A liquid crystal display panel and a display driving method are disclosed. The liquid crystal display panel includes data lines, scan lines, common electrode lines, pixel units, voltage buffer circuits and common electrode controller units. The pixel units are coupled to corresponding data lines and scan lines. Each pixel unit includes a storage capacitor. The pixel units on the same row are coupled to the same common electrode line. The common electrode controller units drive the common electrode lines to re-charge each pixel unit via the storage capacitor. The voltage buffer circuits are coupled between the common electrode controller units and the common electrode lines. The voltage buffer circuits are used for maintaining the voltage levels on each of the common electrode lines when each of the pixel units is not in their data writing period.
