Description
본 발명은 플라스틱 액정표시소자에 관한 것으로, 보다 상세하게는 구조적으로 플라스틱 기판과 편광판이 열에 의해 응력을 받게 되는 바, 기판 사이에 에폭시 수지를 도포하여 플라스틱 기판과 편광판의 응력을 보정하는 플라스틱 액정표시소자에 관한 것이다.The present invention relates to a plastic liquid crystal display device, and more particularly, a plastic liquid crystal display for structurally correcting a stress of a plastic substrate and a polarizing plate by applying an epoxy resin between the substrate and the plastic substrate and the polarizing plate being stressed by heat. It relates to an element.
액정표시소자는 외부로부터 인가되는 전압에 의해 액정의 꼬임각이 변화되는 유전이방성을 이용하여, 백라이트 혹은 외부로부터 조사된 광(光)을 선택적으로 투과시키거나 반대로 투과되지 않게 함으로써 문자나 숫자 및 화상을 표시하는 디스플레이 장치이다.The liquid crystal display device uses dielectric anisotropy in which the twist angle of the liquid crystal is changed by a voltage applied from the outside, and selectively transmits or transmits light irradiated from the backlight or the outside or vice versa. It is a display device for displaying.
이러한 액정표시소자는 시각 정보에 대한 다양한 요구와 미래형 디스플레이로서의 역할을 견지하기 위해, 초경량화 및 초슬림화되고 있다.In order to maintain various demands for visual information and a role as a future display, such liquid crystal display devices are being made ultra light and ultra slim.
이와 같은 결과로서 근래에는 폴리카보네이트와 같은 플렉시블한 플라스틱 필름을 사용하여 상, 하부의 기판을 구성한 플라스틱 액정표시소자가 소개되어 있는 바, 상기 플라스틱 액정표시소자의 사시도를 개략적으로 도 2에 도시하면 다음과 같다.As a result of this, in recent years, a plastic liquid crystal display device constituting upper and lower substrates using a flexible plastic film such as polycarbonate is introduced. A perspective view of the plastic liquid crystal display device is schematically shown in FIG. Same as
도면에서 보는 바와 같이 2매의 플라스틱 기판(2)(4)에 도시생략한 투명전극, 절연층 및 배향막을 형성하고, 실란트(6)를 이용하여 상, 하부의 기판(2)(4)을 상호 접착하므로 셀을 구성하는 것이며, 주입구를 통해 액정(8) 물질을 주입한 후 실(seal; 10)제를 이용하여 엔드 실링하므로 밀봉되어진다. 또한 각각의 상, 하부 기판의 외측에는 편광판(12)(14)이 부착된다.As shown in the figure, transparent electrodes, an insulating layer, and an alignment film, not shown, are formed on two plastic substrates 2 and 4, and the upper and lower substrates 2 and 4 are formed using the sealant 6. The cells are bonded to each other to form a cell, and after the liquid crystal 8 material is injected through the injection hole, it is sealed by end sealing using a sealant 10. In addition, polarizers 12 and 14 are attached to the outer side of each of the upper and lower substrates.
여기서 종래 플라스틱 액정표시소자는 상, 하부 기판을 접착하고 밀봉하는 수단으로서, 실란트(6)와 엔드 실(10)제를 사용하는 바, 실란트(6)는 보통 에폭시 수지 계열을 채용하고, 엔드 실제(10)로는 통상의 유리기판을 채용한 LCD에 사용하던 아크릴 수지와 같은 UV 경화제를 그대로 사용하고 있다.Here, the conventional plastic liquid crystal display device uses a sealant 6 and an end seal 10 agent as a means for adhering and sealing the upper and lower substrates. The sealant 6 generally adopts an epoxy resin series, In (10), UV curing agents such as acrylic resins used in LCDs employing ordinary glass substrates are used as they are.
상술한 구성의 플라스틱 액정표시소자는 실란트로 실링된 후 액정을 주입하고 엔드 실 공정을 거치면 열처리를 하게 된다. 상기와 같이 열처리과정을 거칠 때 플라스틱 기판은 특성상 글래스보다 열에 민감하여 팽창률 차이에 의해 휨 현상이 발생하게 된다.The plastic liquid crystal display device having the above-described configuration is heat-treated when the liquid crystal is injected after the sealant is sealed and subjected to the end seal process. When the heat treatment is performed as described above, the plastic substrate is more sensitive to heat than glass, so that warpage may occur due to a difference in expansion ratio.
플라스틱 기판이 휨 응력을 받게 되면 플라스틱 기판에 부착된 편광판도 휘게 되어 구조적으로 불안정하게 되며 신뢰성을 마치게 되면 그 응력이 더욱 커져 실란트만으로 지지가 불가능하고 이로 인해 기판이 깨져 액정이 유출될 수 있다.When the plastic substrate is subjected to bending stress, the polarizing plate attached to the plastic substrate is also bent and structurally unstable, and when the reliability is completed, the stress is increased so that only the sealant is impossible to support the liquid crystal.
상기 종래의 플라스틱 기판에 응력이 발생하는 형상을 도 3에 도시한다.The shape which a stress generate | occur | produces in the said conventional plastic substrate is shown in FIG.
도면에서 보면, 실란트(6)를 기준으로 액정(8)이 주입되어 있는 부분은 중앙으로 기판(2)(4)과 편광판(12)(14)이 휘고 상대적으로 액정(8)이 주입되어 있지 않은 실란트(6) 외측은 바깥쪽으로 휘려는 응력이 발생한다. 상기 상태가 복원되지 않고 계속 진행하게 되면 응력이 기판(2)(4)을 지지하는 실란트(6)의 지지력을 초과하게 되어 기판(2)(4)이 금가거나 깨지는 경우가 발생하게 되고 이로 인해 액정이 외부로 누출되게 된다.In the drawing, the portion where the liquid crystal 8 is injected with respect to the sealant 6 is bent at the center of the substrates 2, 4 and the polarizing plates 12, 14 and the liquid crystal 8 is not injected relatively. The sealant 6 outside the sealant 6 generates an outward stress. If the state continues without restoring the stress, the stress exceeds the holding force of the sealant 6 supporting the substrate 2, 4, which causes the substrate 2, 4 to crack or break. The liquid crystal leaks to the outside.
상기 액정표시소자를 어셈블리 후 기판(2)(4)과 편광판(12)(14)에 작용하는 응력을 측정한 결과 약 20∼30g에 달한다.After the assembly of the liquid crystal display device, the stresses applied to the substrates 2 and 4 and the polarizers 12 and 14 were measured to reach about 20 to 30 g.
글래스 기판으로 된 액정표시소자의 경우에는 글래스 자체의 지지력으로 응력의 영향을 심각하게 받지 않고 있으나 플라스틱 기판과 같이 플렉시블한 재료를 채용한 액정표시소자의 경우에는 빈번히 발생하고 있으면 현재까지 해결방안을 제시하지 못하는 문제점이 있다.In the case of liquid crystal display devices made of glass substrates, they are not severely affected by stress due to the supporting force of the glass itself. However, in the case of liquid crystal display devices employing flexible materials such as plastic substrates, if there are frequent occurrences, solutions have been proposed so far. There is a problem that can not be.
전술한 종래 기술의 문제점을 해결하기 위하여 안출된 본 발명은 플라스틱 기판을 실링하는 실란트 외곽으로 접착제인 에폭시를 도포하여 플라스티 기판을 고정해줌으로써 기판과 편광판의 휨 현상을 제거할 수 있는 플라스틱 액정표시소자를 제공함이 그 목적이다.The present invention has been made to solve the above-mentioned problems of the prior art is a plastic liquid crystal display that can remove the warp phenomenon of the substrate and the polarizing plate by fixing the plastic substrate by applying an epoxy epoxy adhesive to the sealant for sealing the plastic substrate It is an object to provide an element.
이를 위하여 바깥면에 편광판을 부착한 2매의 플라스틱 기판의 대향면에 투명 전극, 절연층 및 배향막을 형성하고 상기 기판사이를 1차적으로 실란트로 실링한 후 액정을 주입한 플라스틱 액정표시소자에 있어서, 상기 실란트 외곽으로 접착제인 에폭시를 도포하여 기판과 기판 사이의 외곽을 접착 지지함으로서 응력 발생에 대응하는 구성으로 이루어진다.In the plastic liquid crystal display device in which a transparent electrode, an insulating layer and an alignment layer are formed on opposite surfaces of two plastic substrates having a polarizing plate attached to the outer surface thereof, and the liquid crystal is injected after first sealing the substrates with a sealant. The adhesive is applied to the outside of the sealant to form an adhesive corresponding to the stress between the substrate and the substrate.
상기와 같은 구성으로 이루어진 플라스틱 액정표시소자는 실란트가 1차적으로 기판과 기판을 지지하고 외곽으로 접착제인 에폭시를 도포하여 접착력을 증가시켜 줌으로써, 열에 의한 휨을 방지하여 액정표시소자가 깨져 액정이 누출되지 않도록 하며 이로 인해 품질 신뢰성을 향상시킬 수 있다.The plastic liquid crystal display device having the above configuration increases the adhesive strength by first supporting the substrate and the substrate and applying epoxy as an adhesive to the outside to prevent the bending due to heat, thereby preventing the liquid crystal display device from being broken and causing the liquid crystal to leak. This can improve the quality reliability.

본 발명의 구성에 대하여 첨부한 도면에 의거하여 보다 상세히 설명한다. 참고로 본 발명의 구성요소 중 종래 도면과 일치하는 부분에 대해서는 종래 도면부호를 그대로 인용하기로 한다.EMBODIMENT OF THE INVENTION The structure of this invention is demonstrated in detail based on attached drawing. For reference, the same reference numerals are used as to the parts of the present invention that are identical to the conventional drawings.
도 1은 본 발명에 의한 플라스틱 액정표시소자를 분리하여 도시한 사시도이다.1 is a perspective view showing a separate plastic liquid crystal display device according to the present invention.
도면에서 보면, 중앙의 액정(8) 주입공간을 사이에 두고 상측과 하측에 기판(2)(4)이 위치하는 바, 상기 기판(2)(4)은 플라스틱 재질을 채용하여 상당히 플렉시블하다. 상기 기판(2)(4)에는 도시생략되었지만 기판과 기판의 대향면에 투명 전극이 패턴되고, 절연층과 배향막이 적층 형성되어 있다.As shown in the figure, the substrates 2 and 4 are located on the upper side and the lower side with the center of the liquid crystal 8 injection space interposed therebetween, and the substrates 2 and 4 adopt a plastic material and are quite flexible. Although not illustrated in the substrates 2 and 4, transparent electrodes are patterned on opposite sides of the substrate and the substrate, and an insulating layer and an alignment film are laminated.
상하측의 플라스틱 기판의 외측으로는 입사광에 방향성을 부여해 주는 편광판(12)(14)이 각각 부착되어 있다.On the outer side of the upper and lower plastic substrates, polarizing plates 12 and 14 which give directionality to incident light are respectively attached.
상측 기판(2)과 하측 기판(4)의 사이에는 액정(8)이 주입될 액정 주입구를 제외하고 실링을 하는 바 보통 에폭시 수지를 사용하여 실란트(6)를 프린트하게 된다. 위와 같이 실란트(6)로 실링을 한 외곽으로 공간이 남게 되는 데 이 공간에 도면에서 보는 바와 같이 접착제(20)를 도포하여 재차 실링을 하게 된다. 상기 접착제(20)는 보통 에폭시이다.Sealing is performed between the upper substrate 2 and the lower substrate 4 except for the liquid crystal injection hole through which the liquid crystal 8 is to be injected, so that the sealant 6 is usually printed using an epoxy resin. Space is left to the outside of the sealant with the sealant 6 as described above, and the sealant is applied again by applying the adhesive 20 as shown in the drawing. The adhesive 20 is usually epoxy.
접착제(20)로서 에폭시를 도포한 후 차후 공정을 거치고 주입구 를 통해 액정(8)을 주입한 후 엔드 실제(10)를 밀봉한 구성이다.After the epoxy is applied as the adhesive 20 through a subsequent process and the liquid crystal 8 is injected through the injection hole, the end seal 10 is sealed.
도 2에 본 발명에 의한 플라스틱 액정표시소자의 측단면을 개략적으로 도시한다.Figure 2 schematically shows a side cross-section of the plastic liquid crystal display device according to the present invention.
도면에서 보는 바와 같이 외측면에 편광판(12)(14)이 부착된 2매의 플라스틱 기판(2)(4)사이를 1 차적으로 실란트(6)로 접착하고 실란트(6) 외곽의 기판과 기판 사이에는 접착제(20)로 넓게 도포하여 접착지지력을 강화시킨다.As shown in the drawing, the two plastic substrates 2 and 4 with the polarizing plates 12 and 14 attached to the outer surface are first bonded with a sealant 6, and the substrate and the substrate outside the sealant 6 are It is widely applied with an adhesive 20 in between to strengthen the adhesive support.
종래와 같이 중앙부분에서 응력이 발생하더라도 실링부분이 넓게 지지하고있어 응력 발생량은 미미하게 된다.Even if stress occurs in the center portion as in the prior art, the sealing portion is widely supported, so the amount of stress generation is minimal.
상술한 구조로 본 발명이 이루어지면, 기판과 기판을 잡아주는 실란트 외에 접착제로서의 에폭시가 기판면에 부착됨으로서 기판면사이의 접착력을 향상시켜 기존과 같이 열처리가 끝난 후에도 플라스틱 기판과 편광판이 받는 응력을 지지해 줄 수 있고 인해 품질 신뢰성을 향상시킬 수 있다.When the present invention is made with the above-described structure, the epoxy as an adhesive is attached to the substrate surface in addition to the sealant for holding the substrate and the substrate, thereby improving the adhesive force between the substrate surfaces, so that the stress received by the plastic substrate and the polarizing plate even after the heat treatment is completed as before. Support and improve quality reliability.
상기와 같은 구성으로 이루어진 플라스틱 액정표시소자는 실란트가 1차적으로 기판과 기판을 지지하고 외곽으로 접착제인 에폭시를 도포하여 접착력을 증가시켜 줌으로써, 열에 의한 휨을 방지하여 액정표시소자가 깨져 액정이 누출되지 않도록 하며 이로 인해 품질 신뢰성을 향상시킬 수 있다.The plastic liquid crystal display device having the above configuration increases the adhesive strength by first supporting the substrate and the substrate and applying epoxy as an adhesive to the outside to prevent the bending due to heat, thereby preventing the liquid crystal display device from being broken and causing the liquid crystal to leak. This can improve the quality reliability.
