Abstract

A liquid crystal display panel and liquid crystal display array substrate are disclosed herein. The liquid crystal display array substrate includes scan lines, data lines, first rows of pixel units, and second rows of pixel units. The first rows of pixel units and the second rows of pixel units are arranged alternately. Each of the first rows of pixel units has first pixel structures disposed in a row direction and electrically connected to the scan lines and the data lines, respectively. Each of the second rows of pixel units has second pixel structures disposed along the row direction and electrically connected to the scan lines and the data lines, respectively. The first capacitance value of the first storage capacitor of each first pixel structure is greater than the second capacitance value of the second storage capacitor of each second pixel structure.
