Description
본 발명은 액정표시장치에 관한 것으로서, 보다 구체적으로는, 지주형 스페이서의 형성 위치를 변경하여 균일한 셀 갭(cell gap) 유지가 가능하도록 한 지주형 스페이서를 갖는 액정표시장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device having a columnar spacer capable of maintaining a uniform cell gap by changing a formation position of the columnar spacers.
액정표시장치는 투명 전극이 형성된 두장의 기판 사이에 수 개의 액정 분자들로 구성된 액정층을 개재시킨 후, 상기 투명 전극들 사이에서 일어나는 전계에 의하여 액정 분자들의 배열을 변화시켜 빛의 투과량이 제어되도록 하는 것에 의해 소정의 화상을 표시하는 장치이다.The liquid crystal display device interposes a liquid crystal layer composed of several liquid crystal molecules between two substrates on which transparent electrodes are formed, and then changes the arrangement of liquid crystal molecules by an electric field generated between the transparent electrodes to control the amount of light transmitted. It is an apparatus which displays a predetermined image by doing.
이러한 액정표시장치에 있어서, 응답속도, 대비비, 시야각, 휘도 균일성 등의 특성은 액정층의 두께, 즉, 셀 갭(cell gap)과 밀접한 관련을 갖기 때문에, 액정표시장치의 화면품위를 향상시키기 위해서는 균일한 셀 갭을 유지시키는 것이 매우 중요하다. 특히, 액정표시장치가 대면적화 및 고품질화 되어가는 추세에서, 일정한 셀 갭의 유지는 더욱 중요시되고 있다.In such a liquid crystal display device, characteristics such as response speed, contrast ratio, viewing angle, and luminance uniformity are closely related to the thickness of the liquid crystal layer, that is, the cell gap, thereby improving the screen quality of the liquid crystal display device. In order to achieve this, it is very important to maintain a uniform cell gap. In particular, in the trend toward larger areas and higher quality of liquid crystal displays, maintaining a constant cell gap is becoming more important.
따라서, 현재 대부분의 액정표시장치는 그 제조 과정에서, 예컨데, 기판들간의 합착 과정에서 어느 하나의 기판 상에 셀 갭(cell gap) 유지용 스페이서를 산포하고 있다.Therefore, at present, most liquid crystal display devices distribute cell gap holding spacers on any one substrate in a manufacturing process thereof, for example, in a bonding process between the substrates.
그런데, 이러한 스페이서 산포 방식에 있어서는 스페이서의 균일한 산포가 어렵고, 스페이서의 뭉침 현상이 발생되며, 또한, 스페이서 주변에서 빛샘이 발생하여, 균일한 셀 갭 유지가 어려움은 물론 화질 저하의 결과가 초래되기도 한다.However, in such a spacer spreading method, it is difficult to uniformly distribute the spacers, agglomeration of the spacers occurs, and light leakage occurs around the spacers, which makes it difficult to maintain a uniform cell gap and may result in deterioration of image quality. do.
이에, 셀 갭 유지를 위한 종래의 다른 방법으로서, 컬러필터 기판에 지주형 스페이서를 형성하는 방법이 제안되었다.Accordingly, as another conventional method for maintaining a cell gap, a method of forming a strut spacer on a color filter substrate has been proposed.
상기 지주형 스페이서는 컬러필터 기판에 구비되는 블랙 매트릭스 상부의 특정 부분, 보다 자세하게, 구동 모드로서 수직 전계를 이용하는 액정표시장치에서의 컬러필터 기판의 경우에는 블랙 매트릭스 상에 형성되는 상대전극 물질인 ITO층 상에, 그리고, 수평 전계를 이용한 액정표시장치에서의 컬러필터 기판의 경우에는 블랙 매트릭스 상에 형성되는 오버코트층 상에 포토레지스트의 도포, 노광 및 현상을 통해 형성된다.The holding spacer is a counterpart material formed on the black matrix in the case of a color filter substrate in a liquid crystal display device using a vertical electric field as a driving mode. In the case of a color filter substrate in a liquid crystal display device using a horizontal electric field, on a layer, and on an overcoat layer formed on a black matrix, the photoresist is formed through application, exposure and development.
도 1은 종래의 지주형 스페이서가 구비된 컬러필터 기판의 평면도로서, 여기서, 도면부호 2는 블랙 매트릭스를, 4는 컬러필터를, 6은 지주형 스페이서를, 그리고, 10은 컬러필터 기판을 각각 나타낸다.1 is a plan view of a conventional color filter substrate having a post spacer, where 2 is a black matrix, 4 is a color filter, 6 is a post spacer, and 10 is a color filter substrate, respectively. Indicates.
도시된 바와 같이, 블랙 매트릭스(2)에 의해 한정된 각 화소의 대응 영역에는 레드, 그린 및 블루로 구성된 삼색의 컬러필터(4)가 형성되어 있고, 상기 블랙 매트릭스(2)의 특정 부분 상에는 포토레지스트의 도포, 노광 및 현상을 통해 도트형으로된 지주형 스페이서(6)가 형성되어 있다.As shown, a three-color color filter 4 composed of red, green and blue is formed in a corresponding region of each pixel defined by the black matrix 2, and a photoresist is formed on a specific portion of the black matrix 2. Through the application, exposure and development of the pillar-shaped spacers 6 in the form of dots are formed.
그러나, 전술한 바와 같은 종래의 액정표시장치는 도트형으로된 지주형 스페이서들간의 간격이 너무 멀고, 특히, 그 크기가 작은 것과 관련하여, 파손이나 결함이 발생되기 쉬우며, 이에 따라, 패널의 전 영역에 대해 균일한 셀 갭 유지가 이루어지지 않음으로써, 패널 상에 얼룩이 발생되는 등의 액정표시장치의 화면품위 저하가 초래되는 문제점이 있다.However, the above-described conventional liquid crystal display device is too far apart between the dot-shaped strut spacers, and particularly, in relation to the small size thereof, breakage or defects are likely to occur, and therefore, Since the cell gap is not maintained uniformly over the entire area, there is a problem in that the screen quality of the liquid crystal display device such as unevenness is generated on the panel.
따라서, 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 패널 상의 전 영역에 대해 균일한 셀 갭 유지가 가능하도록 한 액정표시장치를 제공함에 그 목적이 있다.Accordingly, an object of the present invention is to provide a liquid crystal display device capable of maintaining a uniform cell gap for all areas on a panel.

본 발명에 따르면, 지주형 스페이서를 블랙 매트릭스 상의 전 영역, 또는, 일 방향으로만 라인 형태로 형성함으로써, 그 유실 및 파손을 방지할 수 있으며, 이에 따라, 균일한 셀 갭 유지가 가능하여 액정표시장치의 화면품위 저하를 방지할 수 있다.According to the present invention, the holding spacers can be formed in the form of lines in the entire area on the black matrix or only in one direction, thereby preventing the loss and damage thereof, thereby maintaining a uniform cell gap, thereby providing a liquid crystal display. The deterioration of the screen quality of the device can be prevented.
(실시예)(Example)
이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 보다 상세하게 설명하도록 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
먼저, 본 발명의 액정표시장치는 매트릭스 형태로 구획된 각 화소마다 박막 트랜지스터 및 화소전극이 구비된 어레이 기판과, 상기 화소전극에 대응해서 컬러필터가 형성되면서 각 화소의 경계부에 대응해서 블랙 매트릭스가 형성된 컬러필터 기판이 수 개의 액정분자들로 구성된 액정층의 개재하에 합착된 구조를 이룬다.First, the liquid crystal display of the present invention includes an array substrate including a thin film transistor and a pixel electrode for each pixel partitioned in a matrix form, and a black matrix corresponding to the boundary of each pixel while a color filter is formed corresponding to the pixel electrode. The formed color filter substrate forms a bonded structure under the interposition of the liquid crystal layer composed of several liquid crystal molecules.
여기서, 상기 컬러필터 기판의 블랙 매트릭스 상에 형성된 ITO 또는 오버코팅층 상에는 기판들간의 간격 유지를 위한 스페이서가 포토레지스트의 도포, 노광 및 현상을 통해 지주형으로 구비되며, 이때, 상기 지주형 스페이서는 종래의 도트형이 아닌, 블랙 매트릭스의 전 영역 상에 라인 형태로 구비된다.Here, on the ITO or overcoating layer formed on the black matrix of the color filter substrate, a spacer for maintaining a gap between the substrates is provided in a post form by applying, exposing and developing photoresist, wherein the post spacer is Is provided in the form of lines on the entire area of the black matrix, not in the dot form.
자세하게, 도 2는 본 발명의 실시예에 따른 지주형 스페이서가 구비된 컬러필터 기판을 도시한 평면도로서, 도시된 바와 같이, 본 발명의 지주형 스페이서(8)는 블랙 매트릭스(도시안됨)의 전 영역 상에, 종래의 도트형이 아닌, 라인 형태로 형성된다. 이때, 상기 지주형 스페이서(8)는 2∼10㎛의 높이 및 3∼30㎛ 폭으로 형성된다.In detail, Fig. 2 is a plan view showing a color filter substrate having a post spacer according to an embodiment of the present invention, and as shown, the post spacer 8 of the present invention is formed by the front of the black matrix (not shown). On the region, it is formed in the form of a line rather than the conventional dot. At this time, the post spacer 8 is formed to have a height of 2 to 10 µm and a width of 3 to 30 µm.
도 2에서, 미설명된 도면부호 4는 컬러필터를, 그리고, 10은 컬러필터 기판을 각각 나타낸다.In FIG. 2, reference numeral 4 denotes a color filter, and 10 denotes a color filter substrate.
또한, 전술한 바와 같이, 지주형 스페이서를 컬러필터 기판의 블랙 매트릭스의 전 영역 상에 구비시킬 경우, 어레이 기판 표면의 단차로 인해 정확한 셀 갭 유지에 어려움이 있을 수 있다.In addition, as described above, when the post spacer is disposed on the entire region of the black matrix of the color filter substrate, it may be difficult to maintain the accurate cell gap due to the step difference of the surface of the array substrate.
따라서, 본 발명의 실시예에서는 어레이 기판의 최상부에 오버코트층을 도포하여 어레이 기판을 어느 정도 평탄화시킨다.Therefore, in the embodiment of the present invention, the overcoat layer is applied to the top of the array substrate to planarize the array substrate to some extent.
이와 같은 본 발명의 액정표시장치에 따르면, 지주형 스페이서가 라인 형태로 구비되는 바, 그 파손 및 유실에 기인하는 셀 갭 유지의 불량이 최대한 억제되며, 따라서, 화면품위의 저하가 방지된다.According to the liquid crystal display device of the present invention as described above, since the strut-type spacer is provided in the form of a line, a defect in cell gap retention due to its breakage and loss is suppressed as much as possible, and therefore, deterioration of the screen quality is prevented.
한편, 지주형 스페이서를 블랙 매트릭스의 전 영역 상에 형성한 컬러필터 기판 구조에 있어서는 후속하는 러빙 공정이나, 액정 주입 공정에 다소 불리할 수 있다.On the other hand, in the color filter substrate structure in which the post spacer is formed on the entire region of the black matrix, it may be somewhat disadvantageous for the subsequent rubbing process or the liquid crystal injection process.
따라서, 본 발명의 다른 실시예로서 지주형 스페이서를 블랙 매트릭스 상에 어느 한 방향으로만 연장되는 라인 형태로 구비시킬 수도 있다.Therefore, as another embodiment of the present invention, the post spacer may be provided in the form of a line extending only in one direction on the black matrix.
자세하게, 도 3a 및 도 3b는 본 발명의 다른 실시예에 따른 지주형 스페이서가 구비된 컬러필터 기판을 도시한 평면도로서, 도시된 바와 같이, 지주형 스페이서(8a, 8b)는 블랙 매트릭스(2) 상에 어느 한 방향으로만, 바람직하게, 러빙 방향 및 액정주입구의 방향을 따라서 라인 형태로 형성된다.3A and 3B are plan views illustrating color filter substrates having post spacers according to another exemplary embodiment of the present invention. As shown, the post spacers 8a and 8b are formed by the black matrix 2. It is formed in the form of a line only in one direction, preferably along the rubbing direction and the direction of the liquid crystal inlet.
여기서, 도 3a는 러빙 방향과 액정주입구의 방향이 기판에 대해 수직 방향인 경우를, 그리고, 도 3b는 러빙 방향과 액정주입구의 방향이 기판에 대해 수평 방향인 경우를 각각 도시한 것이고, 미설명된 도면부호 4는 레드, 그린 및 블루의 삼색으로 구성된 컬러필터를 나타낸다.3A illustrates a case in which the rubbing direction and the direction of the liquid crystal injection hole are perpendicular to the substrate, and FIG. 3B illustrates a case in which the rubbing direction and the direction of the liquid crystal injection hole are horizontal to the substrate, respectively. Reference numeral 4 designates a color filter composed of three colors of red, green and blue.
본 발명의 또 다른 실시예로서, 지주형 스페이서를 블랙 매트릭스의 전 영역 상에 형성하는 경우에, 액정 주입시의 불리함을 해결하면서 액정주입 시간을 단축하고자, 액정주입구를 형성하지 않고, 어레이 기판 또는 컬러필터 기판 중에서 어느 하나의 기판에 액정을 도포한 후, 기판들간을 합착하는 ODF(One Drop Filling) 기술을 사용하여 액정을 주입할 수 있다.As another embodiment of the present invention, in the case where the post spacer is formed on the entire area of the black matrix, in order to shorten the liquid crystal injection time while solving the disadvantages of the liquid crystal injection, the array substrate is not formed and the liquid crystal injection hole is not formed. Alternatively, after the liquid crystal is applied to any one of the color filter substrates, the liquid crystal may be injected using an ODF (One Drop Filling) technique in which the substrates are bonded to each other.
이상에서와 같이, 본 발명은 컬러필터 기판에 지주형 스페이서를 형성하되, 블랙 매트릭스의 전 영역, 또는, 액정층의 러빙방향과 동일한 방향으로 연장되는 라인 형태로 지주형 스페이서를 형성함으로써, 그 유실 및 파손에 의한 셀 갭 유지의 불량을 방지할 수 있으며, 이에 따라, 정확한 셀 갭 유지가 가능하여 액정표시장치의 화면품위를 향상시킬 수 있다.As described above, the present invention forms a strut spacer on the color filter substrate, but forms the strut spacer in the form of a line extending in the entire region of the black matrix or in the same direction as the rubbing direction of the liquid crystal layer. And failure in cell gap maintenance due to breakage can be prevented, whereby accurate cell gap maintenance can be achieved, and the screen quality of the liquid crystal display device can be improved.
기타, 본 발명은 그 요지가 일탈하지 않는 범위에서 다양하게 변경하여 실시할 수 있다.In addition, this invention can be implemented in various changes in the range which does not deviate from the summary.
