본 고안은 액종표시소자에 관한 것으로서, 보다 상세하게는 양호한 표시부를 얻을 수 있는 액정표시소자에 관한 것이다.The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device in which a good display unit can be obtained.
전자제품이나 자동차 계기판 등에 사용되는 액정표시장치는, 상하부 기판의 투명전극간에 소정의 전압을 인가시켜 그 사이에 위치된 액정의 분자배열을 변화시킴으로써 빛의 선광방향에 따라 빛을 통과 또는 차단하여 소망하는 문자나 숫자 등을 얻고 있다.Liquid crystal display devices used in electronic products, automotive instrument panels, etc., by applying a predetermined voltage between the transparent electrodes of the upper and lower substrates, and changing the molecular arrangement of the liquid crystal positioned between them to pass or block the light according to the direction of the beneficiation of light I am getting letters and numbers.
이러한 액정표시장치는 기판에 전긍이 형성되고 배향막이 형성된 후 균일한 크기의 스페이서를 개재하여 1쌍의 기판이 조합되면, 상하 기판사이에 형성되는 주입구를 통하여 액정을 주입하는 방식으로 제작되고 있다.Such a liquid crystal display device is manufactured by injecting liquid crystal through an injection hole formed between upper and lower substrates when a pair of substrates are combined through a spacer having a uniform size after an electric potential is formed and an alignment layer is formed.
이와 같이 액정시소자는 액정을 주입하기 위한 주입구가 필연적으로 있어야 하는 구조적 특징을 갖는데, STN 액정표시장치는 이러한 주입구를 2개소에 형성하고 있다.As described above, the liquid crystal display device has a structural feature that an injection hole for injecting liquid crystal is inevitably required, and the STN liquid crystal display device has two injection holes.
제1도는 종래의 액정표시장치의 기판 평면도로서, 주변부에 시일재(1)가 도포되어 있고, 그 일측에 2개의 주입구(2)가 형성되어 있다.1 is a plan view of a substrate of a conventional liquid crystal display device, in which a sealing material 1 is applied to a peripheral portion thereof, and two injection holes 2 are formed on one side thereof.
이와 같은 구종의 액정표시장치는 2개의 주입구를 갖고 있으나, 그 면적이 측면에 비하여 너무 작기 때문에 액정주입이 충분히 되지 않는 문제점이 있다.This type of liquid crystal display device has two injection holes, but the liquid crystal injection is not sufficient because its area is too small for the side surface.
이를 해결하기 위하여 액정 주입구 면적을 기판의 1/2로 하는 방안이 제안되고 있으나, 이 방식은 액정주입이 원활히 행하여지는 이점은 있지만 주입구가 너무 크기 때문에 밀봉시 본드가 내측으로 쳐지는 현상이 나타나고 있다.In order to solve this problem, a method of reducing the area of the liquid crystal injection hole to 1/2 of the substrate has been proposed. However, the liquid crystal injection has the advantage of smoothly performing the liquid crystal injection. .
따라서 주입구에 본드와의 표면장력을 높여 처짐을 방지하기 위한 시일을 미세하게 하여 다수개 형성하고 있지만 만족할만한 효과를 얻지 못하고 있다.Therefore, a plurality of seals are formed in the inlet to increase the surface tension with the bond to prevent sag, but a satisfactory effect is not obtained.
본 고안은 상기한 바와 같은 종래 기술의 문제점을 해소하기 위하여 안출된 것으로서, 본 고안의 목적은 본드의 침투를 방지하여 표시부의 질을 높일 수 있는 액정표시장치를 제공하는데 있다.The present invention has been made to solve the problems of the prior art as described above, an object of the present invention is to provide a liquid crystal display device that can improve the quality of the display by preventing the penetration of the bond.
이를 실현하기 위하여 본 고안은 1쌍의 도전성 판넬사이에 액정을 주입하고 전기광학적 효과로 소정의 문자나 숫자등을 표시하는 액정표시장치에 있어서, 액정을 주입하기 위한 주입구 크기를 기판의 측면폭에 대하여 1/2로 함과 아울러 이 주입구에 직선부와 경상부로 이루어진 보조시일을 형성한 액정표시장치를 제공한다.In order to realize this, the present invention injects a liquid crystal between a pair of conductive panels and displays a predetermined letter or number by electro-optic effect. A liquid crystal display device is provided in which the auxiliary seal consisting of a straight portion and a mirror portion is formed in the injection hole.
이하 본 고안의 바람직한 실시예를 첨부한 도면에 따라 더욱 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
제2도는 본 고안에 의한 액정표시장치의 기판 평면도로서, 기판의 주변부에는 시일재(10)가 도포되어 있다.2 is a plan view of the substrate of the liquid crystal display device according to the present invention, and the sealing material 10 is coated on the periphery of the substrate.
기판의 일측면에는 시일재(10)가 일정거리만큼 도포되지 않은 주입구(11)가 형성되어 있는데, 이 주입구(11)의 폭은 기판의 1/2에 해당한다.An injection hole 11 is formed on one side of the substrate to which the sealing material 10 is not applied by a predetermined distance, and the width of the injection hole 11 corresponds to 1/2 of the substrate.
이 주입구(11)에는 본드 봉입시 본드의 과다침투를 방지하는 보조시일(12)이 다수개 형성되어 있다.The injection hole 11 is provided with a plurality of auxiliary seals 12 to prevent the excessive penetration of the bond when the bond is sealed.
이 보조시일(12)은 등간격으로 배치되고 있는데, 외측으로는 직선부(13)가 형성되어 있으며, 내측으로는 일정한 각도를 이루며 확개되어 있는 경사부(14)가 직선부(13)와 일체로 형성되어 있다.The auxiliary seals 12 are arranged at equal intervals, and the straight portion 13 is formed on the outer side, and the inclined portion 14 extending at a predetermined angle on the inner side is integrated with the straight portion 13. It is formed.
이와 같이 이루어지는 본 고안의 액정표시장치는, 상하기판이 조합되고 액정주입이 완료된 후, 주입구(11)를 밀봉시킬 때 본드를 주입구(11)내로 주입시키게 되는데, 이때 보조시일(12)에 의해 본드의 과다침투가 방지된다.In the liquid crystal display device according to the present invention, after the upper and lower substrates are combined and the liquid crystal injection is completed, the bond is injected into the injection hole 11 when the injection hole 11 is sealed, and the bond is performed by the auxiliary seal 12. Over-infiltration
특히 보조시일(12)의 내측부에 확개되어 있는 경사부(14)가 입구를 축소시키고 있기 때문에 본드의 침투를 억제하게 된다.In particular, since the inclined portion 14 that extends to the inner side of the auxiliary seal 12 reduces the inlet, the penetration of the bond is suppressed.
따라서 본드 과다침투에 의해 표시부 내의 질이 저하되는 것을 방지할수 있으며, 볼록렌즈 효과를 최대한 억제시킬 수 있어 양호한 디스플레이 상태를 실현할수 있다.Therefore, the quality in the display portion can be prevented from being degraded due to excessive bond penetration, and the convex lens effect can be suppressed to the maximum, thereby achieving a good display state.
이러한 액정표시장치는 특히 STN액정표시장치에 적합한 것으로서 볼록렌즈 효과에 의해 전압인가시 주입구 부분이 먼저 밝게 나타나는 현상을 방지할 수 있으며 액정주입을 충분히 할 수 있음은 물론 표시부내로의 본드 침입을 방지할 수 있어 보다 양호한 표시소자를 얻을 수 있는 이점이 있다.Such a liquid crystal display device is particularly suitable for the STN liquid crystal display device, and can prevent a phenomenon in which the injection hole is first brightened when the voltage is applied by the convex lens effect, and can sufficiently inject the liquid crystal and prevent bond intrusion into the display unit. There is an advantage that a better display element can be obtained.
