Abstract

본 발명은 액정표시소자의 칼라필터 및 그 제조방법에 관한 것으로 종래에는 액정표시소자의 칼라필터를 절연기판상에 제조하기 때문에 R,G,B 칼라필터 사이에서 단차가 발생하여 ITO 전극 증착시 단차가 큰 부분에서 단선이 발생하므로 수율이 저하되고, 단선으로 인해 액정이 칼라필터로 유입되어 액정표시소자의 성능이 저하되는 문제점이 있었다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color filter of a liquid crystal display device and a method of manufacturing the same. In the related art, since a color filter of a liquid crystal display device is manufactured on an insulating substrate, a step is generated between R, G, and B color filters, and thus a step of depositing an ITO electrode. Since a break occurs in a large portion, the yield is lowered, and there is a problem in that the liquid crystal flows into the color filter due to the break and degrades the performance of the liquid crystal display device.

본 발명은 이러한 문제점을 해결하기 위하여 칼라필터를 절연기판 내부의 에칭된 홈부분에 형성하여 단차의 발생을 제거토록 함으로써 수율을 높일 수 있도록 하고, 액정의 침투로 인한 칼라필터의 성능저하를 방지토록 하는 액정표시소자를 제조할 수 있게 된다.In order to solve this problem, the present invention can improve the yield by forming a color filter in the etched groove portion of the insulating substrate to eliminate the occurrence of the step, and to prevent the degradation of the color filter due to the penetration of the liquid crystal The liquid crystal display device can be manufactured.
