Description
본 발명은 액정표시소자(liquid crystal display)에 관한 것으로서, 특히 광위상차판을 기판으로 직접 사용함으로써 소자의 구조를 단순화하고, 제작비용을 감축할 수 있는 액정표시소자에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display, and more particularly, to a liquid crystal display capable of simplifying the structure of a device and reducing manufacturing costs by directly using an optical phase difference plate as a substrate.
액정표시소자는 액체와 고체의 중간 상태인 액정(liquid crystal)이라는 물질을 이용하여 전압과 온도의 변화에 따라 빛을 투과 또는 차단시켜 명암을 제어함으로써 원하는 형상을 표시하는 장치이다. 이와 같은 액정표시소자는 저소비전력, 박형 및 소형화의 장점이 있어 널리 사용되고 있으나, 대형화, 완전 칼라 실현, 시야각 확대 등의 해결과제를 안고 있다.A liquid crystal display device is a device that displays a desired shape by controlling the contrast by transmitting or blocking light according to a change in voltage and temperature using a material called liquid crystal which is an intermediate state between a liquid and a solid. Such liquid crystal display devices have been widely used because of their low power consumption, thinness, and miniaturization, but have problems such as large size, full color, and wide viewing angle.
한편, 이와 같은 액정표시소자는 그 동작 모드, 예컨대 DS(Dynamic Scattering) 모드, GH(Guest Host) 모드, TN(Twisted Nematic) 모드, STN(Super Twisted Nematic) 모드 등에 따라 여러 가지로 분류된다. 여기서, 각 동작 모드에 대해 간략히 설명해 보면 다음과 같다.Such liquid crystal display devices are classified into various types according to their operation modes, for example, a dynamic scattering (DS) mode, a guest host (GH) mode, a twisted nematic (TN) mode, a super twisted nematic (STN) mode, and the like. Here, a brief description of each operation mode is as follows.
DS 모드는 액정의 전기광학 효과를 이용한 것으로서, 편광판이 불필요하고 시각 의존성이 적다는 장점이 있지만 소비전력이 크고 특히 반사형은 표시면이 거울면이기 때문에 보기어렵다는 결점이 있다. GH 모드는 액정에 첨가한 2색성 색소의 광흡수 계수의 이방성을 이용한 것으로서, 칼라 스위칭이 가능하고 넓은 시야각 및 저전압 구동 등의 장점이 있다. TN 모드는 투명 전극을 도포한 2매의 유리기판 사이에 정(正)의 유전율 이방성 네마틱 액정의 박층을 끼워 액정 분자의 장축이 유리기판면에 평행으로, 상하 기판 사이에서 연속적으로 90°비틀어진 배열을 갖게 한 것으로서, 저전압구동, 저소비전력, 긴 수명 등의 장점이 있지만, 시야각이 한정되는 단점이 있다. STN 모드는 상기 TN 모드에서 액정 분자의 비틀림 각을 더욱 크게 한 것으로서, 멀티플렉스 구동 및 고화질을 얻을 수 있는 장점이 있지만, 복굴절 효과로 비선택 상태가 착색되므로 멀티컬러화가 곤란하다는 단점이 있다.DS mode uses the electro-optic effect of the liquid crystal, which has the advantage that the polarizing plate is unnecessary and the visual dependence is small, but the drawback is that it is difficult to see because the power consumption is large and the reflective type is the mirror surface. The GH mode uses anisotropy of the light absorption coefficient of the dichroic dye added to the liquid crystal, and has advantages such as color switching, wide viewing angle, and low voltage driving. In the TN mode, a thin layer of positive dielectric anisotropic nematic liquid crystal is sandwiched between two glass substrates coated with a transparent electrode, and the long axis of the liquid crystal molecules is twisted by 90 ° continuously between the upper and lower substrates in parallel to the glass substrate surface. As a result of having a true arrangement, there are advantages such as low voltage driving, low power consumption, and long life, but there is a disadvantage in that the viewing angle is limited. In the STN mode, the torsion angle of the liquid crystal molecules is further increased in the TN mode, and there is an advantage in that multiplex driving and high image quality can be obtained.
도 1은 종래 STN 모드 액정표시소자의 구성을 개략적으로 나타내 보인 수직단면도이다.1 is a vertical sectional view schematically showing the configuration of a conventional STN mode liquid crystal display device.
도 1을 참조하면, 종래 STN 모드 액정표시소자는 그 중심부에 액정(11)이 채워져 있고,(여기서, 본 도면에는 도시되지 않았지만 적층 구조체의 전,후,좌,우 측면부에는 씰링부재가 마련되어 상,하부의 부재와 함께 밀폐된 용기를 구성한다. 따라서, 액정이 채워질 수 있다.) 액정(11)의 상,하면에는 액정(11)의 배향을 유도하는 상,하부 배향막(12a)(12b)이 마련되어 있다. 또한, 그 상,하부 배향막(12a) (12b)의 외면에는 상기 액정(11)에 전류를 공급하기 위한 ITO(Indium Tin Oxide) 전극(13a)(13b)이 각각 마련되어 있고, 그 전극(13a)(13b)의 외측으로는 유리 혹은 플라스틱 재질의 기판(14a)(14b)이 설치되어 있다. 그리고, 그 기판(14a)(14b)의 외측으로는 기판과 소정 간격 이격되어 광위상차판(retardation film)(15a)(15b)이 각각 마련되어 있고, 그 광위상차판(15a)(15b)과 다시 각각 소정 간격 이격되어 편광판(16a)(16b)이 마련되어 있다. 그리고, 일측 편광판(16b)의 하부에는 반사판(17)이 마련되어 있다.Referring to FIG. 1, in the conventional STN mode liquid crystal display device, the liquid crystal 11 is filled in the center thereof (not shown in this drawing, but sealing members are provided on the front, rear, left, and right side portions of the laminated structure. The upper and lower alignment layers 12a and 12b which induce the alignment of the liquid crystal 11 are formed on the upper and lower surfaces of the liquid crystal 11. This is provided. Further, indium tin oxide (ITO) electrodes 13a and 13b for supplying current to the liquid crystal 11 are provided on the outer surfaces of the upper and lower alignment layers 12a and 12b, respectively. Outside of 13b, board | substrates 14a and 14b of glass or plastic material are provided. On the outside of the substrates 14a and 14b, photoretardation films 15a and 15b are provided to be spaced apart from the substrate by a predetermined distance, and the optical phase difference plates 15a and 15b are provided again. The polarizing plates 16a and 16b are provided spaced apart by predetermined intervals, respectively. And the reflecting plate 17 is provided in the lower part of the one side polarizing plate 16b.
이상과 같은 구성을 가지는 종래 STN 모드 액정표시소자에 있어서, 플렉시블한 액정표시소자를 만들기 위하여 통상 유리기판을 플라스틱 기판으로 대체하고 있다. 그런데, 이 경우 상기 편광판(16a)(16b) 사이에 복굴절 이방성이 있는 플라스틱 기판이 들어가면, 상기 편광판(16a)(16b)과의 상호 작용에 의해 또 다른 광위상차 효과를 나타내어 형상의 표시가 어려워진다. 따라서, 복굴절 이방성이 없는 플라스틱 기판을 사용해야 하는데, 그에 따라 플라스틱 기판의 제조법이 다르게 되고, 그것은 궁극적으로 액정표시소자의 제작비용을 상승시킨다.In the conventional STN mode liquid crystal display device having the above configuration, in order to make a flexible liquid crystal display device, a glass substrate is usually replaced by a plastic substrate. In this case, however, when a plastic substrate having birefringence anisotropy enters between the polarizing plates 16a and 16b, the optical display becomes difficult due to interaction with the polarizing plates 16a and 16b, thereby making it difficult to display the shape. . Therefore, a plastic substrate having no birefringence anisotropy should be used, and accordingly, the manufacturing method of the plastic substrate is different, which ultimately increases the manufacturing cost of the liquid crystal display device.
본 발명은 상기와 같은 문제점을 감안하여 창출된 것으로서, 플렉시블한 기판의 역할을 광위상차판이 대신하게 함으로써 소자의 구조 및 제작공정을 단순화하고 소자의 전체적인 제작비용을 감축할 수 있는 액정표시소자를 제공함에 그 목적이 있다.The present invention has been made in view of the above problems, and by providing an optical phase plate to replace the role of a flexible substrate, it provides a liquid crystal display device that can simplify the structure and manufacturing process of the device and reduce the overall manufacturing cost of the device. Has its purpose.

이하 도면을 참조하면서 본 발명의 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명에 따른 액정표시소자의 구성을 개략적으로 나타내 보인 수직단면도이다.2 is a vertical sectional view schematically showing the configuration of a liquid crystal display device according to the present invention.
도 2를 참조하면, 본 발명의 액정표시소자는 그 중심부에 액정(21)이 채워지고, 그 액정(21)의 상,하면에는 액정(21)의 배향을 유도하는 상,하부 배향막(22a) (22b)이 마련된다. 또한, 그 상,하부 배향막(22a)(22b)의 상부 및 하부에는 상기 액정(21)에 전류를 공급하기 위한 상,하부 ITO 전극(24a)(24b)이 각각 마련되고, 그 전극(24a)(24b)의 상부 및 하부에는 광위상차판(26a)(26b)이 각각 마련된다.Referring to FIG. 2, in the liquid crystal display device of the present invention, the liquid crystal 21 is filled in the center thereof, and the upper and lower alignment layers 22a inducing the alignment of the liquid crystal 21 on the upper and lower surfaces of the liquid crystal 21. 22b is provided.
