Disclosed are a liquid crystal display panel and a gate driving circuit thereof. The liquid crystal display panel includes a plurality of pixel units arranged in a matrix, a plurality of scan lines, a gate driving circuit, a plurality of data lines and a data driving circuit. Every two scan lines are corresponded to the pixel units in the same column and alternatively connected to the pixel units in the same column. Each data line is connected to the pixel units in the two rows. The driving abilities of the gate driving signals provided to the two scan lines corresponding to the pixel units in the same column are different. In this manner, the liquid crystal display panel can have less brightness variation and thus have a better display performance.
