Abstract: A display panel and an array substrate thereof, which include a plurality of sub-pixel groups arranged in a matrix on the array substrate. Each sub-pixel group includes a plurality of sub-pixels arranged along rows and columns. Two adjacent sub-pixels in the same row have different colors, and two adjacent sub-pixels in the same column have the same color. In two adjacent rows of sub-pixels, an odd-numbered column or an even-numbered column is set as a target column. Two sub-pixels of the target column in the sub-pixel group are electrically connected to two adjacent data lines located on both sides of the target column. Two sub-pixels in an adjacent column of the target column are electrically connected to two adjacent data lines located on both sides of the target column. Thus, a risk of crosstalk is effectively reduced.
