Abstract

An active array substrate, an electrode substrate, and a liquid crystal display panel (LCD) are provided. The LCD includes an active array substrate, an electrode substrate, and a liquid crystal layer. The active array substrate includes a base, a plurality of scan lines and data lines disposed on the base, a plurality of pixel electrodes, and a plurality of active devices. Each of the active devices is electrically connected to the corresponding scan line, date line, and pixel electrode to define a pixel region and a non-display region. The electrode substrate includes a base and a common electrode disposed on the base of the electrode substrate. The liquid crystal layer is formed between the active array substrate and the electrode substrate and includes liquid molecules with a threshold voltage, a saturation voltage and ions located in the non-display region.
