Array substrate used for improving horizontal brightness line and liquid crystal display panel

The invention discloses an array substrate used for improving a horizontal brightness line and a liquid crystal display panel. The array substrate comprises multiple pixels, grid lines and data lines, wherein the pixels are arranged in an array manner; the grid lines are arranged between pixel lines; the data lines are used for providing driving signals for the pixels, wherein the pixels in the same line are connected with the grid lines at the two sides in a crossing manner, so that when the data lines adopt two-point polarity inversion, the horizontal brightness line can be eliminated. According to the array substrate, when the data lines adopt two-point inversion, the horizontal brightness line on the display panel can be eliminated.
