본 고안은 액정표시소자에 관한 것으로서, 특히 배향막의 형성이 용이하고 그 형성두께 및 표면상태가 균일한 액정표시소자에 관한 것이다.The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device in which an alignment layer is easily formed and its thickness and surface state are uniform.
일반적으로 액정표시소자는 외부로부터 빛을 받아서 눈에 보이게 되는 수광형소자로서, 그 구조는 제1도에 도시되어 있는 바와 같다.In general, a liquid crystal display device is a light receiving device that receives light from the outside and is visible, and its structure is as shown in FIG.
이것은, 그 가장자리에 각각 도포된 실링재(5)에 의해 접착되어 액정(4)이 주입되는 소정의 폐쇄공간을 형성하는 전면판(1) 및 배면판(2)과, 상기 전면판(1) 및 배면판(2)의 내면에 소정의 패턴으로 형성된 전극(1a)(2a)들과, 상기 전극(1a)(2a)들의 상부에 위치되며 상기 폐쇄공간에 주입된 액정(4)의 분자를 소정의 방향으로 배향시키는 배향막(3')을 구비한다. 여기에서 상기 전극(1a)(2a)들의 상부에 형성된 배향막(3')은 전극(1a)(2a)들이 소정의 패턴으로 형성된 전면판(1)과 배면판(2)의 내면에 액상의 배향제를 스피너(spinner)나 옵셋트 프린트방식을 이용하여 배향막을 적충시키고, 이 배향막을 소정온도에서 열처리한 후 액정분자를 소정의 방향으로 배향시킬 수 있도록 상호 대향되는 각각의 표면을 소정의 각도로 러빙(rubbing)하여 형성한다.The front plate 1 and the back plate 2 are bonded to each other by a sealing material 5 coated on their edges to form a predetermined closed space into which the liquid crystal 4 is injected, and the front plate 1 and Electrodes 1a and 2a formed in a predetermined pattern on the inner surface of the back plate 2 and molecules of the liquid crystal 4 which are positioned above the electrodes 1a and 2a and injected into the closed space are prescribed. An alignment film 3 'oriented in the direction of is provided. Here, the alignment layer 3 ′ formed on the electrodes 1a and 2a has a liquid orientation on the inner surfaces of the front plate 1 and the back plate 2 on which the electrodes 1a and 2a are formed in a predetermined pattern. The spinner or offset printing method is used to fill the alignment layer, and the alignment layer is heat-treated at a predetermined temperature, and then the surfaces of the surfaces opposed to each other are aligned at a predetermined angle so that the liquid crystal molecules can be aligned in a predetermined direction. It is formed by rubbing.
그러나 이와 같이 형성된 종래 액정표시소자의 배향막은 먼저 스피너방식인 경우, 배향제가 확포 도포되는 두께가 일정하지 않고 도포된 배향제의 표면이 불균일하게 되어 제품의 특성을 저하시킬 뿐만 아니라 확표시 이물의 침투로 인한 불량 발생률이 높은 등의 작업상 어려운 문제점이 있었다. 그리고 옵셋트 프린트방식의 경우에는 특히 고가의 프린트기를 사용해야 하므로 시설비가 많이 소요되게 되는 문제점이 있었다.However, when the alignment layer of the conventional liquid crystal display device formed as described above has a spinner method, the thickness of the alignment agent is not widely applied, and the surface of the applied alignment agent becomes uneven, which not only lowers the characteristics of the product, but also penetrates the foreign matter. There was a difficult problem in operation, such as a high incidence of defective. In the case of offset printing, in particular, expensive printers have to be used, resulting in a large facility cost.
본 고안은 상술한 바와 같은 문제점들을 감안하여 안출된 것으로서, 배향막의 형성이 용이하고 그 형성두께 및 표면상태가 균일한 액정표시 소자를 제공함에 그 목적이 있다.The present invention has been made in view of the above problems, and an object thereof is to provide a liquid crystal display device having an easy formation of an alignment layer and a uniform thickness and surface state thereof.
상기의 목적을 달성하기 위하여 본 고안은, 전면판 및 배면판의 내면에 소정의 패턴으로 형성된 전극들과, 상기 전극들의 상부에 형성되는 배향막을 구비하여 된 액정표시소자에 있어서, 상기 배향막이 별도의 시이트상으로 제조되어 그 저면에 마련된 접착층에 의해 상기 전극들의 상부에 부착되도록 된 것을 특징으로 한다.In order to achieve the above object, the present invention is a liquid crystal display device comprising electrodes formed in a predetermined pattern on the inner surface of the front plate and the back plate, and an alignment layer formed on the electrodes, wherein the alignment layer is separate It is characterized in that the sheet is made of and adhered to the upper portion of the electrode by an adhesive layer provided on the bottom.
이하 첨부된 도면을 참조하여 본 고안에 따른 한 바람직한 실시예를 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제2도에는 본 고안에 따른 액정표시소자가 도시되어 있는 바, 이는 종래와 마찬가지로 그 가장자리에 각각 도포된 실링재(5)에 의해 접착되어 액정(4)이 주입되는 소정의 폐쇄공간을 형성하는 전면판(1) 및 배면판(2)의 내면에 소정의 패턴으로 형성된 전극(1a)(2a)들과, 상기 전극(1a)(2a)들의 상부에 위치되며 상기 폐쇄공간에 주입된 액정(4)의 분자를 소정의 방향으로 배향시키는 배향막(3)을 구비한다. 여기에서 상기 배향막(3)은 본고안의 특징에 따라 그 일측면에 접착층(3a)이 형성되어 상기 전극(1a)(2a)들이 형성된 전면판(1) 및 배면판(2)에 접착된다. 그리고 상기 접착층(3a)은 배향막(3)의 강도보다 약한 접착력을 가지며 상기 배향막(3)은 제3도에 도시된 바와 같이 견출지(6)에 시이트(sheet)상으로 별도 제작된다.FIG. 2 shows a liquid crystal display device according to the present invention, which, like the conventional one, is adhered by a sealing material 5 coated on each edge thereof to form a predetermined closed space into which a liquid crystal 4 is injected. Electrodes 1a and 2a formed in a predetermined pattern on the inner surfaces of the plate 1 and the back plate 2, and the liquid crystals 4 which are positioned above the electrodes 1a and 2a and injected into the closed space. The alignment film 3 which orientates the molecule | numerator of ()) to a predetermined direction is provided. In this case, the alignment layer 3 is attached to the front plate 1 and the back plate 2 on which the adhesive layer 3a is formed on one side thereof in accordance with the characteristics of the present invention, on which the electrodes 1a and 2a are formed. The adhesive layer 3a has a weaker adhesive force than the strength of the alignment layer 3, and the alignment layer 3 is separately manufactured in a sheet form on the holding paper 6 as shown in FIG. 3.
이와 같이 구성된 본 고안에 따른 액정표시소자는 견출지(6)에 시이트상으로 제작된 배향막(3)을 상기 견출지(6)로부터 분리하여 전극(1a)(2a)들이 형성된 전면판(1) 및 배면판(2)에 부착하도록 되어 있으므로 전면판(1)과 배면판(2)에 형성된 전극(1a)(2a)들에 배향막(3)의 형성이 용이할 뿐만 아니라 배향막(3)이 두께가 일정하고 그 표면이 균일한 상태로 형성되어 제품의 특성을 향상시킬 수 있게 된다. 따라서 종래에 발생되던 배향막의 두께 및 표면의 불균일로 인한 문제점과 배향막 형성시 작업상의 번거로움, 고가의 프린트기를 사용함에 따른 과다한 시설비등으로 인한 문제점이 해결되게 된다.The liquid crystal display device according to the present invention configured as described above has a front plate 1 and a back surface on which electrodes 1a and 2a are formed by separating an alignment film 3 formed in a sheet form on a holding paper 6 from the holding paper 6. Since it is attached to the plate 2, the alignment film 3 is easily formed on the electrodes 1a and 2a formed on the front plate 1 and the back plate 2, and the thickness of the alignment film 3 is constant. And the surface is formed in a uniform state it is possible to improve the characteristics of the product. Therefore, the problems caused by the thickness and surface unevenness of the alignment film, and the cumbersome work in forming the alignment film, and the problems caused by excessive facility costs due to the use of expensive printers are solved.
이상에서 설명한 바와 같이 본 고안의 액정표시소자는 견출지에 소정두께와 폭으로 제작된 배향막을 전면판 및 배면판의 전극들에 부착하여 액정표시소자의 배향막을 형성하도록 되어 있으므로 그 형성공정이 간단하고 형성된 배향막의 두께 및 표면이 균일하여 제품의 품질을 향상시킬 수 있게 된다.As described above, the liquid crystal display device of the present invention is formed by attaching an alignment film made of a predetermined thickness and width to the electrodes of the front plate and the back plate to form the alignment film of the liquid crystal display device. The thickness and the surface of the formed alignment film may be uniform to improve the quality of the product.
