Abstract
본 발명은 유리기판의 단차문제와 표면 반사를 제거하기 위하여 유리기판상에 홈을 형성하고 그속에 차광물질을 채워넣어 블랙매트릭스를 형성하는 방법에 관한 것이다.The present invention relates to a method of forming a black matrix by forming a groove on a glass substrate and filling a light blocking material therein in order to eliminate a step problem and surface reflection of the glass substrate.
본 발명의 목적은 상기 종래 기술의 문제점을 해결하기 위하여 단차가 발생하지 않고 표면반사에 의해 표시 품질이 저하되지 않는 블랙매트릭스를 형성하는 것이다.An object of the present invention is to form a black matrix in which a step does not occur and display quality is not degraded by surface reflection in order to solve the problems of the prior art.
이와 같은 본 발명의 목적을 실현하기 위해 본 발명은 유리기판 상에 감광성 포토레지스트를 도포하는 단계,블랙매트릭스 마스크로 상기 포토레지스트를 노광,현상하여 포토레지스트 패턴을 형성하는 단계,상기 유리기판을 습식에 칭하여 홈을 형성하는 단계,유동성 차광물질을 상기 유리기판 전면에 도포하는 단계,상기 차광물질을 상기 홈에만 잔류시킨 채 상기 유리기판의 표면으로부터 제거하는 단계로 이루어진 것을 특징으로 한다.In order to realize the object of the present invention, the present invention comprises the steps of applying a photosensitive photoresist on a glass substrate, forming a photoresist pattern by exposing and developing the photoresist with a black matrix mask, wet the glass substrate Forming a groove, applying a liquid light blocking material to the entire surface of the glass substrate, and removing the light blocking material from the surface of the glass substrate while leaving the light blocking material only in the groove.
상기와 같이 형성된 블랙매트릭스는 차광물질이 유리기판내의 홈으로 충진되기 때문에 단차를 전혀 발생하지 않으며 외부 입사광이 블랙매트릭스에서 반사될 때 반사광의 각도가 크게 바뀌어 반사광이 직접나오지 않는다.따라서 표면 반사에 의한 품질저하를 억제할 수 있다.The black matrix formed as described above does not generate any step because the light blocking material is filled into the grooves in the glass substrate. Quality deterioration can be suppressed.
