Description
본 발명은 액정표시소자(LCD ; Liquid Crystal Display Device)에 관한 것으로, 특히 액정주입구의 댐(dam)을 다중선상에 형성하는 액정패널의 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device (LCD), and more particularly, to a method of manufacturing a liquid crystal panel in which dams of liquid crystal inlets are formed on multiple lines.
평판 디스플레이 중에서 액정표시소자는 박형, 저가, 저소비 전력, 풀컬러화(full color)가 용이하다는 등의 특징 때문에 그 비중이 점차 증대되고 있다.Among flat panel displays, the liquid crystal display device is gradually increasing its weight due to features such as thin, low cost, low power consumption, and easy full color.
상기 액정표시소자의 액정패널은 제 1 기판과, 상기 제 1 기판에 대향 합착된 제 2 기판과, 상기 제 1 ,제 2 기판 사이에 형성된 액정층으로 구성되는데, 상기와 같이 구성되는 액정패널에 액정을 주입하는 방법으로는 섬유 소재를 이용한 얀(yarn) 방식, 보트(boat) 방식 및 딥(dip) 방식이 있다.The liquid crystal panel of the liquid crystal display device is composed of a first substrate, a second substrate opposed to the first substrate, and a liquid crystal layer formed between the first and second substrates. Liquid crystal injection methods include a yarn method, a boat method, and a dip method using a fiber material.
얀 방식은 섬유소재인 얀을 액정에 담궈서 충분한 양의 액정을 흡수시킨 다음, 상기 얀을 액정표시소자에 형성된 액정 주입구에 근접시키면, 액정표시소자의 내부에 미리 형성된 진공압과 모세관 현상에 의한 흡인력으로 액정이 액정 패널 내부로 주입되는 방식이다. 한편, 보트 방식은 얀을 채용하지 않고, 액정 주입구에 직접 액정을 부어서 주입하는 방식이고, 딥 방식은 액정이 가득찬 트레이에 액정 주입구를 담그어 주입하는 방식이다.The yarn method absorbs a sufficient amount of liquid crystal by immersing a yarn, which is a fiber material, in a liquid crystal, and then closes the yarn to a liquid crystal injection hole formed in the liquid crystal display device. The liquid crystal is injected into the liquid crystal panel. On the other hand, the boat method is a method in which the liquid crystal is poured directly into the liquid crystal injection hole without using a yarn, and the dip method is a method of dipping and injecting the liquid crystal injection hole into a tray full of liquid crystal.
따라서, 액정표시소자에는 액정을 주입하기 위한 액정 주입구가 형성되어야 한다.Therefore, a liquid crystal injection hole for injecting liquid crystal should be formed in the liquid crystal display device.
이하, 첨부된 도면을 참조하여 종래 기술에 따른 액정패널의 제조방법을 설명하면 다음과 같다.Hereinafter, a manufacturing method of a liquid crystal panel according to the prior art will be described with reference to the accompanying drawings.
도 1은 종래 기술에 의한 액정 주입구를 나타낸 평면도이다.1 is a plan view showing a liquid crystal injection hole according to the prior art.
일반적으로, 액정표시소자의 제조에 사용되는 액정 패널을 제조함에 있어서, 먼저 컬러필터층이 형성된 상부기판과 박막트랜지스터가 형성된 하부기판을 제조하고, 다음 상기 상, 하부기판에 투명도전막을 형성한다.In general, in manufacturing a liquid crystal panel used for manufacturing a liquid crystal display device, first, an upper substrate on which a color filter layer is formed and a lower substrate on which a thin film transistor is formed are manufactured, and then a transparent conductive film is formed on the upper and lower substrates.
이후, 상, 하부기판의 내측면에 형성된 투명도전막 상부에 폴리이미드와 같은 고분자 유기 배향막을 도포하여 러빙 처리한다. 이후, 상하 유리기판이 일정간격(5∼7㎛)으로 유지되도록 스페이서(spacer)를 섞은 열경화성 씨일제(seal)를 하부 유리기판에 인쇄하고, 상하 유리기판을 합착한 다음, 상기 씨일제를 열경화시킨다.Thereafter, a rubbing treatment is performed by coating a polymer organic alignment layer such as polyimide on the transparent conductive layer formed on the inner side of the upper and lower substrates. Thereafter, a thermosetting sealant mixed with spacers is printed on the lower glass substrate so that the upper and lower glass substrates are maintained at a predetermined interval (5 to 7 μm), the upper and lower glass substrates are bonded, and then the sealant is heated. Harden.
여기서, 상기 씨일제 인쇄는 도 1에서와 같이 한다. 즉, 액정 주입구 부분을 제외한 나머지 부분에는 빈틈없이 씨일제(11)를 인쇄하고 액정 주입구 부분에는 액정 주입구 선상을 따라 등간격으로 복수개의 댐(13)을 형성하여 이후 액정 주입시 그 흐름이 고르도록 한다.Here, the seal printing is performed as in FIG. 1. That is, the sealant 11 is printed on the remaining portions except for the liquid crystal injection hole, and a plurality of dams 13 are formed on the liquid crystal injection hole at equal intervals along the line of the liquid crystal injection hole so that the flow is even during the liquid crystal injection. do.
마지막으로 상기 액정패널을 원하는 크기로 절단하고, 액정 주입구를 통하여 모세관 현상과 압력차를 이용하여 액정을 주입한다. 그리고 상기 액정이 흘러나오지 않게 액정 주입구를 막음으로 소정의 액정패널을 완성한다.Finally, the liquid crystal panel is cut to a desired size, and the liquid crystal is injected using a capillary phenomenon and a pressure difference through the liquid crystal injection hole. And a predetermined liquid crystal panel is completed by blocking the liquid crystal injection hole so that the liquid crystal does not flow out.
그러나, 상기와 같은 종래의 액정패널의 제조방법은 다음과 같은 문제점이 있다.However, the conventional manufacturing method of the liquid crystal panel as described above has the following problems.
즉, 액정 주입구의 댐을 일직선상에 형성하면, 댐을 통과하는 액정의 속도에 비해 댐을 통과한 직후의 액정의 속도가 커져서 액정이 급속도로 확산한다.That is, when the dam of the liquid crystal injection port is formed in a straight line, the speed of the liquid crystal immediately after passing through the dam becomes larger than the speed of the liquid crystal passing through the dam, and the liquid crystal diffuses rapidly.
이러한 속도의 차이로 인해 액정 주입구의 폴리이미드막이 손상되어 액정 주입구 부분에 얼룩이 발생되므로서, 화질 저하가 유발된다.Due to such a difference in speed, the polyimide film of the liquid crystal injection hole is damaged and stains are generated in the liquid crystal injection hole, thereby degrading image quality.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로 액정주입구의 댐을 다중선상에 형성하는 액정패널의 제조방법을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, and an object thereof is to provide a method for manufacturing a liquid crystal panel in which a dam of the liquid crystal inlet is formed on a multiple line.

And forming a liquid crystal into the liquid crystal injection hole.
이하, 첨부된 도면을 참조하여 본 발명의 실시예에 의한 액정패널의 제조방법을 상세히 설명하면 다음과 같다.Hereinafter, a method of manufacturing a liquid crystal panel according to an embodiment of the present invention with reference to the accompanying drawings in detail as follows.
제 1 실시예First embodiment
도 2는 본 발명의 제 1 실시예에 의한 액정 주입구를 나타낸 평면도이다.2 is a plan view illustrating a liquid crystal injection hole according to a first exemplary embodiment of the present invention.
본 발명의 제 1 실시예에 따른 액정패널의 제조방법은 먼저, 제 1 기판에 색상을 표현하기 위한 RGB의 컬러필터층, 상기 RGB의 혼색을 방지하기 위한 블랙 매트릭스 및 공통전극을 형성하여 컬퍼필터기판을 완성하고, 제 2 기판에 화소단위를 구분짓는 데이터 배선 및 게이트 배선과, 상기 단위 화소 내에 박막트랜지스터 및 화소전극을 형성하여 박막트랜지스터 기판을 완성한다.In the manufacturing method of the liquid crystal panel according to the first embodiment of the present invention, first, a color filter layer of RGB for expressing color on the first substrate, a black matrix and a common electrode to prevent the mixed color of the RGB are formed to form a culper filter substrate. Next, data lines and gate lines for dividing pixel units on the second substrate, and thin film transistors and pixel electrodes are formed in the unit pixels to complete the thin film transistor substrate.
다음, 상기 제 1 ,제 2 기판의 공통전극 및 화소전극 상부에 폴리이미드 등의 배향막을 얇고 균일하게 도포한 뒤, 기계적 러빙을 이용하여 일정 방향으로 직선홈을 형성한다.Next, an alignment layer such as polyimide is applied to the common electrode and the pixel electrode of the first and second substrates thinly and uniformly, and then linear grooves are formed in a predetermined direction by using mechanical rubbing.
이후, 상기 제 1 기판과 제 2 기판이 일정하게 이격되도록 스페이서를 균일하게 뿌려주고, 상기 제 1 기판 상에 씨일제를 형성하여 상기 제 1기판과 제 2 기판을 대향 합착시킨다.Thereafter, the spacers are evenly sprayed so that the first substrate and the second substrate are uniformly spaced apart, and a sealant is formed on the first substrate so that the first substrate and the second substrate are opposed to each other.
이 때, 씨일제는 도 2에서와 같이 인쇄한다. 즉, 액정 주입구를 제외한 나머지 부분은 빈틈없이 봉하고 액정 주입구는 종래와 달리 다중선상에 등간격으로 복수개의 댐(23)을 형성한다.At this time, the sealant is printed as in FIG. 2. That is, the remaining portion except for the liquid crystal injection hole is tightly sealed, and the liquid crystal injection hole forms a plurality of dams 23 at equal intervals on a multiple line, unlike the conventional art.
즉, 액정주입구의 바깥선상에 메인댐을 형성하고 상기 메인댐과 메인댐 사이에 상응하도록 내측선상에 복수개의 또다른 댐을 형성한다.That is, the main dam is formed on the outer line of the liquid crystal inlet, and a plurality of further dams are formed on the inner line so as to correspond between the main dam and the main dam.
그리고, 상기 각 댐의 높이는 씨일제(21)의 높이와 동일하게 하여, 상기 댐(23)에 의해서도 셀 갭이 유지되도록 한다.In addition, the height of each dam is the same as the height of the sealant 21, so that the cell gap is also maintained by the dam 23.
상기에서와 같이 다중선상에 댐을 형성하면 상기 댐 사이를 통과하는 액정의 속도와 댐을 통과한 직후의 액정과의 차이가 최소화되어 이로인한 액정 주입구 부근의 배향막 손상이 최소화된다.As described above, when the dam is formed on the multi-line, the difference between the speed of the liquid crystal passing between the dams and the liquid crystal immediately after passing through the dam is minimized, thereby minimizing damage to the alignment layer near the liquid crystal injection hole.
마지막으로, 상기 액정패널을 원하는 크기로 절단하고, 액정 주입구를 통하여 모세관 현상과 압력차를 이용하여 액정을 주입한다. 그리고 상기 액정이 흘러나오지 않게 액정 주입구를 막아서 소정의 액정패널을 완성한다.Finally, the liquid crystal panel is cut to a desired size, and the liquid crystal is injected using a capillary phenomenon and a pressure difference through the liquid crystal injection hole. Then, the liquid crystal injection port is blocked to prevent the liquid crystal from flowing out, thereby completing a predetermined liquid crystal panel.
제 2 실시예Second embodiment
도 3은 본 발명의 제 2 실시예에 의한 액정 주입구를 나타낸 평면도이다.3 is a plan view illustrating a liquid crystal injection hole according to a second exemplary embodiment of the present invention.
본 발명의 제 2 실시예에 따른 액정패널의 제조방법은 먼저, 제 1 기판에 컬러필터층, 블랙 매트릭스 및 공통전극을 형성하여 컬퍼필터 기판을 완성하고, 제 2 기판에 화소단위를 구분짓는 데이터 배선 및 게이트 배선과, 상기 단위 화소 내에박막트랜지스터 및 화소전극을 형성하여 박막트랜지스터 기판을 완성한다.In the method of manufacturing a liquid crystal panel according to the second embodiment of the present invention, first, a color filter layer, a black matrix, and a common electrode are formed on a first substrate to complete a culffer filter substrate, and data wirings for dividing the pixel units on the second substrate. And a thin film transistor and a pixel electrode formed in the gate wiring and the unit pixel to complete the thin film transistor substrate.
다음, 상기 제 1 ,제 2 기판의 공통전극 및 화소전극 상부에 유기 고분자 배향막을 균일하게 도포한 뒤, 러빙 처리한다.Next, the organic polymer alignment layer is uniformly coated on the common electrode and the pixel electrode of the first and second substrates, and then rubbed.
이후, 상기 제 1 기판과 제 2 기판이 일정하게 이격되도록 스페이서를 균일하게 뿌려주고, 상기 제 1 기판상에 씨일제를 인쇄하여 상기 제 1기판에 대향되게 상기 제 2 기판을 합착시킨다.Thereafter, the spacers are evenly sprayed to uniformly space the first substrate and the second substrate, and a sealant is printed on the first substrate to bond the second substrate to face the first substrate.
이 때, 씨일제(31)는 도 3에서와 같이 인쇄한다. 특히, 액정 주입구에는 일직선상으로 형성된 댐(33)의 내측선상에 배리어(barrier) 막(35)을 더 형성시켜 액정이 급속도로 주입되는 것을 저지시킨다.At this time, the sealant 31 is printed as shown in FIG. In particular, a barrier film 35 is further formed on the inner line of the dam 33 formed in a straight line in the liquid crystal injection hole to prevent the liquid crystal from being injected rapidly.
상기에서와 같이 댐(33) 앞에 배리어 막(35)을 형성하면 상기 댐 사이를 통과하는 액정의 속도와 댐을 통과한 직후의 액정과의 차이가 최소화되어 이로인한 액정 주입구 부근의 배향막 손상이 최소화된다.As described above, when the barrier layer 35 is formed in front of the dam 33, the difference between the speed of the liquid crystal passing between the dams and the liquid crystal immediately after passing the dam is minimized, thereby minimizing damage to the alignment layer near the liquid crystal injection hole. do.
마지막으로, 상기 액정패널을 원하는 크기로 절단하고, 액정 주입구를 통하여 액정을 주입한다. 그리고 상기 액정이 흘러나오지 않게 액정 주입구를 막아서 소정의 액정패널을 완성한다.Finally, the liquid crystal panel is cut to a desired size and liquid crystal is injected through the liquid crystal injection hole. Then, the liquid crystal injection port is blocked to prevent the liquid crystal from flowing out, thereby completing a predetermined liquid crystal panel.
상기와 같은 본 발명의 액정패널의 제조방법은 다음과 같은 효과가 있다.The manufacturing method of the liquid crystal panel of the present invention as described above has the following effects.
즉, 액정 주입구의 댐을 다중선상에 형성하여 댐을 통과하는 액정의 속도와 댐을 통과한 직후의 액정의 속도와의 차를 줄여 이후 액정 주입시, 액정 주입구 부근의 배향막 손상이 최소화되게 한다. 따라서, 화면에 얼룩이 생기지 않아 액정표시소자의 화질에 대한 신뢰도가 높아진다.That is, the dam of the liquid crystal injection hole is formed on the multi-line to reduce the difference between the speed of the liquid crystal passing through the dam and the speed of the liquid crystal immediately after passing the dam to minimize the damage of the alignment film near the liquid crystal injection hole when the liquid crystal is injected. Therefore, the screen is not stained, and the reliability of the image quality of the liquid crystal display device is increased.
