Description
본 발명은 액정표시장치(Liquid Crystal Display 이하, LCD)의 제조방법에 관한 것으로, 특히 LCD판넬 형성전 봉합되지 않는 액정기판의 이면을 표면처리한 다음 LCD판넬을 형성하고 에칭공정을 실시함으로서 기스, 깨짐 등의 손상을 방지하여 소자의 생산성을 향상시키는 기술에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a liquid crystal display (LCD), and in particular, a surface of a liquid crystal substrate that is not sealed before the formation of the LCD panel, followed by the formation of an LCD panel and an etching process. It relates to a technique for improving the productivity of the device by preventing damage such as cracks.
평판표시장치(flat pannel display)의 일종인 LCD는 액체의 유동성과 결정의 광학적 성질이 공존하는 액정에 전계를 가하여 액정의 광학적 이방성을 변화시키는 장치로서, 종래의 음극선관에 비해 소비전력이 낮고 부피가 작다는 이점이 있으며, 대형화 및 고정세화가 가능하여 널리 사용된다.LCD, which is a kind of flat pannel display, is a device that changes the optical anisotropy of liquid crystal by applying electric field to liquid crystal where the liquidity of liquid and the optical property of crystal coexist. It has the advantage of being small, and it is widely used because it can be enlarged and fixed.
일반적으로 상기 LCD의 액정기판장치는 투명전극 패턴 및 화소전극과 스위칭 소자와 연결되어 있는 하측 액정기판과 공통전극이 형성되어 있는 상측 액정기판이 실패턴 및 스페이서(spacer)에 의하여 접촉되고 그 사이의 공간인 셀갭(cell gap)에 액정이 밀봉되어 있는 형태로 구성된다.In general, a liquid crystal substrate of the LCD includes a transparent electrode pattern, a lower liquid crystal substrate connected to a pixel electrode, and a switching element, and an upper liquid crystal substrate on which a common electrode is formed, and a contact between the failed turn points and a spacer. The liquid crystal is sealed in a cell gap which is a space.
상기 상측 및 하측 액정기판 제조의 맨 처음 과정은 석영 혹은 유리와 같은 액정기판의 먼지 및 오염물을 제거하는 것이며, 그 후 투명전극 패턴, 배향막, 칼라필터 및 실패턴등을 형성하고, 상.하측 액정기판을 접합시킨 후, 액정을 주입하고, 앤드실로 밀봉하여 LCD를 완성한다.The first process of manufacturing the upper and lower liquid crystal substrates is to remove dust and contaminants of the liquid crystal substrate such as quartz or glass, and then form a transparent electrode pattern, an alignment layer, a color filter, and a failure turn, and then form upper and lower liquid crystals. After bonding the substrate, the liquid crystal is injected and sealed with an end seal to complete the LCD.
그러나, LCD를 형성하는 동안 액정기판이 많은 공정을 거치면서 기스(scratch), 깨짐(crack) 등에 의해 많은 손상이 가해져 액정기판의 외관불량이 발생하여 소자의 생산성이 저하되는 문제점이 있다.However, as the liquid crystal substrate is subjected to many processes during the formation of the LCD, a lot of damage is applied due to scratches, cracks, etc., resulting in poor appearance of the liquid crystal substrate, thereby lowering the productivity of the device.
이에, 본 발명은 상기한 문제점을 해결하기 위한 것으로 LCD판넬 형성전 액정기판의 이면에 보호막을 형성하고, 소정의 공정으로 LCD판넬을 형성하고 보호막을 제거함으로써 기스, 깨짐 등의 손상을 방지하여 소자의 생산성을 향상시키는 액정표시장치의 제조방법을 제공하는데 그 목적이 있다.Accordingly, the present invention is to solve the above problems by forming a protective film on the back surface of the liquid crystal substrate before forming the LCD panel, forming the LCD panel by a predetermined process and removing the protective film to prevent damage such as gas, cracks, etc. It is an object of the present invention to provide a method for manufacturing a liquid crystal display device which improves productivity.
