The invention provides an array substrate including an array of sub-pixels, multiple data lines and multiple scan lines. The array of sub-pixels is divided into multiple column groups along the arrangement direction of the data lines and divided into multiple row groups along the arrangement direction of the scan lines. By the arrangement design of a connection manner of the sub-pixels with the data lines and scan lines in the array substrate, when is driven by a dot inversion method, each column of sub-pixels have intervally arranged well-charged sub-pixels and poorly-charged sub-pixels, so that in a liquid crystal panel including the array substrate, brightnesses of various areas are balanced on the whole and the drawback of the existence of bright and dark lines in the vertical direction is improved. A liquid crystal panel including the array substrate, and a corresponding liquid crystal display device also are provided.
