Abstract

액정 표시소자의 셀갭을 유지하는 스페이서가 액정 표시소자의 내부 전면에 도포됨에 따라 유효픽셀을 지나는 빛이 스페이서로 인해 광산란됨으로써 액정 표시소자의 컨트라스트 비가 저하되는 것을 방지하기 위하여, 유리기판의 일측면으로 적층되는 투명도전막 및 배향막을 포함하여 형성된 액정 표시소자의 기판부가 그 내측으로 배치되는 밀폐용기와; 이 밀폐용기의 외측으로 설치되어 일정 극성의 전하가 부가된 스페이서가 수용되는 수용용기와; 이 수용용기에 연결되는 동시에 상기 밀폐용기에 관통설치되는 분사부와; 이 분사부에 전기적으로 연결되어 고전압을 발생시키는 변압기과; 상기 수용용기에 이송관으로 연결되어 상기 수용용기에 부가되는 가압가스가 저장된 저장탱크와; 상기 기판부에 전기적으로 연결되어 상기 스페이서가 띠는 극성 전하에 따라 동일극성 또는 반대극성의 전하를 부가하는 발전기가 포함되어 이루어지는 액정 디스플레이의 스페이서 도포시스템을 제공하여, 스페이서로 인한 광산란을 막아 액정 표시소자의 컨트라스비를 증가시킬 수 있게 된다.
