본 고안의 액정 표시소자에 관한 것으로, 특히 실프린터영역(seal printer area)을 설정하기 위한 실라인마크에 관한 것이다.The present invention relates to a liquid crystal display device, and more particularly, to a seal line mark for setting a seal printer area.
액정 표시소자는 일반적으로 두께가 얇고 소자자체의 전력소모가 극히 적기 때문에 전자계산기나 손목시계등 많은 분야에 이용되고 있으며, 최근에는 액정 색소를 첨갈하여 액정 TV를 생산하는등 그 기술 개발에 많은 연구가 진행되고 있다.Liquid crystal display devices are generally used in many fields such as electronic calculators and wristwatches because of their thin thickness and extremely low power consumption.In recent years, many studies have been conducted on the development of technology such as liquid crystal TV production by adding liquid crystal dyes. Is going on.
제1도는 일반적인 액정 표시소자를 단면도로 나타낸 것이며, 그 구성은 화소전극(3,9)이 코팅된 상하 2매의 유리기판(2,10)과 상기 유리판의 외부에 설치된 평광자(1,11)로 이루어지고, 상기 유리기판(2,10)은 접착제에 의하여 실라인(6)을 따라 내부가 밀봉되도록 접착되고 밀봉부(5)에는 액정이 주입된다. 미설명부호 4와 8은 전극(3,9)을 코팅하는 배향막이며, 7은 상하 유리기판을 압착하는 도전성 접착제이다.FIG. 1 is a cross-sectional view of a general liquid crystal display device, and its configuration includes two upper and lower glass substrates 2 and 10 coated with pixel electrodes 3 and 9 and flatteners 1 and 11 provided outside the glass plate. The glass substrates 2 and 10 are bonded together to seal the inside of the glass line 2 along the seal line 6 by an adhesive, and the liquid crystal is injected into the sealing part 5. Reference numerals 4 and 8 are alignment layers for coating the electrodes 3 and 9, and 7 is a conductive adhesive for pressing the upper and lower glass substrates.
액정의 분자는 액체와 같이 유동적이지만 규칙성을 가지고 있으며, 어느 한편으로 배향되어 있는 액정분자에 상기 화소전극(3,9)을 통하여 전계를 가하면 국부적으로 뷴자의 배향상타가 변화되고 입사광의 반사를 변화시킴으로서 외부에 숫자등이 나타나게 된다.The molecules of the liquid crystal are fluid but regular as liquid, and when the electric field is applied to the liquid crystal molecules oriented on the other hand through the pixel electrodes 3 and 9, the alignment phase of the letter is locally changed and the incident light is reflected. By changing the numbers will appear on the outside.
상기 액정 표시소자의 제조에 있어서는 전극이 형성된 유리기판(2,10)을 실라인(6)을 따라 접착하는 공정이 중요하다.In manufacturing the liquid crystal display device, a process of adhering the glass substrates 2 and 10 on which the electrodes are formed along the seal line 6 is important.
왜냐하면 상하 유리기판을 부착함에 있어서, 그 주변부가 완전히 밀봉되어야만 내부의 액정이 외부로 누출되지 않으며 유리기판에 실라인을 프린트할때에 실라인의 폭을 정확히 하여야만 액정 표시소자의 외부에서 실라인이 보이지 않기 때문이다. 결국 상하유리 기판을 실라인을 따라 접착하는 공정은 액정 표시소자의 신뢰성 및 수명이 크게 영향을 미치는 것으로 볼 수 있다.Because when attaching the upper and lower glass substrates, the liquid crystal inside should not be leaked to the outside until the periphery is completely sealed. Because it is invisible. As a result, the process of adhering the upper and lower glass substrates along the seal line can be considered to greatly affect the reliability and lifetime of the liquid crystal display.
이와 같은 이유로 실라인을 유리기판에 정확히 프린트하기 위하여 유리기판에 실라인마크를 미리 표시하고 상기 마크를 따라 실라인을 프린트하고 있다. 즉 제2도에서와 같이 상판 또는 하판의 유리기판(12)에 미리 실라인마크(15)를 표시하고 이 마크에 스크린 마스크를 맞춘 다음 스크린 마스크 위에 접합체를 부어 실라인이 정확히 프린트되도록 하고 있다.For this reason, in order to accurately print the seal line on the glass substrate, the seal line mark is displayed on the glass substrate in advance, and the seal line is printed along the mark. That is, as shown in FIG. 2, the seal line mark 15 is displayed on the glass substrate 12 of the upper plate or the lower plate in advance, the screen mask is aligned with the mark, and the bonded body is poured on the screen mask so that the seal line is correctly printed.
그러나, 종래의 실라인마크는 제2도에서와 같이 삼각형으로 표시되기 때문에 실라인 프린트후 유리기판을 합착하여 소성시킬때 플로우영역이 나타나지 않아 정확한 배열이 어렵고 프린트시 실라인이 마크와 잘 맞았다하더라도 플로우된 경우 외부 노출부분(viewing area) 또는 스크라이버영역(scriber area)을 침범했는지의 여부를 알 수가 없어 다음 공정에 문제가 따르고 신뢰도가 떨어진다.However, since the conventional seal line mark is displayed as a triangle as shown in Fig. 2, the flow area does not appear when the glass substrates are bonded and fired after the seal line printing, so that it is difficult to accurately arrange the seal line. If flowed, it is not known whether it has invaded the viewing area or the scriber area, which leads to problems with the next process and poor reliability.
본 고안은 상기한 문제점을 해결하기 위하여 안출한 것으로, 실라인 마크를 프린트영역과 플로우영역으로 표시하여 작업후 공정에서 프린트 상태를 쉽게 확인할 수 있고 배열이 잘못되었을 경우 이를 금방 확인하여 다음공정에 대처할 수 있도록 하는데에 그 목적이 있다.The present invention has been devised to solve the above problems, and it is possible to easily check the print state in the post-process by displaying the seal line mark in the print area and the flow area, and if the arrangement is wrong, it is possible to immediately cope with the next process. The purpose is to make it possible.
제3도는 유리기판에 본 고안의 실라인 마크가 표시된 것을 나타낸다. 본 고안의 실라인마크(15')는 프린트영역과 플로우영역을 표시하기 위하여형으로 표시되며, 여기에서 오목부는 프린트영역이 되고 양단의 블록부는 플로우 영역이 된다. 플로우영역은 플린트영역의 40-50% 범위로 설정하는 것이 바람직하다.3 shows that the seal line mark of the present invention is displayed on the glass substrate. The seal line mark 15 'of the present invention is used to indicate the print area and the flow area. The recessed portion becomes a print area and the block portions at both ends become a flow area. The flow area is preferably set in the range of 40-50% of the flint area.
액정 표시소자를 제조하는 과정은 다음과 같다. 상하 유리기판(2,10)에 전극(3,9)을 형성하고 배향막(4,8)을 코팅한 후, 상판 또는 하판의 유리기판에 본 고안의 실라인 마크(15')를 따라 실라인(6)을 프린트한다. 실라인을 프린트할 때 공차가 허용되지 않으므로 스크린마스크를 정확히 맞추어야 하며, 실라인이 프린트된 다음 상하 유리기판을 합착하여 소성한다. 스크린마스크를 정확히 맞추어 실라인을 프린트하더라도 소성시 실라인이 플로우영역에 침범하는 경우가 있으며, 본 고안에서와 같이 실라인마크를 표시하면 침범에 따른 오차의 범위를 쉽게 식별할 수 있으므로 공정 작업중에 발생하는 상기 문제점에 대하여 즉시 대처할 수 있다.The process of manufacturing the liquid crystal display device is as follows. After forming the electrodes 3, 9 on the upper and lower glass substrates 2, 10 and coating the alignment films 4, 8, the seal lines along the seal line marks 15 'of the present invention on the upper or lower glass substrates. Print (6). Since tolerances are not allowed when printing the seal line, the screen mask must be exactly aligned. After the seal line is printed, the upper and lower glass substrates are bonded and fired. Even if the seal line is printed with the correct screen mask, the seal line may invade the flow area during firing.If the seal line mark is displayed as in the present invention, the range of error due to the invasion can be easily identified. It is possible to immediately deal with the above-mentioned problem.
따라서 본 고안과 같이 실라인마크를 표시하고 이 마크를 따라 실을 프린트하면 액정 표시소자 제조시 불량률을 제거하여 수율을 향상시키고 소자의 신뢰도를 향상시킬 수 있게 된다.Therefore, as shown in the present invention, if the seal line mark is displayed and the seal is printed along the mark, the defect rate in manufacturing the liquid crystal display device can be eliminated to improve the yield and improve the reliability of the device.
