The red ink is repeatedly injected on the color filter substrate with a constant distance so that the second sub pixel lines(120) adjacent to the first sub pixel lines are formed. The green ink is repeatedly injected on the color filter substrate with a constant distance so that the third sub pixel lines(130) adjacent to the second sub pixel lines are formed. The black ink is repeatedly injected at every boundary line of the first, second and third sub pixel lines so that the first black matrix lines are formed. The black ink is repeatedly injected with a constant distance vertically to the first, second and third sub pixel lines and the first black matrix lines so that the second black matrix lines are formed.

본 발명은 액정표시장치의 컬러필터 제조방법에 관한 것으로, 특히 잉크젯 프린팅 방식의 컬러필터 패턴 형성방법에 있어서 R(Red), G(Green), B(Blue) 컬러필터 패턴을 형성하기 위한 컬러필터 라인들을 한 번에 한 색상의 컬러필터 라인을 각각 순차적으로 기판에 프린팅하고, 이후 블랙매트릭스 패턴을 프린팅하여 컬러필터 패턴을 형성시킴으로써 잉크젯 프린팅 방식에 의한 컬러필터 패턴 형성 공정을 단순화하고, 비용을 절감시킬 수 있는 액정표시장치용 잉크젯 컬러필터의 패터닝 방법에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color filter manufacturing method of a liquid crystal display device, and more particularly to a color filter for forming an R (Red), G (Green), and B (Blue) color filter pattern in a method of forming a color filter pattern of an inkjet printing method. Lines of color filter lines of one color are printed on the substrate one at a time, and then the black matrix pattern is printed to form a color filter pattern, thereby simplifying the process of forming a color filter pattern by inkjet printing method and reducing costs. It relates to a patterning method of an inkjet color filter for a liquid crystal display device.

컬러필터(Color Filter)는 액정표시장치(Liquid Crystal Display, LCD) 패널에서 색상을 표현하기 위해 사용되는 주요 구성요소로서, 컬러필터의 픽셀단위는 RGB의 3개 서브픽셀로 구성되고, 통상 LCD에서 RGB는 바둑판 구조를 가지고 있다. LCD 컬러필터의 기본적인 패턴을 도 1에 나타내었다. RGB 서브픽셀은 각각의 염료나 색소를 갖는 잉크를 잉크젯 프린터 헤드로부터 각 서브픽셀에 각각 분사하여 형성된다. The color filter is a main component used to express colors in a liquid crystal display (LCD) panel. The pixel unit of the color filter is composed of three subpixels of RGB. RGB has a checkerboard structure. The basic pattern of the LCD color filter is shown in FIG. RGB subpixels are formed by injecting ink having respective dyes or pigments from the inkjet printer head to each subpixel, respectively.

LCD 컬러필터의 RGB 사이에는 블랙매트릭스(Black Matrix, B/M)가 형성되는데, 블랙매트릭스는 빛의 유출과 TFT(Thin Film Transistor)에서의 광전자적 전환을 방지하기 위해 컬러 서브픽셀 사이에 위치해 있다. 블랙매트릭스물질은 투명 기판의 광학적으로 불활성화된 지역에 위치시켜 빛 유출을 방지하고 비결정 실리콘 트랜지스터에 광실드(Light shield)를 제공해준다. 블랙마스크물질은 최적의 명암비를 위해 반사율이 낮아야 하며, 유기물일수도 무기물일수도 있으나 크롬(Cr)이 가장 일반적인 무기물이다.A black matrix (B / M) is formed between the RGB of the LCD color filter, which is located between the color subpixels to prevent light leakage and photoelectric conversion in the thin film transistor (TFT). . The black matrix material is located in an optically inactive area of the transparent substrate to prevent light leakage and provide a light shield for amorphous silicon transistors. The black mask material should have low reflectance for optimal contrast ratio, and may be organic or inorganic, but chromium (Cr) is the most common inorganic material.

도 2a는 종래기술에 따른 잉크젯 컬러필터기판의 평면도이고, 도 2b는 도 2a의 A-A'선 단면도로서, 도시된 바와 같이 종래의 잉크젯 컬러필터의 제조 방법은 투명 기판(미도시함) 위에 크롬 등의 금속막 또는 흑색수지(Black Resin)막을 도포한 후 사진식각방법 등으로 패터닝하여 컬러필터소자가 형성되는 화소영역 이외의 경계로서 격벽(10)을 형성하고, 그 격벽(10) 사이에 잉크를 분사함으로써 수행된다.FIG. 2A is a plan view of an inkjet color filter substrate according to the prior art, and FIG. 2B is a cross-sectional view taken along the line A-A 'of FIG. 2A. As shown, a conventional method of manufacturing an inkjet color filter is shown on a transparent substrate (not shown). A metal film such as chromium or a black resin film is coated and then patterned by a photolithography method to form partition walls 10 as boundaries other than the pixel region in which the color filter elements are formed, and between the partition walls 10. By spraying ink.

즉, 격벽(10) 사이의 투명한 개구부로 정의되는 화소영역에 잉크젯 프린팅 방식으로 적색, 녹색, 및 청색을 띠는 삼색의 잉크(20)를 주입하고 경화하여 RGB의 컬러필터 서브픽셀을 형성한다. 그 결과, 도 1b에 나타낸 것과 같이 투명기판(100) 위에 격벽(10)들 사이에서 RGB의 컬러필터 서브픽셀(20)들이 갇힌 구조를 보이게 된다.That is, three color inks 20 having red, green, and blue colors are injected and cured in the pixel area defined by the transparent openings between the partitions 10 to form RGB color filter subpixels. As a result, as shown in FIG. 1B, the RGB color filter subpixels 20 are trapped between the partitions 10 on the transparent substrate 100.

도 1 내지 도 2b에서 보인 바와 같이, 종래기술에 따른 잉크젯 프린팅 방식에 의한 RGB 서브픽셀의 패턴 형성은 블랙매트릭스에 의해 형성된 격벽(10) 사이의 화소영역에 RGB 서프픽셀을 잉크젯 프린팅 방식으로 주입하여야 하므로, 컬러필터의 순도는 잉크젯 프린터 헤드와 기판에 형성된 패턴의 정교한 정렬과 미세한 분사기술에 의해 크게 좌우되게 된다. As shown in FIG. 1 to FIG. 2B, the pattern formation of the RGB subpixels by the inkjet printing method according to the prior art should inject RGB subpixels into the pixel region between the partitions 10 formed by the black matrix by the inkjet printing method. Therefore, the purity of the color filter is greatly influenced by the fine alignment of the patterns formed on the inkjet printer head and the substrate and the fine jetting technique.

따라서 종래기술에 따른 잉크젯 프린팅 방식에 의한 컬러필터 패턴의 형성과정은 R, G, B 각각의 색상 잉크들을 블랙매트릭스에 의해 기 형성된 패턴에 각각 정확하게 정렬하여 분사해야 하므로 각각의 공정에 소요되는 시간이 과다하였고, 그 공정이 복잡하여 과다 설비투자에 의한 생산원가가 많이 소요되는 문제점이 있었다.Therefore, in the process of forming the color filter pattern by the inkjet printing method according to the prior art, the color inks of R, G, and B must be precisely aligned and sprayed on the patterns formed by the black matrix, respectively, so that the time required for each process is reduced. It was excessive, the process was complicated, there was a problem that a lot of production cost due to the excessive investment of equipment.

따라서 상기한 문제점을 해결하기 위한 본 발명의 목적은 반복적인 포토리소그래피공정을 사용치 아니하고 잉크의 도포와 건조를 반복함으로써 간단한 공정과 적은 비용으로 액정표시장치용 잉크젯 컬러필터의 패터닝 방법을 제공하는데 있다.Accordingly, an object of the present invention for solving the above problems is to provide a method of patterning an inkjet color filter for a liquid crystal display device with a simple process and a low cost by repeating the application and drying of the ink without using a repetitive photolithography process. .

상기와 같은 목적을 달성하기 위하여 본 발명은 R(Red), G(Green), B(Blue) 서브픽셀을 갖는 컬러필터 패턴을 형성하기 위하여 각각의 색상 라인들을 한 번에 한 색상씩 기판의 특정위치에 잉크젯 프린팅하여 삼색의 색상 라인들을 반복적으로 형성한 후, 블랙매트릭스 패턴을 잉크젯 프린팅 방식으로 형성하여 RGB서브픽셀로 이루어지는 컬러필터 패턴을 형성함을 특징으로 하는 액정표시장치용 컬러필터의 잉크젯 패터닝 방법을 제공한다.In order to achieve the above object, the present invention provides a color filter pattern having R (Red), G (Green), and B (Blue) subpixels.
