Description
본 발명은 액정표시장치의 제조방법에 관한 것으로서, 보다 상세하게는 액정표시장치의 팬아우트라인(데이타패드측 또는 게이트패드측)에 발생하는 단선 또는 단락을 수리할 수 있는 리페어라인이 형성된 액정표시장치 및 그 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a liquid crystal display device, and more particularly, to a liquid crystal display device having a repair line capable of repairing disconnection or short circuit occurring in a fan outline (data pad side or gate pad side) of the liquid crystal display device. And to a method for producing the same.
종래기술에 따른 액정표시장치의 팬아우트부에서의 단선에 대해 도 1 내지 도 3을 참조하여 설명하면 다음과 같다.The disconnection in the fan out part of the liquid crystal display according to the related art will be described with reference to FIGS. 1 to 3 as follows.
도 1은 일반적인 액정표시장치에 있어서, 데이타 또는 게이트라인의 팬아우트부와 연결된 데이터 아우터리드 본딩패드(OLB; outer lead boding pad, 또는 게이트 아우터리드 본딩패드)가 도시된 레이아웃도이다.FIG. 1 is a layout diagram illustrating a data outer bond pad (OLB) connected to a fan out portion of a data or gate line in a general liquid crystal display.
도 2은 종래기술에 따른 액정표시장치의 팬아우트부에서의 단선을 설명하기 위한 도면으로서, 도 1의 "A"부를 확대한 도면이다.FIG. 2 is a view for explaining disconnection in a fan out part of a liquid crystal display according to the related art, and is an enlarged view of part “A” of FIG. 1.
도 3는 종래기술에 따른 액정표시장치의 팬아우트부에 있어서, 팬아우트부가 단선된 경우를 나타낸 도면이다.FIG. 3 is a diagram illustrating a case where the fan outlet part is disconnected in the fan outlet part of the liquid crystal display according to the related art.
종래기술에 따른 액정표시장치의 팬아우트부는, 도 1의 "A"를 확대도시한 도 2에 도시된 바와같이, 어레이기판(미도시)의 데이터OLB패드(outer lead bonding pad)(1)에 데이타라인(3)과 연결되는 다수의 팬아우트라인(3a)이 형성되어 있고, 활성영역(7)상에는 게이트 OLB패드(미도시)쪽에 연결되는 다수의 팬아우트라인(5a)에 연장된 게이트라인(5)이 데이타라인(3)과 수직 교차되게 형성되어 있다. 여기서, 미설명부호 A는 액정표시소자의 유리가장자리부이고, B는 스크라이브라인(활성영역의 가장자리부)이며, C는 트랜지스터의 가장자리부이다.As shown in FIG. 2, which enlarges "A" of FIG. 1, the fan out portion of the liquid crystal display according to the related art is connected to an data lead lead bonding pad 1 of an array substrate (not shown). A plurality of fan outlines 3a are formed to be connected to the data lines 3, and the gate lines 5 extending to the plurality of fan outlines 5a connected to the gate OLB pads (not shown) are formed on the active region 7. ) Is perpendicular to the data line (3). Here, reference numeral A denotes the glass edge of the liquid crystal display element, B denotes the scribe brine (the edge of the active region), and C denotes the edge of the transistor.
그러나, 상기 종래기술에 의하면, 화소의 결함이 발생하는 원인은 여러가지가 있는데, 도 3에 도시된 바와같이, 데이터라인이나 게이트라인에서의 팬아우트라인(3a)에서의 단선(9) 또는 단락은 화소결함이나 선 결함을 일으키게 되므로 문제가 된다.However, according to the prior art, there are various causes of pixel defects. As shown in Fig. 3, the disconnection 9 or short circuit in the fan line 3a in the data line or the gate line indicates a pixel. This is a problem because it causes defects or line defects.
이러한 불량을 줄이기 위한 방법으로는 리페어라인을 설치하여 불량이 발생할때 리페어라인을 이용하여 단선을 구제하는 방법 또는 끊어진 부분을 직접 금속배선을 부분 형성하여 연결하는 방법 등이 제시되어 화소부의 라인단선이나 단락에 의한 결함을 해결하였었다.In order to reduce such defects, a repair line may be installed to repair a disconnection using a repair line or a method of connecting a broken part directly by forming a metal wiring part. The short circuit defect was solved.
그러나, OLB패드(out lead bonding pad)로부터 화소에 신호를 인가해 주는 팬아우트부에서 발생하는 불량은 리페어되지 않게 된다. However, defects occurring in the fan out part that applies a signal to the pixel from an out lead bonding pad (OLB pad) are not repaired.
이러한 불량은 주로 공정진행상의 부주의에 의한 스크래치(scratch)나 ESD성 결함이 주류를 이룬다. 특히, 박막트랜지스터 액정표시장치의 시장이 고해상도의 패널을 요구함에 따라 화소사이즈의 감소와 함께 팬아우트부의 폭과 간격이 감소하게 되므로 라인의 단선과 단락에 의한 불량률은 더욱 증가하게 된다.These defects are mainly made up of inadvertent scratches or ESD defects. In particular, as the market for thin film transistor liquid crystal display devices demands high-resolution panels, the width and spacing of the fan outlet portion decreases as the pixel size decreases, thereby increasing the defective rate due to line breaks and short circuits.
한편, 도 3에서와 같이, 팬아우트라인(9)이 단락 또는 단선되면 주사선과 신호선의 신호가 왜곡되거나 화소에 제대로 인가되지 않아 정상적인 구동을 하지 못하게 되어 선결함을 일으키게 된다.On the other hand, as shown in FIG. 3, when the pan-out line 9 is shorted or disconnected, signals of the scan line and the signal line are distorted or not properly applied to the pixels, thereby preventing normal driving and causing predecessor.
이러한 경우의 액정표시소자는 대부분 패일(fail)처리되기 때문에 팬아우트부가 단선되는 경우를 대비하여 이를 리페어할 수 있는 방법이 필요하다.In this case, since most of the liquid crystal display devices are failed, a method of repairing the liquid crystal display is required in case the fan out part is disconnected.
이에 본 발명은 상기 종래기술의 제반 문제점을 해결하기 위하여 안출한 것으로서, 리페어라인을 단선된 팬아우트라인에 연결하여 단선을 수리해 주므로써 수율을 향상시킬 수 있는 리페어라인이 형성된 액정표시장치 및 그 제조방법을 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned problems of the prior art, a liquid crystal display device having a repair line formed therein to improve the yield by repairing the disconnection by connecting the repair line to the disconnected fan out line and its manufacture The purpose is to provide a method.

본 발명에서는 데이터라인의 팬아우트라인에서의 단선 및 단락 수리방법에 대해서만 설명하였으나, 게이트라인의 팬아우트라인에서의 단선 및 단락 수리방법도 데이터라인에서와 동일하기 때문에 이에 설명을 생략하기로 한다.In the present invention, only the disconnection and short-circuit repair methods of the data line in the fan out line have been described. However, since the disconnection and short-circuit repair methods in the fan out line of the gate line are the same as in the data line, the description thereof will be omitted.
본 발명의 제1실시예에 따른 리페어라인이 형성된 액정표시장치 및 그 제조방법은, 먼저 도 4에 도시된 바와같이, 어레이기판(미도시)의 데이타OLB패드(out lead bonding pad)(11)에 활성영역(17)에서의 데이타라인(13)과 연결되는 다수의 팬아우트라인(13a)이 형성되어 있고, 활성영역(17)상에는 게이트 OLB패드(미도시)에 연결되는 다수의 게이트팬아우트라인(미도시)이 연결되는 게이트라인(15)이 상기 팬아우트라인(13a)과 연결되는 데이터라인(13)과 수직 교차되게 형성되어 있다. 여기서, 미설명부호 B는 스크라이브라인(활성영역의 가장자리부)이고, C는 박막트랜지스터 가장자리부이다. 또한, 상기 팬아우트라인은 데이타패드측으로 국한되지 않고 게이트패드측에도 동일하게 적용할 수 있다.According to the first embodiment of the present invention, a liquid crystal display device having a repair line and a method of manufacturing the same are as shown in FIG. 4. The data OLB pad (out lead bonding pad) 11 of the array substrate (not shown) is first shown in FIG. 4. A plurality of fan outlines 13a are formed in the active region 17 and connected to the data lines 13, and a plurality of gate pan outlines connected to the gate OLB pads (not shown) are formed on the active region 17. A gate line 15 connected to the fan line 13a is vertically intersected with the data line 13 connected to the fan out line 13a. Here, reference numeral B denotes a scribe brine (edge of the active region), and C denotes a thin film transistor edge. In addition, the fan out line is not limited to the data pad side but can be similarly applied to the gate pad side.
또한, 상기 데이타라인(13)과 연결되는 다수의 팬아우트라인(13a)중에는 단선된 팬아우트라인(19)이 포함되어 있다.In addition, among the plurality of fan outlines 13a connected to the data line 13, a disconnected fan out line 19 is included.
그리고, 상기 단선된 팬아우트라인(19)의 양측에 상기 팬아우트라인과는 다른 금속으로 된 리페어라인(21)이 연결되어 있다. 이때, 상기 단선된 팬아우트라인 (19)의 양측은 상기 리페어라인(21)과 만나는 웰딩부(23)에서 웰딩하여 연결한다. 또한, 상기 리페어라인(19)은, 상기 팬아우트라인(13a)이 게이트금속으로 구성되어 있으면 소오스/드레인 금속으로 형성하며, 소오스/드레인금속으로 구성되어 있으면 게이트금속으로 형성한다.A repair line 21 made of a metal different from the fan out line is connected to both sides of the disconnected fan out line 19. At this time, both sides of the disconnected pan out line 19 are welded and connected in the welding part 23 which meets the repair line 21. The repair line 19 is formed of a source / drain metal when the fan out line 13a is made of a gate metal, and is formed of a gate metal when it is made of a source / drain metal.
상기 구성에서와 같이, 상기 단선된 팬아우트라인(19)의 양측에 상기 팬아우트라인과는 다른 금속으로 된 리페어라인(21)이 연결되어 있어, 팬아우트라인에 단선이 발생하더라도 단선된 라인과 리페어라인을 쇼트(short)시켜 단선에 의한 선 결함을 방지할 수가 있다.As in the above configuration, a repair line 21 made of a metal different from the fan out line is connected to both sides of the disconnected fan out line 19, so that even if a disconnection occurs in the fan out line, the disconnected line and the repair line are removed. By shorting it, the line defect by disconnection can be prevented.
한편, 본 발명의 제2실시예에 의하면, 도 5에 도시된 바와같이, 데이타라인 (33)과 연결되는 다수의 팬아우트라인(33a)중에 단선된 팬아우트라인(39)이 다른 팬아우트라인에 단락된 경우이다.Meanwhile, according to the second embodiment of the present invention, as illustrated in FIG. 5, the fan out line 39 disconnected among the plurality of pan out lines 33 a connected to the data line 33 is short-circuited to other pan out lines. If it is.
이러한 경우에, 단락된 팬아우트라인(39)과 다른 팬아우트라인(33a)사이를 레이저를 이용한 절단(43)을 한다음 절단된 팬아우트라인(39)의 양측 부분에 상기 팬아우트라인(33a)과는 다른 금속으로 된 리페어라인(43)을 연결한다. 이때, 연결하는 방법은 본 발명의 제1실시예와 동일하다.In this case, a laser cut 43 is performed between the shorted pan out line 39 and the other pan out lines 33 a, and then, on both sides of the cut pan out lines 39, the pan out line 33 a is different from the pan out lines 33 a. The repair line 43 made of metal is connected. At this time, the connection method is the same as the first embodiment of the present invention.
상기 구성에서와 같이, 리페어라인은 단락이나 단선 등이 없을 때에는 팬아우트 금속과는 플로팅(floating)되어 있는 상태이기 때문에 리페어라인 형성에 따른 화면품위 저하 등이 문제가 발생하지 않는다.As in the above configuration, since there is no short circuit or disconnection, the repair line is in a floating state with the fan-out metal, so that the deterioration of the screen quality due to the repair line formation does not occur.
또한편, 본 발명의 제3실시예에 의하면, 도 6에 도시된 바와같이, 본 발명의 제1실시예와 동일하게, 데이타라인(53)과 연결되는 다수의 팬아우트라인(53a)중에 단선된 팬아우트라인(59)이 포함된 경우이다.In addition, according to the third embodiment of the present invention, as shown in Fig. 6, the same as the first embodiment of the present invention, the disconnection among the plurality of panout lines 53a connected to the data line 53 is disconnected. This is the case when the pan out line 59 is included.
또한, 상기 단선된 팬아우트라인(59)의 양측 각각에 제1리페어라인(61)과 제2리페어라인(63)이 서로 대향되게 연결되어 있다.In addition, the first repair line 61 and the second repair line 63 are connected to both sides of the disconnected fan out line 59 so as to face each other.
상기 구성에서와 같이, 제1리페어라인(61)과 제2리페어라인(63)을 서로 반대방향으로 각각 상기 팬아우트라인(53a)에 연결시켜 주므로써 불량이 발생한 위치에 따라 리페어라인의 저항이 감소하는 방향으로 리페어하는 구조를 적용할 수 있다.As in the above configuration, by connecting the first repair line 61 and the second repair line 63 to the fan out line 53a in opposite directions, respectively, the resistance of the repair line decreases according to the position where the defect occurs. It is possible to apply a structure to repair in the direction.
한편, 본 발명의 제4실시예에 의하면, 도 7에 도시된 바와같이, 데이타라인 (73)과 연결되는 다수의 팬아우트라인(73a)중에 단선된 팬아우트라인(79)이 데이터OLB패드(71)내에 포함된 경우이다.Meanwhile, according to the fourth embodiment of the present invention, as illustrated in FIG. 7, the fan out line 79 disconnected among the plurality of fan out lines 73a connected to the data line 73 is connected to the data OLB pad 71. It is included in the case.
또한, 리페어라인(81)이 데이터OLB패드(71)와 스크라이브라인(B)사이에 형성시켜 데이터OLB패드(71)내에 발생한 단선 등의 불량을 리페어하도록 되어 있다.In addition, a repair line 81 is formed between the data OLB pad 71 and the scribe brain B to repair defects such as disconnection occurring in the data OLB pad 71.
이러한 경우에, 리페어는 팬아우트부의 불량을 리페어하던 방법과 동일한 방법으로 데이터OLB패드(71)내의 불량도 수리할 수 있다.In this case, the repair can also repair the defect in the data OLB pad 71 in the same manner as the method of repairing the defect of the fan outlet portion.
그리고, 상기 데이터OLB패드(71)와 스크라이브라인(B)간의 간격은 0.5 mm로 스크라이브라인 형성공정이 끝난 후에도 약 0.3 mm 의 공간이 존재하기 때문에 리페어라인을 형성하는데 지장이 없다.In addition, since the space between the data OLB pad 71 and the scribe brine B is about 0.5 mm, there is no problem in forming a repair line since the space of about 0.3 mm exists even after the scribe brine forming process is completed.
상기에서 설명한 바와같이, 본 발명에 따른 리페어라인이 형성된 액정표시장치 및 그 제조방법에 있어서는 다음과 같은 효과가 있다.As described above, the liquid crystal display device having the repair line according to the present invention and the manufacturing method thereof have the following effects.
본 발명에 의하면, 데이터라인 또는 게이트라인에 연결된 팬아우트부에 리페어라인을 형성하므로써 팬아우트라인간에 단선이 발생하더라도 리페어라인과 단선된 라인을 쇼트시켜 선결함을 수리할 수 있다.According to the present invention, by forming a repair line in the fan outlet connected to the data line or the gate line, even if a disconnection occurs between the fan outlines, the repair line can be repaired by shorting the repair line and the disconnected line.
또한, 본 발명에 의하면, 단락이 발생하더라도 레이저 절단후 팬아우트라인에 리페어라인을 형성하므로써 단락에 의한 설결함을 수리할 수 있다.In addition, according to the present invention, even if a short circuit occurs, by forming a repair line in the fan out line after laser cutting, it is possible to repair the formation of the short circuit.
그리고, 이렇게 형성된 리페어라인은 결함이 없는 경우에는 팬아우트라인과는 플로팅되어 있기 때문에 화면품위에는 전혀 지장을 주지 않는다.In the case where the repair line is formed in this way, the repair line is floated with the pan outline so that the screen quality is not impaired at all.
