Abstract
본 발명은 액정용 칼라 OA 기기 및 TV등에 이용되는 칼라필터에 관한 것으로, 칼라필터 상부에 형성된 보호막을 제거하고 필터층(액티브 부분) 상부에만 투명전극막을 형성한 뒤 비액티브 부분의 글라스 기판 상에 잔류하는 안료 레지듀는 플라즈마 에싱(Ashing) 처리로 제거하므로써 액정공정시 발생되는 실떨어짐, 투명전도막 깨짐, 및 돌기에 의한 상하판 쇼트 등과 같은 필터층의 손상을 억제할 수 있는 고신뢰성의 칼라 필터를 실현할 수 있게 된다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to color filters used for color OA devices and TVs for liquid crystals. The protective film formed on the color filter is removed, and a transparent electrode film is formed only on the filter layer (active part). Pigment resin is removed by plasma ashing to provide a highly reliable color filter that can suppress damage to the filter layer such as dust falling during the liquid crystal process, cracking of the transparent conductive film, and shorting of the upper and lower plates due to projections. It can be realized.
