The TCPs 110 and 115 are supplied as a long flexible film 114 wound on a reel in a continuous state in a row, and are punched one by one except for defective products found by inspection of the output level. The output level inspection is to inspect whether the difference in signal output level exceeds a permissible value and becomes excessive when a signal of a constant level is input due to variations in internal resistance of the drive IC 112.

The TCPs 110 and 115 are mounted on the liquid crystal cell 150 in the order of punching. And TCP1
T provided on one side of the end along one side of 10,115
The CP output terminal group 111 and the input lead portion of the liquid crystal cell 150 provided in the edge-shaped shelf region 151 of the liquid crystal cell 150 are connected via the anisotropic conductive film 160.

A TCP 110 (X-TCP) having a signal line driving IC mounted on the long side end of the liquid crystal cell 150, and a TCP 115 (X-TCP) having a scanning line driving IC mounted on the short side end.
(Y-TCP) is arranged.

FIG. 9 is an enlarged view of an essential part showing a step of mounting the TCP 110 in the liquid crystal cell 150 and a sectional structure of the TCP 110.

The driving IC 112 is arranged in an opening provided at a substantially central portion of the substrate film 113 of the TCP 110, and is fixed to the substrate film 113 by a filling adhesive 117.

A plurality of output terminals 1 on the lower surface of the drive IC 112
From 18, the output lead wire 116 is connected to the substrate film 113.
A TCP output terminal group 111 is formed which extends to one end edge of the one end and a plurality of output lead wires are exposed on the lower surface of the end portion along the end edge.

The TCP output terminal group 111 is the liquid crystal cell 150.
By being bonded to the edge-shaped shelf region 151 of the liquid crystal cell 150 via the anisotropic conductive film 160, the output lead wire 116 of the TCP output terminal group 111 and the input lead wire 153 of the liquid crystal cell 150 are connected to each other.

In connecting the lead wires 116 and 153, the pitch of the lead wires 116 and 153 is 70 to 100.
Since it is very small, ie, μm, fine alignment is required, and the single-field optical recognition system 170 is used for this purpose.

The one-view optical recognition system 170 includes a liquid crystal cell 15
The relative position of the lead wires 116 and 153 is recognized from below the part where the TCP 110 is attached to 0, and fine alignment is realized. To perform this fine alignment,
TCP output terminal group 111 is all one-view optical recognition system 170
Coarse alignment must be done to a position that fits within the field of view.

In FIG. 10, the TCP 110 has a transfer arm 14.
FIG. 3 is a plan view from above schematically showing a TCP device that carries 0 to the edge-edge shelf-like region 151 of the liquid crystal cell 150.

(1) The TCP 110 is supplied to the TCP transfer stage 180 from the TCP punching unit 182 by the TCP transport unit 181.

(2) Four transport arms 140 are formed in a cross shape and extend horizontally from the vertical rotary shaft 139. An air suction port is provided below the tip of the transfer arm 140, and the TCP transfer stage 1
At 80, the TCP 110 is suction-fixed (vacuum chuck) to the suction port at the tip of the transfer arm 140 (a
position).

(3) Edge-shaped shelf-like region 1 of liquid crystal cell 150
It is conveyed to 51 (position b). It is not necessary to perform the rough alignment described above at this position.
This is because the rough alignment (alignment) is performed when the suction is fixed on the TCP delivery stage 180, and the TCP transfer stage 180 is fixed so as not to be misaligned during the transportation by the transport arm 140 that rotates.

In such a conventional technique, when a small piece of conductive foreign matter (hereinafter referred to as dust) such as a minute metal piece adheres to the TCP output terminal group 111, the pitch is 70 in recent years.
TCP for signal line drive, which has become extremely narrow to 100 μm
The output lead wires 116 of 110 are short-circuited with each other, which is an important cause of defective products.

On the other hand, the X-TC mounted on the liquid crystal cell 50
Even if the output level of P110 is within the inspection pass range, two X-TCP110 close to the upper limit and the lower limit of this range may be arranged adjacent to each other. In this case, two XTs
Since the output level of the CP 110 is large, there is a display defect (uneven division) in which a boundary between the pixel regions is recognized due to a difference in luminance or saturation between adjacent pixel regions controlled by these.

[0019]

According to the conventional method of manufacturing a display device, when a conductive small piece is attached between the TCP output terminal group and the input portion of the liquid crystal cell,
The TCP output lead wires with a narrow pitch caused short-circuiting with each other, resulting in display failure.

The present invention provides a method for manufacturing a display device which prevents such product defects most simply and surely and does not impair other production efficiency at all.

The present invention also provides a method of manufacturing a display device capable of preventing the occurrence of divisional unevenness.

The TCP supply unit 82 that supplies the data will be described later.

As shown in FIG. 2, the TCP 10 is formed by mounting a drive IC 12 for driving a display device on a central portion of a substantially rectangular substrate film 13.
On the lower surface of 3, a plurality of output leads 16 are juxtaposed from the central drive IC 12 toward one long side, and a TCP output terminal group 11 is provided at the tip thereof. Also, drive I
The input leads 19 are arranged in parallel from C12 toward the other long side, and an input terminal group 45 is provided near the tip thereof.

As shown in FIG. 1, four transport arms 40 extend horizontally from a vertical rotary shaft 39 in a cross shape. One transfer arm 40 with the TCP 10 suction-fixed at the TCP transfer stage 80 (position A)
Is 27 clockwise when viewed around the rotary shaft 39 from above.
The TCP 10 is rotated by 0 ° and is transported to the mounting position (D position) of the edge-edge shelf-like region 51 of the liquid crystal cell 50. Then, the TCP 10 attached to one transfer arm 40
Is finely adjusted at the TCP mounting location (D position) of the edge portion 51 of the liquid crystal cell 50, and is temporarily pressure-bonded. During this time, the tips of the other three transfer arms 40 are located at the TCP transfer stage 80 (position A), at a position rotated by 90 ° (position B) and at a position rotated by 180 ° (position C).

As shown in FIG. 3, the transfer arm 40 is provided with a suction port 41 at the lower end of the transfer arm 40 and is vacuum-sucked from a pressure-reducing line connecting joint 43. In the TCP transfer stage 80, TC is attached to the suction port 41 of the transfer arm 40.
P10 is fixed by suction from above. At this time, the end portion of the TCP 10 provided with the TCP output terminal group 11 slightly protrudes outward from the end edge of the tip of the transfer arm 40.
In addition, an elastic body 42 is provided at the edge of the suction port 41, that is, at the contact portion with the TCP 10.

The rotary brush unit 20 and the dust suction units 30 and 31 are provided at the C position immediately before the mounting position (D position) of the TCP 10 to the liquid crystal cell 50.

Rotary brush 21 of rotary brush unit 20
Has a horizontal rotation axis and is provided immediately below the TCP output terminal group 11 at the C position, and the brush surface is TC.
It has a size sufficient to contact the entire P output terminal group 11 at one time. The rotating belt 2 is attached to the rotating brush 21.
Rotational motion of the bearing 23 is transmitted via 2, and vertical motion of the bearing 23 by the cam 24 is also transmitted.

Adjacent to the brush surface of the rotary brush 21, dust suction ports 32, 33 having a substantially rectangular shape are arranged above and below the rotary brush 21. The horizontal length is the rotating brush 21.

The dust suction ports 32 and 33 are connected to the decompression line via decompression line connection joints 34 and 35 and a dust removal filter, respectively.

The operating state of the TCP transport device 1 will be described below.

(1) The TCP 10 is sucked and fixed to the suction port 41 at the tip of the transfer arm 40 (position A).

(2) The tip of the transfer arm 40 moves to the C position.

(3) In synchronism with the above movement of the transfer arm 40, the rotary brush 21 is lifted upward by the cam 24 and brought into contact with the TCP output terminal group 11 in a rotating state. In this case, the entire surface of the TCP output terminal group 11 is abutted so as to cover it from directly below. Therefore, the rotating brush 21 is brushed over the entire surface of the TCP output terminal group 11 without moving the rotating brush 21 in the horizontal direction.

In the above, the transfer arm C is moving.
Although the dust is removed at the position, the transfer arm may be completely stopped at the C position.

A TC is attached to the suction port 41 of the transfer arm 40.
Since P10 is firmly suctioned and fixed and the external force transmitted to TCP10 by brushing or dust suction is sufficiently small, TCP10 is displaced with respect to transfer arm 40 during brushing. There is no such thing.

With the TCP transport device as described above, the pitch of the output lead wires 16 of the TCP 10 on the signal line driving side is 70.
Despite being as small as μm, the manufacturing yield rate in the TCP 10 mounting step reached 99%. The yield rate in the TCP mounting step is 9 when the manufacturing is performed in the same manner by the conventional technique without using such a dust removing device.
It is about 0%.

Further, with the TCP transport device as described above,
It does not impair the productivity of the prior art.

The liquid crystal cell dust detection device 2 includes a CCD camera 70, a display device 71, and a halogen lamp 72.
The input terminal portion 53 provided in the edge-shaped shelf 51 of the liquid crystal cell 50 is enlarged and displayed on the display screen 71a. This makes it possible to easily detect whether or not the dust 73 is attached.

The CCD camera 70 sequentially captures partial images of the surface of the input terminal group 53 as the liquid crystal cell 50 is sequentially moved on the liquid crystal cell transport stage 55 in the TCP mounting process. The directional halogen lamp 72 illuminates the field of view of the CCD camera 70. The display device 71 includes an image binarization processing device, and a CCD
The image obtained by the camera 70 is converted into an image divided into a black portion and a white portion and displayed on the display screen 71a. Thus, the dust 73 can be easily identified on the display screen 71a.

When dust is detected by the liquid crystal cell dust inspecting device 2, the dust-adhered portion is blown with air to remove the dust. At this time, a suction port of the vacuum device is also provided in the vicinity.

As described above, by performing the dust inspection and the dust removal on the liquid crystal cell input terminal group 53, the product yield rate can be further improved as compared with the case where the dust removal is performed only on the TCP output terminal group 11.

Next, the TCP supply unit 82 in this embodiment will be described with reference to FIGS. 5, 6 and 2.

As shown in the conceptual diagram of FIG. 5, the TCP supply unit 82 includes the long flexible film 14 to the TC.

9 is for measuring the power level of the output from the corresponding output terminal when a constant input signal is input from the TCP input terminal. In this embodiment, TCP1
The output level related to the internal resistance of the drive IC 12 is measured only for the wirings on both ends of 0. That is, the output level between the input terminal 11a at one end and the output terminal 45a at the corresponding end and between the input terminal 11b at the other end and the output terminal 45b at the corresponding end shown in FIG. The inspection is done.

Using the schematic diagram of FIG. 6, TC on the signal input side
TCP supply unit 8 when mounting P (X-TCP)
Operation 2 will be described.

Although omitted in the following description, as in the prior art, when the output level of TCP is poor, that is,
If it is outside the non-defective range L, it is excluded by the TCP classification device 86.

(1) TC which is first punched from the long flexible film 14 by the TCP punching device 85.
P10- # 1 is sent to the TCP transfer stage 80 after the output level is measured by the TCP output inspection device 83. After that, by the above-described carrying process described with reference to FIGS. 1 to 3, the X-TCP 10-1 at the first position counted from the end on the Y-TCP 15 side is attached to the shelf-shaped edge portion 51.

(2) The TCP 10- # 2 secondly punched by the TCP punching device 85 has its output level with the X-TCP 10-1 at the first position measured by the TCP output inspection device 83. The difference is the set allowable limit M
Is determined to be within the range. Based on the pass / fail result of this determination, the TCP sorting device 86 sends the X-TCP at the second position from the end to the TCP transfer stage 80 if the result is acceptable.
It is sent as 10-2, and if it fails, it is sent to the TCP temporary storage shelf 84.

(3) The second punched TCP 10-
When # 2 is determined to be acceptable in (2) above and is mounted as the X-TCP10-2 at the second position, then the pass / fail determination is made for the third punched X-TCP10- # 3. . If it passes, X at the 3rd position
As TCP10-3, it is attached to the liquid crystal cell 50 through the TCP transfer stage 80, and if it is not passed, it is sent to the TCP temporary storage shelf 84.

The pass / fail judgment is made on the second X-TCP 10-2.
And the output level difference with is within the set allowable limit M,
In addition, it is performed depending on whether the output level difference from the first X-TCP 10-1 is within the set allowable limit N. Here, M ≦ N <L.

(4) Second punched TCP 10-
When # 2 is rejected in the above (2), the same process as the above (2) is immediately performed on the third punched TCP 10- # 3.

(5) The X-TCP 10 mounted at the second to eighth positions from the end by the steps (2) to (4) above.
-2, ..., 10-8 are sequentially selected. However, TCP
When the X-TCP 10 is stored in the temporary storage rack 84, the TCP 10 stored therein is prioritized over the punched TCP 10 and the pass / fail judgment is performed. It is pulled out from the TCP temporary storage shelf 84 and used for mounting on the liquid crystal cell 50.

As described above, the X-TCP at the nth position
X at the (n + 1) th position arranged adjacent to 10-n
As -TCP10- (n + 1), the one whose output level difference is within the set allowable limit is selected. Therefore, the pixel area to which the image signal is input by the X-TCP10-n at the n-th position and the (n + 1) -th pixel area are selected. X-TCP10- (n +
The difference in brightness and saturation of the image from that in 1) is not visually recognized.

As a series of X-TCPs 10-1 to 10-8 mounted on one liquid crystal cell 50, those having a difference in output level from the first mounted X-TCP 10-1 within a set value are set. Since the selection is made, the difference in brightness and saturation between both end regions in the display region of one liquid crystal cell 50 is not visually recognized.

Therefore, the above TCP supply unit 8
By supplying the TCP 10 according to No. 2, uneven display and uneven display due to variations in the output level of the TCP are completely prevented.

In the above-mentioned operation of the TCP supply unit 82, only the judgment is made as to whether or not the difference in the output level from the X-TCP 10-1 at the first position is within the set allowable limit M. Even if the sorting is performed, if the value of the set allowable limit M at this time is sufficiently small, it is possible to sufficiently prevent uneven division.

In the operation of the TCP supply unit 82 described above, instead of measuring the output level and sorting based on the output level in the punched order, the output levels of a large number of TCPs 10 are measured in advance, and based on this, It is also possible to collectively determine the selection and arrangement of the eight X-TCPs mounted on one liquid crystal cell 50.

Next, an embodiment using the TCP dust detection device 3 for inspecting dust on the output terminal group 11 of the TCP 10 will be described with reference to FIG.

The TCP dust detection device 3 comprises a CCD camera 70, a display device 71, and a halogen lamp 72, which are exactly the same as the liquid crystal cell dust inspection device 2.
A greatly enlarged image of the output terminal group 11 of the TCP 10 is displayed on the display screen 71a. This gives T
It is possible to easily detect whether or not the dust 73 is attached to the output terminal group 11 of the CP 10.

The TCP dust detection device 3 is provided in the middle of the positions (C) and (D) in FIG.
Check if the debris removal at the location is complete. If dust remains, the transfer arm is rotated in the reverse direction and the dust removal at position (C) is repeated again.

As described above, by confirming the dust removal of the TCP output terminal group 11 by the dust inspection device and repeating the dust removal operation based on this result, the product yield rate can be further improved.
