Problems solved by technology

[0002] TFT (Thin Film Transistor, Thin Film Transistor) will generate leakage when grayscale voltage is applied, which will cause LCD (Liquid Crystal Display, Liquid Crystal Display) to produce flicker (Flicker) phenomenon and affect the display effect
In order to prevent the grayscale change of the pixel electrode caused by electric leakage and improve or avoid the flicker phenomenon, the LCD needs to have a larger storage capacitor, but a larger storage capacitor requires two larger plates, namely the common electrode of the array substrate and the size of the pixel electrode is larger, which will undoubtedly reduce the aperture ratio of the pixel

Abstract

The invention discloses an array substrate, a liquid crystal display panel, and a liquid crystal display device. A metal layer is arranged between a pixel electrode and a common electrode; and the metal layer and the pixel electrode form a first storage capacitor and the common electrode forms a second storage capacitor, thereby forming a dual-storage capacitor unit. Therefore, the storage capacitance is increased; a scintillation phenomenon caused by TFT electricity leakage is avoided; and a display effect is guaranteed. Moreover, the two storage capacitors are superposed, so that no pixel aperture opening rate is reduced.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to an array substrate, a liquid crystal display panel and a liquid crystal display device. Background technique [0002] TFT (Thin Film Transistor, Thin Film Transistor) will generate leakage current when grayscale voltage is applied, which will cause LCD (Liquid Crystal Display, Liquid Crystal Display) to produce flicker (Flicker) phenomenon, and affect the display effect. In order to prevent the grayscale change of the pixel electrode caused by electric leakage and improve or avoid the flicker phenomenon, the LCD needs to have a larger storage capacitor, but a larger storage capacitor requires two larger plates, that is, the common electrode of the array substrate And the size of the pixel electrode is larger, which will undoubtedly reduce the aperture ratio of the pixel. Contents of the invention [0003] In view of this, the embodiments of the present i...
