Abstract

본 발명은 LCD의 패턴 이미지 형성 방법에 관한 것으로, 글래스(21)의 상하면에 상하부 금속 마스크(22a, 22b)를 형성하는 단계와, 상하부 금속 마스크(22a, 22b)를 에칭하여 소정 패턴을 형성하는 단계와, 하부 금속 마스크(22b)에 + 전압을 인가하고 ITO 이온을 뿌림으로써 글래스(21)와 금속 마스크의 유도 정전 현상에 의해 ITO 이온이 글래스(21) 위에 증착되는 단계와, 상하부 금속 마스크(22a, 22b)를 제거하는 단계를 구비하는 단계를 구비한다. PEP 공정을 행하지 않음으로써 공정수를 줄이고 원가 절감 및 생상성을 향상시킬 수 있다.The present invention relates to a method for forming a pattern image of an LCD, comprising: forming upper and lower metal masks 22a and 22b on the upper and lower surfaces of the glass 21, and etching the upper and lower metal masks 22a and 22b to form a predetermined pattern. And ITO ions are deposited on the glass 21 by the induced electrostatic phenomenon of the glass 21 and the metal mask by applying a positive voltage to the lower metal mask 22b and sprinkling ITO ions. 22a, 22b). By not performing the PEP process, the number of processes can be reduced, cost reduction, and productivity can be improved.
