본 고안은 액정표시장치에 관한 것으로서, 더 상세하게는 칼라 표시화가 가능한 액정표시장치에 관한 것이다.The present invention relates to a liquid crystal display device, and more particularly to a liquid crystal display device capable of color display.
통상적으로 액정표시장치는 음극선관 발광다이오드 형광표시관 등과 같이 스스로 발광하는 소자가 아니고 인쇄물과 같이 외부로부터 빛을 받아서 눈에 보이게 되는 수광형 소자인데, 이와같은 액정표시장치에 의해 표시되는 문자 또는 도형을 칼라표시화하기 위해서 전면패널과 편광판 사이에 컬러 필터층을 개재시켜 왔다.In general, a liquid crystal display device is not a device that emits light by itself, such as a cathode ray tube light emitting diode fluorescent display tube, but a light receiving type device that receives light from the outside, such as printed matter, and is visible. In order to color display the color filter layer has been interposed between the front panel and the polarizing plate.
제1도에는 이러한 액정표시장치의 일예를 나타내 보였다.1 shows an example of such a liquid crystal display.
이것은 전면패널(2)과 배면패널(3)의 상호 대향되는 각면에 소정의 전극패턴(2a)(3a)과, 액정분자를 소정의 방향으로 배향시키는 배향막(2b)(3b)이 순차적으로 적층되고, 상기 전면패널(2)과 배면패널(3)은 그 가장자리에 설치되는 측면글래스(4)에 의해 접합되어 액정이 주입되는 소정의 폐쇄공간(4a)이 형성된다. 그리고 상기 전면패널(2)과 배면패널(3)의 각 외측면에는 편광판(5)(5′)이 설치되는데, 상기 전면패널(2)과 편광판(5)사이에는 소정색의 칼라 필터층(6)이 형성된다.This is because a predetermined electrode pattern (2a) (3a) and alignment films (2b) (3b) for aligning liquid crystal molecules in a predetermined direction are sequentially stacked on respective surfaces of the front panel (2) and the rear panel (3) facing each other. The front panel 2 and the rear panel 3 are joined by side glass 4 provided at their edges to form a predetermined closed space 4a into which liquid crystal is injected. In addition, polarizing plates 5 and 5 'are provided on each of the outer surfaces of the front panel 2 and the rear panel 3, and a color filter layer 6 having a predetermined color is disposed between the front panel 2 and the polarizing plate 5. ) Is formed.
이와같이 구성된 종래의 액정표시장치(1)는 상기 전극패턴(2a)(3a)에 소정의 전압을 인가함으로써 상기 액정이 소정의 방향으로 배향되어 전계가 인가된 부분이 밝게 보이는데, 상기 전면패널(2)의 상면에 소정색깔의 칼라 필터층(6)이 마련되어 있으므로 상기 액정표시장치(1)에 의해 표시되는 문자 또는 도형을 소망하는 색깔로 칼라화 할 수 있다. 그런데, 상기 칼라 필터층(6)은 상기 전면패널(2)과 편광판(5)사이에 소정의 칼라잉크를 인쇄하여 원하는 색을 나타낼 수 있도록 된 것이므로 한가지의 색으로 밖에 표현한 수 없었다. 따라서 액정표시장치에 의해 표쇠된 문자 또는 도형의 색을 다양화 할 수 없는 문제점이 있었다.In the conventional liquid crystal display device 1 configured as described above, by applying a predetermined voltage to the electrode patterns 2a and 3a, the liquid crystal is oriented in a predetermined direction so that a portion to which an electric field is applied appears bright. Since a color filter layer 6 of a predetermined color is provided on the upper surface of the N-axis, characters or graphics displayed by the liquid crystal display device 1 can be colored into a desired color. By the way, the color filter layer 6 can express a desired color by printing a predetermined color ink between the front panel 2 and the polarizing plate 5, so it can only be expressed in one color. Therefore, there is a problem in that the color of the letters or figures displayed by the liquid crystal display cannot be diversified.
본 고안은 상기 문제점을 해결하기 위하여 창출된 것으로서, 표시되는 문자 또는 도형의 색을 단색이 아닌 다색으로 표시할 수 있어 그 칼라특성을 대폭 향샹시킬 수 있는 액정표시장치를 제공함에 그 목적이 있다.The present invention was created to solve the above problems, and an object of the present invention is to provide a liquid crystal display device that can display a color of a displayed character or figure in a multicolored color instead of a single color, thereby greatly improving its color characteristics.
상기 목적을 달성하기 위하여 본 고안은 상호 대향되는 면에 소정패턴의 전극과 배향막이 적층된 전면패널 및 배면패널과, 상기 전면패널과 배면패널을 상호 접합하여 액정이 주입되는 폐쇄공간을 형성하는 실링재를 구비하여 된 액정표시장치에 있어서, 상기 전극이 복수개의 분할전극으로 분할되어 이 각각 전원과 연결되도록 되며 상기 분할전극의 상면에는 설 다른 색의 칼라필터층을 형성되어 된 것을 그 특징으로 한다.In order to achieve the above object, the present invention provides a sealing material for forming a closed space into which a liquid crystal is injected by mutually bonding the front panel and the rear panel, and the front panel and the rear panel, in which electrodes and an alignment layer of a predetermined pattern are stacked on opposite surfaces. In the liquid crystal display device provided with a plurality of split electrodes, the electrodes are divided into a plurality of split electrodes so as to be connected to a power source, and a color filter layer having a different color is formed on an upper surface of the split electrodes.
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 액정표시장치(10)가 도시되어 있는 바, 이는 상호 대향되는 각 면에 소정의 패턴으로 형성된 전극(20)(12a)과, 배향막(11b)(12b)이 적층된 전면패널(11)과 배면패널(12)은 그 가장자리에 위치되는 실링부재 즉, 측면글래스(13)에 의해 접합되어 액정이 주입되는 소정의 폐쇄공간(14)을 형성하게 된다. 그리고, 전면패널(11)과 배면패널(12)의 외측에는 편광판(15)(15′)이 설치된다. 여기에서 상기 전면패널(11)에 형성된 소정패턴의 전극(20)은 본 고안의 특징에 따라 제2b도에 나타내 보인 바와같이 미세하게 복수개의 분할전극(21)(22)으로 분할되고 이 분할전극(21)(22)은 각각 전원과 연결되며 그 상면에는 서로 다른 색깔의 칼라 필터층(23)이 형성된다. 이때에 상기 각 분할전극(21)(22)은 상호 접촉되지 않고 엇갈리도록 하여 하나의 전극패턴 전영역에 위치되도록 함이 바람직하다.FIG. 2 shows a liquid crystal display device 10 according to the present invention, in which electrodes 20 and 12a and alignment films 11b and 12b formed in a predetermined pattern are formed on respective surfaces facing each other. The front panel 11 and the rear panel 12 are joined by a sealing member located at the edge thereof, that is, the side glass 13 to form a predetermined closed space 14 into which the liquid crystal is injected. The polarizers 15 and 15 'are provided outside the front panel 11 and the rear panel 12, respectively. Here, the electrode 20 having a predetermined pattern formed on the front panel 11 is finely divided into a plurality of split electrodes 21 and 22 as shown in FIG. 2B according to the characteristics of the present invention. 21 and 22 are respectively connected to a power source, and color filter layers 23 of different colors are formed on the upper surface thereof. At this time, it is preferable that the divided electrodes 21 and 22 are located in the entire area of one electrode pattern by being staggered without being in contact with each other.
이와같이 구성된 본 고안에 따른 액정표시장치(10)는 상기 전극(20)(12a)에 소정의 전압을 인가하여 액정의 소정영역에 전계를 부여하게 되면 그 영역에서의 액정분자는 소정의 방향으로 배향된다. 따라서 액정의 전계가 인가되지 않은 부분은 어둡게 되고 전계가 인가된 부분은 밝게 보인다. 그런데, 상기 전면패널(11)에 형성된 전극(20)은 복수개의 분할전극(21)(22)으로 분할되고 각 분할전극(21)(22)에는 각각 전원과 연결되고 그 상면에는 서로 다른 색깔의 칼라 필터층(23)이 형성되어 있으므로 소망하는 문자 및 도형을 복수의 색으로 나타낼 수 있다. 즉, 상기 분할전극(21)(22)에는 각각의 전원이 인가되어 있으므로 소망하는 색깔의 칼라필터층(23)이 그 상면에 형성된 분할전극(21)(22)에 선택적으로 전원을 인가함으로써 소망하는 색깔로 도형 및 문자를 나타낼 수 있게 되는 것이다.In the liquid crystal display device 10 according to the present invention configured as described above, when a predetermined voltage is applied to the electrodes 20 and 12a to impart an electric field to a predetermined region of the liquid crystal, the liquid crystal molecules in the region are aligned in a predetermined direction. do. Therefore, the part where the electric field of the liquid crystal is not applied becomes dark and the part where the electric field is applied appears bright. By the way, the electrode 20 formed on the front panel 11 is divided into a plurality of split electrodes 21 and 22 and connected to a power supply to each of the split electrodes 21 and 22, respectively, and have different colors on the upper surface thereof. Since the color filter layer 23 is formed, desired characters and figures can be represented by a plurality of colors. That is, since the respective powers are applied to the split electrodes 21 and 22, the color filter layer 23 of the desired color is selectively applied by selectively applying power to the split electrodes 21 and 22 formed on the upper surface thereof. Colors can be used to represent figures and characters.
이와같이 본 고안 액정표시장치는 소정패턴의 전극이 복수개의 분할전극으로 분할되고 그 상면에 서로 다른 칼라 필터층이 형성됨으로써 소망하는 문자 및 도형을 여러가지의 색깔로 표현이 가능하게 된다. 또한 본 고안은 상기 분할전극의 상면에 형성하게 되므로 종래에 비해 해상도를 향상시킬 수 있으며 나아가서는 제품의 상품적 가치를 향상시킬 수 있는 이점이 있다.As described above, in the liquid crystal display device of the present invention, the electrode having a predetermined pattern is divided into a plurality of split electrodes, and different color filter layers are formed on the upper surface thereof, so that desired characters and figures can be expressed in various colors. In addition, since the present invention is formed on the upper surface of the split electrode, the resolution can be improved as compared with the related art, and furthermore, the merchandise value of the product can be improved.
