Abstract

본 발명은 표시 장치 및 그 제조 방법에 관한 것으로서, 더욱 상세하게는, 액정 패널, 게이트 PCB, 소스 PCB 및 TAB-IC를 구성하고 있는 표시 장치 및 그 제조 방법에 관한 것이다. 액정 패널 위에 소스 및 게이트 신호 패턴 및 패드를 형성하고 패드에 대응하는 다수의 소스 및 게이트 TAB-IC를 부착하고 액정 패널을 구동하기 위한 신호 PCB 기판을 형성하고 액정 패널과 상기 PCB 기판을 연결한다. 따라서, 본 발명에 따른 액정 표시 장치는 TAB 솔더 패드를 패널 상부에 형성함으로써 리드 간에 쇼트 또는 패드 오픈을 방지하고 PCB를 줄임으로써 액정 패널의 활성 면적을 최대화하고 PCB 기판과 TAB-IC핸들링(handling)에 의한 손상을 줄일 수 있어 원가를 절감할 수 있고, 하나의 공정으로 TAB-IC의 입력단(TAB 솔더)과 출력단(OLB 본딩부)을 동시에 본딩함으로 공정의 단순화 및 공정 시간을 줄일 수 있고, 불량발생 시 재작업에서도 PCB부와 패널부로 구분되어 공정 수율을 높일 수 있는 효과가 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device and a method of manufacturing the same, and more particularly, to a display device constituting a liquid crystal panel, a gate PCB, a source PCB, and a TAB-IC, and a method of manufacturing the same. Source and gate signal patterns and pads are formed on the liquid crystal panel, a plurality of source and gate TAB-ICs corresponding to the pads are attached, a signal PCB substrate for driving the liquid crystal panel is formed, and the liquid crystal panel and the PCB substrate are connected. Accordingly, the liquid crystal display according to the present invention forms a TAB solder pad on the panel to prevent short or pad opening between the leads and reduces the PCB, thereby maximizing the active area of the liquid crystal panel and handling the PCB substrate and TAB-IC handling. It can reduce the damage by the damage and reduce the cost.By simultaneously bonding the input terminal (TAB solder) and output terminal (OLB bonding part) of TAB-IC in one process, the process can be simplified and the process time can be reduced. In case of reworking, it is divided into PCB part and panel part, thereby increasing the process yield.
