Description

액정표시소자LCD

본 발명은 액정표시소자(liquid crystal display:이하, LCD라 한다)에 관한 것으로, 보다 상세하게는 칼라필터의 픽셀 구조를 단순 변형하여 표시소자의 광시야각 특성을 개선시킬 수 있도록 한 액정표시소자에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device (hereinafter referred to as LCD). More particularly, the present invention relates to a liquid crystal display device in which a pixel structure of a color filter is simply modified to improve a wide viewing angle characteristic of the display device. It is about.

근래에 고품위 TV(high definition TV:HDTV) 등의 새로운 첨단 영상기기가 개발됨에 따라 평판표시기에 대한 요구가 대두되고 있다. LCD는 평판표시기의 대표적인 기술로써 ELD(electro luminescence display), VFD(vacuum fluorescence display), PDP(plasma display panel) 등이 해결하지 못한 칼라화, 저전력, 그리고 고속화등의 문제를 가지고 있지 않다. Recently, with the development of new high-tech video devices such as high definition TV (HDTV), the demand for flat panel displays is increasing. LCD is a representative technology of flat panel display, and it does not have problems such as colorization, low power, and high speed that ELD (electro luminescence display), VFD (vacuum fluorescence display), PDP (plasma display panel) cannot solve.

이 LCD는 크게 수동형과 능동형의 두가지 형태로 나누어지는데, 능동형 LCD는 각 화소 하나 하나를 박막트랜지스터(thin film transistor:이하, TFT라 한다)와 같은 능동소자가 제어하도록 되어 있어 응답속도, 시야각, 색재현성, 그리고 대조비(contrast ratio)에 있어서, 수동형 LCD보다 훨씬 뛰어나 100만 화소 이상의 해상도를 필요로 하는 HDTV에 가장 적합한 표시기로 사용되고 있다. 이에 따라, 박막트랜지스터의 중요성이 부각되면서 이에 대한 연구개발이 심화되고 있다. The LCD is divided into two types, passive and active. In the active LCD, each pixel is controlled by an active element such as a thin film transistor (hereinafter referred to as TFT), so that response speed, viewing angle, and color can be controlled. In terms of reproducibility and contrast ratio, they are much better than passive LCDs and are the most suitable indicators for HDTVs requiring resolutions of 1 million pixels or more. Accordingly, the importance of the thin film transistor is increasing, and the research and development thereof is intensifying.

상기 능동형 LCD의 특성을 평가하는 구성 요소 중 특히 시야각은 능동형 LCD의 가장 취약한 부분으로, 좌/우 또는 상/하로 시야각이 달라지게 되면 대조비가 저하되고 색 특성이 바뀌며 그레이 레벨(gray level)의 반전이 일어나는 등 여러 가지 특성 저하 현상이 나타나게 되어, 상기 능동형 LCD는 CRT(cathod ray tube)의 대체품으로 급속하게 급부상하고 있음에도 불구하고 시야각이 CRT에 비하여 대단히 작다는 단점을 극복하지 못하고 있다. Among the components for evaluating the characteristics of the active LCD, the viewing angle is the weakest part of the active LCD, and when the viewing angle is changed left / right or up / down, the contrast ratio decreases, the color characteristics change, and the gray level is reversed. Due to this phenomenon, various deterioration of the phenomenon occurs, and although the active LCD is rapidly emerging as an alternative to the cathode ray tube (CRT), the viewing angle is not very small compared to the CRT.

상기 능동형 LCD는 크게, 복수의 데이타 라인 및 게이트 라인이 서로 수직 교차되도록 배치되어, 그들의 교점에 각각 접속되도록 박막트랜지스터와 화소전극이 형성되고, 그 전면에 보호막(예컨대, 질화막)과 ITO 재질의 공통전극이 순차적으로 형성되어 있는 TFT 기판과, 블랙매트릭스와 칼라필터가 형성되고, 그 전면에 보호층 및 ITO 재질의 공통전극이 형성되어 있는 C/F 기판이 서로 마주보도록 배치되어, 그 사이의 수 μm 공간에 액정이 주입되는 구조로 이루어져 있다. 그리고, 상기 TFT 기판 및 C/F 기판의 공통전극 상부에는 표면이 러빙(rubbing)처리된 PI(polyimide) 재질의 배향막이 형성되어 있고, 상기 TFT 기판과 C/F 기판의 바깥쪽으로는 편광판이 부착되어 있다. In the active LCD, a plurality of data lines and gate lines are vertically intersected with each other, and a thin film transistor and a pixel electrode are formed so as to be connected to their intersections, and a protective film (for example, a nitride film) and an ITO material are common on the front surface. A TFT substrate having electrodes sequentially formed, a C / F substrate having a black matrix and a color filter formed thereon, and a protective layer and a common electrode of ITO formed on the front thereof are arranged to face each other. The liquid crystal is injected into the μm space. In addition, an alignment layer of PI (polyimide) material having a rubbing surface is formed on the common electrode of the TFT substrate and the C / F substrate, and a polarizer is attached to the outside of the TFT substrate and the C / F substrate. It is.

도 1에는 종래 일반적으로 이용되어 오던 LCD 패널 중 칼라필터 기판 측의 단위 픽셀 구조를 도시한 단면도가 제시되어 있다. 상기 단면도에서, 참조번호 10은 칼라필터 기판을, 참조번호 12는 블랙매트릭스를, 참조번호 14는 칼라필터를, 참조번호 16은 보호막을, 참조번호 18은 공통전극을, 참조번호 20은 편광판을 나타낸다. FIG. 1 is a cross-sectional view showing a unit pixel structure of a color filter substrate side among LCD panels which have been generally used. In the cross-sectional view, reference numeral 10 denotes a color filter substrate, reference numeral 12 denotes a black matrix, reference numeral 14 denotes a color filter, reference numeral 16 denotes a protective film, reference numeral 18 denotes a common electrode, and reference numeral 20 denotes a polarizing plate. Indicates.

상기와 같은 구조를 갖는 대화면 LCD는, 도 1에 제시된 단면도에서 알 수 있듯이 정면 시야각 방향으로 빛이 액정을 통과하는 경로 길이와, 사선 방향으로 빛이 액정을 통과하는 경로 길이 간에 큰 차이가 발생됨을 알 수 있다. In the large screen LCD having the above structure, as shown in the cross-sectional view of FIG. 1, a large difference occurs between a path length through which light passes through the liquid crystal in a front viewing angle direction and a path length through which light passes through a liquid crystal in an oblique direction. Able to know.

이러한 차이는 결국 빛이 액정 상에서 굴절하는 정도를 나타내는 " d * ㅿn(여기서, d는 액정의 셀 갭(cell gap)을 나타내고, ㅿn은 액정의 장축 방향과 단축 방향 간의 굴절률 차이를 나타낸다) 값"에 영향을 미쳐서 정면에서와 사선 방향에서의 광특성에 큰 차이를 야기시키게 될 뿐만 아니라 이러한 방식으로 액정을 통과한 빛이 칼라필터를 거쳐 편광판으로 투과될 경우, 상기 투과광이 칼라필터 주변부로 확산되지 못하므로 광시야각 특성이 저하되는 현상이 발생하여 픽셀 주변부의 화질이 떨어지게 되는 단점이 발생된다. This difference is in turn "d * ㅿ n, where d represents the cell gap of the liquid crystal and ㅿ n represents the difference in refractive index between the major and minor axes of the liquid crystal. Value ", which not only causes a large difference in optical characteristics in the front and oblique directions, but also when the light passing through the liquid crystal is transmitted through the color filter to the polarizer in this manner, the transmitted light is transmitted to the periphery of the color filter. Since it is not diffused, a phenomenon in which the wide viewing angle characteristic is deteriorated is generated, resulting in a deterioration in image quality of the pixel periphery.

따라서, 상기 능동형 LCD 구현시 보다 넓은 시야각을 확보하기 위하여 여러 가지 형태의 광시야각 기술들이 개발되고 있다. 그러나, 이러한 방법들은 모두 TFT의 복잡한 구조를 요구하거나, 복잡한 설계 사양 도입, 제조 공정 추가, 수율 감소 등의 문제점들을 안고 있어, 시야각 개선에 큰 도움을 주지 못하고 있는 실정이다. Accordingly, various types of wide viewing angle technologies have been developed to secure a wider viewing angle when the active LCD is implemented. However, all of these methods require complex structures of TFTs, introduce complex design specifications, add manufacturing processes, reduce yields, etc., and thus do not greatly improve the viewing angle.

이에 본 발명은 상기와 같은 문제점을 개선하기 위하여 이루어진 것으로, LCD 제조시 액정을 통과한 빛을 받아들이는 쪽의 칼라필터 구조를 오목렌즈 형상을 가지도록 형성시켜 주므로써, 다단계 공정추가 없이도 간단하게 시야각 특성을 개선할 수 있도록 한 액정표시소자를 제공함에 그 목적이 있다. Accordingly, the present invention has been made to improve the above problems, and by forming a color filter structure to receive the light passing through the liquid crystal to have a concave lens shape when manufacturing the LCD, a simple viewing angle without adding a multi-step process It is an object of the present invention to provide a liquid crystal display device capable of improving the characteristics.

상기와 같은 목적을 달성하기 위하여 본 발명에서는, 블랙 매트릭스와 칼라필터가 구비되어 있는 C/F 기판과, 복수의 데이타 라인과 게이트 라인이 격자상으로 배치되어 그들의 각 교점에 박막트랜지스터와 화소전극이 접속되어 있는 TFT 기판이 액정을 사이에 두고 조립되도록 이루어진 액정표시소자에 있어서, 상기 칼라필터의 일면이 오목렌즈 형상을 가지도록 제작된 것을 특징으로 하는 액정표시소자가 제공된다. In order to achieve the above object, in the present invention, a C / F substrate having a black matrix and a color filter, a plurality of data lines and a gate line are arranged in a lattice form, and thin film transistors and pixel electrodes are disposed at their intersections. A liquid crystal display device in which a connected TFT substrate is assembled with a liquid crystal interposed therebetween, wherein a liquid crystal display device is produced so that one surface of the color filter has a concave lens shape.

상기와 같이 LCD를 제조한 결과, 능동형 LCD의 시야각 특성을 개선할 수 있게 되어 액정표시소자의 화질을 개선할 수 있게 된다. As a result of manufacturing the LCD as described above, it is possible to improve the viewing angle characteristics of the active LCD can improve the image quality of the liquid crystal display device.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예에 대해 상세히 설명한다. Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

본 발명은 능동형 LCD 제조시, 칼라필터의 일면을 오목렌즈 형상을 가지도록 제작해주므로써, 다단계 공정 추가 없이도 광확산 원리를 이용하여 표시소자의 시야각 특성을 개선시킬 수 있도록 하는데 주안점을 둔 기술로서, 이를 보다 구체적으로 살펴보면 다음과 같다. The present invention is a technology that focuses on improving the viewing angle characteristics of the display device by using the light diffusion principle without the addition of a multi-step process by manufacturing one surface of the color filter to have a concave lens shape in the active LCD manufacturing, Looking at this in more detail as follows.

도 2에는 본 발명에 의해 제조된 LCD 패널의 C/F 기판 측의 단위 픽셀 구조를 도시한 단면도가 제시되어 있다. 본 발명의 경우, TFT 기판은 종래와 동일한 구조를 가지도록 제작되므로, 본 발명에 의해 제조되는 액정표시소자는 다음과 같은 구조를 갖는다. 2 is a cross-sectional view showing the unit pixel structure on the C / F substrate side of the LCD panel manufactured by the present invention. In the case of the present invention, since the TFT substrate is manufactured to have the same structure as the conventional one, the liquid crystal display device manufactured by the present invention has the following structure.

즉, 본 발명에 의해 제조된 대화면 LCD는 크게, 복수의 데이타 라인 및 게이트 라인이 서로 수직 교차되도록 배치되어, 그들의 교점에 각각 접속되도록 박막트랜지스터와 화소전극이 형성되고, 그 전면에 보호막(예컨대, 질화막)과 ITO 재질의 공통전극이 순차적으로 형성되어 있는 TFT 기판(미 도시)과, 블랙매트릭스(102)와 일면이 오목렌즈 형상을 갖는 구조의 칼라필터(103)가 형성되고, 그 전면에 보호막(104)과 ITO 재질의 공통전극(106)이 형성되어 있는 C/F 기판(100)이 서로 마주보도록 배치되어, 그 사이의 수 μm 공간에 액정(112)이 주입되며, C/F 기판(100)의 외측에 편광판(108)이 배치되는 구조로 이루어져 있음을 알 수 있다. That is, the large screen LCD manufactured by the present invention is largely arranged such that a plurality of data lines and gate lines vertically intersect with each other, and a thin film transistor and a pixel electrode are formed so as to be connected to their intersections, respectively, and a protective film (eg, A TFT substrate (not shown) in which a nitride film) and a common electrode made of ITO are sequentially formed, and a color filter 103 having a concave lens shape on one surface of the black matrix 102 is formed, and a protective film on the entire surface thereof. The C / F substrate 100 on which the 104 and the ITO common electrode 106 are formed is disposed to face each other, and the liquid crystal 112 is injected into a space of several μm therebetween, and the C / F substrate ( It can be seen that the polarizing plate 108 is disposed outside the 100.

이때, 상기 칼라필터(103)는 상기 도면에서 알 수 있듯이 액정(112)을 통과한 빛을 받아들이는 쪽의 면이 오목렌즈 형상을 가지도록 제작된다. In this case, as shown in the drawing, the color filter 103 is manufactured to have a concave lens shape on the side of the light receiving light passing through the liquid crystal 112.

이와 같이 칼라필터(103)를 제조할 경우, 한 픽셀(pixel) 내에서 칼라필터(103)가 중심과 모서리 부분에서 서로 이원화된 두께를 가지게 되어, 픽셀 에지부에서의 셀 갭이 픽셀 중심부에서의 셀 갭보다 작도록 LCD를 구현할 수 있을 뿐 아니라 상기 칼라필터(103)의 구조가 오목렌즈 형상을 가지므로 광확산 원리에 의해 도시된 바와 같이 광(110)을 확산시킬 수 있음을 알 수 있다. When the color filter 103 is manufactured as described above, the color filter 103 has a thickness dualized at the center and the corner portion within one pixel, so that the cell gap at the pixel edge portion is It can be seen that not only the LCD can be implemented to be smaller than the cell gap but also the color filter 103 has a concave lens shape, so that the light 110 can be diffused as shown by the light diffusion principle.

상기 단면도를 참조하면, 도 1에 제시된 기존의 LCD 픽셀 구조와 비교할 때, 각각의 포인트 및 방향에서의 빛의 사선 방향으로의 경로 길이가 모두 줄어듦을 알 수 있다. 이로 인해, 정면 방향에서 높던 대조비가 시야각이 바뀌면서 급격하게 낮아지는 현상을 개선할 수 있을 뿐 아니라 광확산을 통해 시야각 특성을 개선할 수 있게 된다.Referring to the cross-sectional view, it can be seen that when compared with the conventional LCD pixel structure shown in FIG. 1, all path lengths in the diagonal direction of light at each point and direction are reduced. As a result, not only the contrast ratio, which is high in the front direction, is sharply lowered as the viewing angle is changed, but also the viewing angle characteristic can be improved through light diffusion.

상술한 바와 같이 본 발명에 의하면, 능동형 LCD 제조시 칼라필터의 형상을 일면이 오목렌즈 구조를 가지도록 제작해주므로써, 다단계 공정추가 없이도 시야각 특성 및 색재현성 특성을 개선할 수 있게 된다.As described above, according to the present invention, since the shape of the color filter is manufactured to have a concave lens structure when the active LCD is manufactured, the viewing angle characteristic and the color reproducibility characteristic can be improved without the addition of a multi-step process.
