Abstract

본 발명은 액정표시 소자에 관한 것으로 패턴보임 현상 및 칼라 불균일성을 방지하도록 한 액정표시 소자 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device, and more particularly, to a method for manufacturing a liquid crystal display device to prevent pattern visible phenomenon and color nonuniformity.

종래의 투명도전막 패턴 방법은 유리기판위에 절연막과 투명도전막을 증착하고 포토에치 공정으로 불필요한 부분의 투명도전막을 식각제거하였다.In the conventional transparent conductive film pattern method, an insulating film and a transparent conductive film are deposited on a glass substrate, and an unnecessary portion of the transparent conductive film is etched away by a photoetch process.

따라서, 투명 도전막이 형성된 부분과 투명도전막이 제거된 부위의 귤절율차가 발생하여 패터보임 현상 및 칼라 불균일성이 발생하였다.Therefore, the difference in the regulation ratio between the portion where the transparent conductive film was formed and the portion where the transparent conductive film was removed occurred, resulting in a pattern visible phenomenon and color nonuniformity.

본 발명은 기판위에 칠모막 투명도전막을 형성하고 감광막을 이용하여 패터닝한 뒤 불필요한 투명 도전막을 산화시켜 부도체로 형성한 것이다. 따라서 귤절율차가 발생하지 않아서 패턴 보임현상 및 칼라 불균일성이 방지된다.According to the present invention, a seven-coat transparent conductive film is formed on a substrate and patterned using a photosensitive film, and then an unnecessary transparent conductive film is oxidized to form a non-conductor. Therefore, no regulation ratio is generated, thus preventing pattern visibleness and color unevenness.
