Abstract

본 발명은 액정 표시 소자에 관한 것으로 종래에는 전압 변화폭을 줄이기 위한 소토리지 콘덴서 값을 크게하기 위하여 소토리지 전극 면적을 크게함으로 인해 판넬의 개구율을 감소시켜 소자의 성능을 저하시키는 문제점이 있었다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device. In the related art, in order to increase the value of the storage capacitor to reduce the voltage change range, the area of the storage electrode is increased to reduce the aperture ratio of the panel, thereby reducing the performance of the device.

본 발명의 상기와 같은 종래의 문제점을 감안하여 스토리지 전극위에 게이트 절연막과 반도체 층 및 투명 도전막을 형성하여 전압변화에 따라 가변하는 가변 스토리지 콘덴서를 구성하므로 전압변화의 폭을 최소화하여 판넬의 개구율을 향상하고, 잔상현상과 플리커현상을 방지하여 소자의 성능을 개선하는 효과가 있다.In view of the above-described problems of the present invention, the gate insulating film, the semiconductor layer, and the transparent conductive film are formed on the storage electrode to configure a variable storage capacitor that varies according to the voltage change, thereby minimizing the width of the voltage change to improve the panel opening ratio. In addition, there is an effect of improving the performance of the device by preventing afterimage and flicker.
