1a, 1b : 유리기판 2 : 봉지제1a, 1b: glass substrate 2: encapsulant

3 : 보조용 봉지제3: auxiliary sealing agent

본 발명은 액정 표시소자의 제조방법에 관한것으로, 특히 기판간격을 일정하게 유지시키도록 하기위해 보조용 봉지제를 사용하여 액정 표시소자를 제조하는 방법에 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 method for manufacturing a liquid crystal display device using an auxiliary encapsulant to maintain a constant substrate spacing.

제 1 도는 일반적인 액정 표시소자의 개략적 구조를 예시하고 있는 전개 사시도로서, 일반적인 액정표시소자는 투명전극을 갖는 제 1 유리기판(1b)과, 상기 투명전극에 대향하는 대향전극을 갖는 제 2 유리기판(1a)과, 이 기판들 사이에 삽입되어 있는 상기 양전극 간격을 소정의 방법으로 보호 유지토록 하는 스페이서(도면에 도시되어 있지 않음) 및 상기 양전극간에 액정이 봉입되도록 하는 봉지제(2)등으로 구성되어 있다.1 is an exploded perspective view illustrating a schematic structure of a general liquid crystal display device, in which a general liquid crystal display device includes a first glass substrate 1b having a transparent electrode and a second glass substrate having an opposite electrode facing the transparent electrode. (1a), a spacer (not shown) for protecting and maintaining the positive electrode gap inserted between the substrates in a predetermined manner, and an encapsulant (2) for enclosing the liquid crystal between the positive electrodes. Consists of.

그러나, 상기의 두 유리기판(1a)(1b)을 접합하기 위해 사용되는 봉지제(2)를 프린트 한 다음 조립하는 경우에는 봉지제 부근과 액정 셀(Cell) 내부와의 균일한 셀 갭(Cell gap) 유지가 어려웠다.However, when printing and assembling the encapsulant 2 used to bond the two glass substrates 1a and 1b, a uniform cell gap between the encapsulant and the inside of the liquid crystal cell is required. gap) was difficult to maintain.

즉, 보조용 봉지제를 사용하지 않고 단일의 봉지제(2)를 사용하여 대향되는 두 유리기판(1a)(1b)을 접합하는 종래의 방법으로는 균일한 셀갭의 유지가 곤란하였던 것이다.In other words, it was difficult to maintain a uniform cell gap in the conventional method of joining two glass substrates 1a and 1b opposed to each other using a single encapsulant 2 without using an auxiliary encapsulant.

그리고, 상기한 바와 같은 균일한 셀갭을 유지하기 위한 방법으로는 일본국 공개 특허공보(소화 58-100122)에 기재된 공지의 기술이 있는 바, 이는 투명전극을 손상시키지 않고 표시면 전체에 균일하게 스페이서를 배치하는 방법에 관한 것이었다.As a method for maintaining a uniform cell gap as described above, there is a known technique described in Japanese Laid-Open Patent Publication (Digestion 58-100122), which uniformly spacers the entire display surface without damaging the transparent electrode. Was about how to place it.

즉, 상기의 공개특허는 액정 셀의 균일한 셀갭을 유지시키는 수단으로 스페이서를 이용하였는 바, 이러한 기술은 스페이서의 배열이 봉지제의 도포보다는 어렵기 때문에 셀 갭 유지가 아울러 곤란하다는 결점이 있었다.That is, the above-mentioned patent uses a spacer as a means for maintaining a uniform cell gap of a liquid crystal cell. This technique has a drawback in that it is difficult to maintain a cell gap because the arrangement of the spacer is more difficult than the application of an encapsulant.

따라서, 본 발명은, 액정 표시소자의 셀갭을 용이하게 구현하기 위해, 유리기판상에 봉지제를 프린트시킬때 아울러 보조용 봉지제를 도포시킨 다음 대향되는 두 유리기판을 접합시키는 액정 표시소자의 제조방법을 제공하는데 그 목적이 있다.Accordingly, the present invention provides a method of manufacturing a liquid crystal display device in which an auxiliary encapsulant is applied to a glass substrate while printing an encapsulant on the glass substrate, and then bonding the two opposing glass substrates together. The purpose is to provide.

이하 제 2 도를 참조하여 본 발명의 실시예를 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 2.

상기 목적 및 제반이점을 달성시키기는 본 발명에 따른 기술적 수단은, 제 2 도에 도시되어 있는 바와같이, 일반적인 방법으로 봉지제(2)가 형성된 유리기판(1a)상에 보조용 봉지제(3)를 형성시킨 다음 대향되는 제1 및 제 2 유리기판을 접합하는 방법을 특징으로 한다.Technical means according to the present invention for achieving the above object and various advantages, as shown in Figure 2, the auxiliary encapsulant (3) on the glass substrate (1a) in which the encapsulant (2) is formed in a general manner (3). ) And then joining the opposing first and second glass substrates.

이와 같이, 유리기판상에 패턴형성 부분 및 봉지제(2) 형성부분 이외에는 즉 유리기판의 가장자리 부근에는, 실제로 제작완료된 제품과 상관없이, 별도의 지지대의 역할을 수행하는 기능을 갖는 보조용 봉지제(3)가 형성되어 있기 때문에 셀 내부와 봉지제 부근, 특히 유리기판의 가장자리의 부근에서 발생되는 셀 갭의 차이가 커지는 결점을 방지하게 되는 것이다.As described above, the auxiliary encapsulant having a function of serving as a separate supporter, in addition to the pattern forming portion and the encapsulant 2 forming portion on the glass substrate, that is, near the edge of the glass substrate, irrespective of the product actually manufactured ( Since 3) is formed, it is possible to prevent the drawback of a large difference in cell gap generated in the interior of the cell and near the encapsulant, particularly near the edge of the glass substrate.

따라서, 유리기판(1a)상에 봉지제(2) 및 이와 소정간격으로 보조용 봉지제(3)를 형성시킨 다음 대향된 유리기판(1b)과 접합시키고, 이어 유리기판의 컷팅(Cutting) 공정을 거쳐 보조용 봉지제(3)가 도포된 부분을 제거하면 균일한 셀갭의 유지된 액정 표시소자가 제작되는 것이다.Therefore, the encapsulant 2 and the auxiliary encapsulant 3 are formed on the glass substrate 1a at predetermined intervals, and then bonded to the opposing glass substrate 1b, followed by a cutting process of the glass substrate. By removing the portion to which the auxiliary encapsulant 3 is applied, a liquid crystal display device having a uniform cell gap is manufactured.

이상에서 설명한 바와 같이 본 발명에 의하면, 스페이서의 배치로 셀 갭을 유지하는 것이 아니라, 이보다 용이 하면서도 셀갭을 균일하게 형성시킬수 있는 이점이 있다.As described above, according to the present invention, the cell gap is not maintained by the arrangement of the spacers, but there is an advantage in that the cell gap can be formed more uniformly.
