cut along the first line along which the substrate is about to be cut CL1 can damage the cable, which is a signal transmission connection member connecting circuit boards have.

Accordingly, in the mother panel 1000 for a liquid crystal display according to the first embodiment of the present invention, the cutting edge of the second substrate (102 in Fig. 3F) cut along the first line along which the object is intended to be cut (CL1) the first dicing area DA1 on the inner surface of the second substrate 102 (see FIG. 3 (f)) is spaced apart from the first intended line of cut CL1 and is inspected in parallel And the pattern 150 is disposed.

At this time, the inspection pattern 150 is made of the same material as the black matrix 111. [

Hereinafter, a method for determining whether or not a cutting burr is formed on the cut surface will be described.

More specifically, in the scribe process, the mother panel 1000 for a liquid crystal display device is subjected to a scribing process having a width CW of 200 to 300 mu m along a first line along which the substrate is to be cut CL1 At this time, a scratch (CW) having a width of 100 to 150 mu m which is half of 200 to 300 mu m is formed in the display area AA and the first dummy area DA1, respectively.

It is also preferable that the inspection pattern 150 is disposed parallel to the first line along which the first object is to be cut CL1 and is spaced apart from the first object to be cut CL1 by half or more of a predetermined distance, for example, a flaw width CW.

It is preferable that the inspection pattern 150 is formed at a predetermined width, for example, at least half the width of the scratch width CW of the first line along which the object is intended to be cut CL1.

This is because if a cutting burr is formed on the cut surface of the second substrate (102 in Fig. 3F) cut along the first line along which the material is to be divided CL1 is cut, This is because the inspection pattern 150 can be easily observed.

First, if a cutting burr is not formed on the cut surface of the second substrate (102 in Fig. 3F) cut along the first line along which the material is to be divided CL1, a scratch formed along the first line along which the material is to be cut The inspection pattern 150 having a constant width is observed when the inspection pattern 150 is observed with the naked eye or the camera because the inspection pattern 150 does not invade or invades the inspection pattern 150 with a constant width.

Next, when a cutting burr is formed on the cut surface of the second substrate (102 in Fig. 3F) cut along the first line along which the material is to be cut (CL1), scratches formed along the first line (1,2) The inspection pattern 150 having an irregular width is observed when observing the inspection pattern 150 formed in the first dummy area DA1 visually or by a camera because it irregularly invites the pattern 150. [

When the inspection pattern 150 having an irregular width is observed, the unit liquid crystal panel 100 of FIG. 3F removes the cutting burr through the polishing process, It is possible to prevent the cable damage due to the cutting burr formed on the cut surface of the second substrate 102 (FIG.

That is, a cutting burr is observed by the inspection pattern 150 without having to undergo a polishing process for all the unit liquid crystal panels (100 in Fig. 3F) generated by cutting the mother substrate 1000 for a liquid crystal display Only the unit liquid crystal panel (100 of FIG. 3F) is subjected to the polishing process, so that the manufacturing cost can be reduced by reducing the number of manufacturing processes.
