The present invention provides a liquid crystal display device and an array substrate of the same. The multiple pixel electrodes located at a same column allow lights having a same color to pass through. Each data line passes around at least one column of the multiple pixel electrodes row by row, and when each data line passes around two adjacent rows of the multiple pixel electrodes, opening directions are opposite. Pixel electrodes located at odd rows are connected with a same data line, pixel electrodes located at even rows are connected with a same data line, and pixel electrodes located at odd rows and even rows are respectively connected with different data lines. The present invention can reduce a bias generated at an edge of the color resist in order to improve a light leakage phenomenon when displaying.
