The present invention relates to a color filter and a manufacturing method therefor, which can ensure uniform liquid crystal driving and a clear image by preventing the occurrence of a PW step, and can simultaneously implement a micro-pattern and achieve a high contrast ratio through a black matrix layer which is formed in a reverse tapered manner. La présente invention concerne un filtre coloré et un procédé de fabrication associé, qui peut assurer l'activation uniforme des cristaux liquides et une image transparente par la prévention d'une étape de PW, et peut simultanément mettre en oeuvre un micro-motif et produire un rapport de contraste élevé à travers une couche de matrice noire qui est formée de manière conique inversée. 본 발명은 컬러 필터 및 이의 제조 방법에 관한 것으로, PW 단차가 발생하는 것을 방지하여 액정 구동의 균일성과 선명한 영상을 확보할 수 있는 동시에, 역 테이퍼 방식으로 형성된 블랙 매트릭스 층을 통하여 미세 패턴의 구현과 높은 명암비를 달성할 수 있는 것을 특징으로 하는 컬러 필터 및 이의 제조 방법에 관한 것이다.
