Abstract

본 발명은 액정표시장치를 대형으로 하는 경우 종래의 방법을 사용하여 액정 주입을 실시한 경우 액정이 한쪽 방향에서만 주입되기 때문에 액정주입공정중 액정 내에 포함된 작은 기포에 의해 액정 주입구가 막히거나 주입 시간이 길어져서 주입 불량 및 흑점이 발생되며 조립 공정중 봉지 선의 기포 발생으로 인한 보이 누설이 발생한다.In the present invention, when the liquid crystal display device is large in size, when the liquid crystal is injected using the conventional method, the liquid crystal is injected only in one direction, so that the liquid crystal injection hole is blocked by the small bubbles contained in the liquid crystal during the liquid crystal injection process, or the injection time is increased. It becomes longer, causing poor injection and black spots, and void leakage due to air bubbles in the sealing line during the assembly process.

또한 액정을 주입하기 위한 진공도의 유지 시간이 길어지게 되며 액정 주입구를 막기 위해서는 패널 전 면적을 눌러 주기 위한 설비가 필요하다.In addition, the maintenance time of the vacuum degree for injecting the liquid crystal becomes long, and in order to block the liquid crystal inlet, a facility for pressing the entire area of the panel is required.

이러한 문제점을 본 발명에서는 제거하기 위해 액정 주입구를 액정 표시 소자 구동을 위한 패드를 제외한 임의의 부분에 형성시켜 액정 주입 공정과 주입구 봉지 공정이 동싱 이루어지도록 하고 액정 주입 설비와 주입구 봉지 설비가 일체화되도록 하여 액정 주입시 발생하는 기포를 제거하여 봉지선에서의 기포 발생으로 인한 봉지 누설이 발생되는 것을 방지하여 액정 표시 장치를 대형으로 제작할 수 있도록 한 것이다.In order to eliminate this problem in the present invention, the liquid crystal injection hole is formed in any part except the pad for driving the liquid crystal display element so that the liquid crystal injection process and the injection hole encapsulation process are performed simultaneously, and the liquid crystal injection facility and the injection hole encapsulation facility are integrated. Bubbles generated during liquid crystal injection are removed to prevent encapsulation leakage due to bubble generation in the encapsulation line so that the liquid crystal display device can be manufactured in a large size.
