본 고안은 액정표시소자에 관한 것으로서, 특히 전면판과 배면판 사이에 주입되는 액정의 누설을 방지하기 위하여 도포되는 시일재의 개선에 관한 것이다.The present invention relates to a liquid crystal display device, and more particularly, to an improvement of a sealing material applied to prevent leakage of liquid crystal injected between a front plate and a back plate.

액정의 분자배열 상태에 따라 표시패턴의 가시화가 이루어지는 액정표시소자는 전 반사형으로 전면판을 통하여 입사되는 광이 액정층을 지나 배면판을 통하여 재반사되는 형태의 것과, 배경광이 배면판을 지나 액정층을 통과한 후 전면판을 통해 투과되게 하는 형태의 것이 있다.The liquid crystal display device in which the display pattern is visualized according to the molecular arrangement state of the liquid crystal is a total reflection type in which light incident through the front plate passes back through the liquid crystal layer and is reflected back through the back plate. After passing through the liquid crystal layer there is a form that allows the transmission through the front plate.

제1도는 이러한 액정표시소자중 전자의 것을 나타내 보였다. 이것은 전면판(1)과 배면판(2)의 외측표면에 편광판(3) (3')이 설치되고 그 내면에는 소정패턴의 전극이 (4) (4')들이 형성되며 그 상부에는 액정분자를 소정방향으로 배향시키는 액정 배향막(5) (5')이 형성된다.1 shows the former of these liquid crystal display devices. It is provided with polarizing plates 3, 3 'on the outer surfaces of the front plate 1 and the back plate 2, and the electrodes having a predetermined pattern (4) and 4' are formed on the inner surface thereof, and liquid crystal molecules on the upper side thereof. The liquid crystal aligning film 5 (5 ') which orients this in a predetermined direction is formed.

그리고 상기 전면판(1)과 배면판(2)의 내면 가장자리에는 시일재(6) 즉, 열 또는 광경화성 에폭시 수지가 그 가장자리를 따라 제2도에 도시된 바와같이 직선으로 도포되어 이들을 집착함으로써 이들 사이에 소정의 폐쇄 공간이 형성되고 이폐쇄 공간에는 액정(7)이 주입된다.In addition, the inner surface edges of the front plate 1 and the back plate 2 are coated with a sealing material 6, that is, a heat or photocurable epoxy resin in a straight line, as shown in FIG. A predetermined closed space is formed between them, and the liquid crystal 7 is injected into the closed space.

이러한 액정표시소자는 상기 배면판(2)과 전면판(1)에 형성된 전극(4) (4')에 선택적으로 소정의 전위가 인가됨으로써 액정(7)이 배열되어 화상을 이루게 된다.In the liquid crystal display device, a predetermined potential is selectively applied to the electrodes 4 and 4 'formed on the back plate 2 and the front plate 1, so that the liquid crystals 7 are arranged to form an image.

근래에 와서는 이러한 액정표시소자가 점차 대형화로 되가는 추세에 있는바, 이같이 대형의 액정표시 소자에 있어서는 상기 전면판(10)과 배면판(2)사이의 접착력을 강화하기 위하여 상기 시일재(6)의 폭(W)을 넓히지않을 수 없게 된다. 그러나 제2도에 도시된 바와같이 상기 시일재(6)의 폭(W)을 넓일 경우 유효화면(10)이 상대적으로 좁아지게 되어 시각특성이 떨어지게 되는 문제점이 있다.In recent years, such a liquid crystal display device is gradually increasing in size. In such a large liquid crystal display device, in order to enhance the adhesive force between the front plate 10 and the back plate 2, It becomes impossible to widen the width W of 6). However, as shown in FIG. 2, when the width W of the seal member 6 is widened, the effective screen 10 is relatively narrowed, resulting in a drop in visual characteristics.

본 고안은 상기의 문제점을 해소하기 위하여 안출된 것으로서 대형의 액정표시 소자에 있어서 유효화면을 좁히지 않고도 접착력이 강화되도록 된 액정표시 소자를 제공하는데 그 목적이 있는 것이다.An object of the present invention is to provide a liquid crystal display device which is designed to solve the above problems and to enhance adhesion without narrowing an effective screen in a large liquid crystal display device.

상기 목적을 달성하기 위하여 액정이 개입되는 전면판과 배면판, 상기 액정이 누설되지 않도록 상기 전면판과 배면판 사이에 개재되는 시일재, 상기 전면판과 배면판의 양 외측면에 마련되는 편광판을 구비하여 된 액정표시소자에 있어서, 상기 시일재가 상기 전면판과 배면판의 가장자리에 파상형으로 형성된 것을 특징으로 한다.In order to achieve the above object, a front plate and a back plate through which a liquid crystal is interposed, a sealing material interposed between the front plate and a back plate so that the liquid crystal does not leak, and polarizing plates provided on both outer surfaces of the front plate and the back plate. In the liquid crystal display device provided, it is characterized in that the sealing material is formed in the shape of a wave shape on the edge of the front plate and the back plate.

본 고안의 특징에 의하면 상기 시일재가 얇은 폭으로 꾸불꾸불하게 도포되어 있으므로 상기 전면판과 배면판 사이에 부착 면적을 넓힐 수 있어서 대형의 액정표시 소자에 있어서도 유효화면의 폭을 좁히지 않고도 접착력을 강화할 수 있게 된다.According to a feature of the present invention, since the sealing material is coated with a thin width, the adhesion area can be widened between the front plate and the back plate, so that even in a large liquid crystal display device, the adhesive force can be enhanced without narrowing the effective screen width. Will be.

이하 첨부된 도면을 참조하면서 본 고안에 따른 바람직한 일실시예를 상기 전반사형 액정표시 소자를 예로들어 설명한다. 이는 제1도에 도시된 바와같이 전면판(1)과 배면판(2)의 외측표면에 편광판(3) (3')이 설치되고 그 내면에는 소정패턴의 전극(4) (4')들이 형성되며 그 상부에는 액정분자를 소정방향으로 배면시키는 액정 배향막(5) (5')이 형성된다. 그리고 상기 전면판(1)과 배면판(2)의 내면 가장자리에는 시일재(16)즉, 열 또는 광경화성 에폭시수지가 도표되어 이들을 접착함으로써 이들 사이에 소정의 폐쇄공간이 형성되고 이 폐쇄공간에는 액정(7)이 주입되어 있다.Hereinafter, a preferred embodiment according to the present invention will be described with reference to the accompanying drawings by taking the total reflection type liquid crystal display device as an example. As shown in FIG. 1, the polarizing plates 3 and 3 'are provided on the outer surfaces of the front plate 1 and the back plate 2, and the electrodes 4 and 4' of a predetermined pattern are formed on the inner surface thereof. The liquid crystal aligning film 5 (5 ') which forms the liquid crystal molecule in the predetermined direction is formed thereon. In addition, the inner surface edges of the front plate 1 and the back plate 2 are provided with a sealing material 16, that is, a thermal or photocurable epoxy resin, and the adhesives are formed to form a predetermined closed space therebetween. The liquid crystal 7 is injected.

여기서 상기 시일재(16)는 본 고안의 특징적 요소로서 제3도에 도시된 바와같이 상기 전면판(1)과 배면판(2)사이의 가장자리에 꾸불꾸불하게 도포하였다. 이때 상기 시일재(16)는 그 폭(D)을 종래 시일재의 폭(W)보다 비교적 적게 그리고 꾸불꾸불하게 도포하여 부착면적을 넓게함으로써 그 도포구간폭(B)을 적게 함에도 불구하고 접착강도가 강화되도록 하였다.Here, the sealing material 16 is applied to the edge between the front plate 1 and the back plate 2 as shown in Figure 3 as a characteristic element of the present invention. At this time, the sealing material 16 is applied to the width (D) relatively less and steadily than the width (W) of the conventional sealing material to increase the adhesion area despite the width of the application area (B) to reduce the adhesive strength It was to be strengthened.

이상에서와 같이 본 고안에 따른 액정표시 소자는 시일재(16)를 꾸불꾸불하게 도포함으로써 그 도포구간폭(B)을 적게하여도 부착면적이 넓어져 접착강도가 커지므로, 종래 대형의 액정표시소자에 있어 접착강도를 크게하기 위해 시일재(6)의 폭(W)을 넓게함으로써 유효화면(10)이 상대적으로 좁게되는 문제점이 있었던 것과는 달리, 유효화면(20)을 좁히지 않고도 대형의 액정표시소자를 유지할 수 있게 된다.As described above, the liquid crystal display device according to the present invention is coated with the sealing material 16 steadily, so that even if the application section width (B) is reduced, the adhesion area becomes wider, and thus the adhesive strength becomes large. In contrast to the problem that the effective screen 10 is relatively narrowed by widening the width W of the sealing material 6 in order to increase the adhesive strength in the device, a large liquid crystal display without narrowing the effective screen 20. The device can be held.

상술한 바와같이 본 고안은 대형의 액저이표시 소자에 있어 그 유효화면을 좁히지 않고도 접착강도를 유지하여 시각 특성이 좋은 액정표시소자를 제공함으로 제품의 상품적 가치를 높이는 효과적인 고안인 것이다.As described above, the present invention is an effective design to increase the product value of a product by providing a liquid crystal display device having good visual characteristics by maintaining the adhesive strength without narrowing the effective screen of a large liquid crystal display device.
