The invention provides a LCD panel, comprising active component array substrate, alignment substrate and liquid crystal layer, where the active component array substrate comprises substrate, multiple scan lines, multiple data lines and multiple pixel cells, where the scan lines and the data lines are arranged on the substrate; the pixel cells are arranged on the substrate and each pixel cell is connected with the corresponding scan and data lines and spans the corresponding scan line; the alignment substrate has multiple alignment bumps, each located above the scan line. Besides, the liquid crystal layer is arranged between the alignment substrate and the active component array substrate. And the invention has better opening ratio and contrast. Besides, the invention reduces the widths of parts of the data lines to make store capacitors able to extend to the data lines so as to further raise the opening ratio of the LCD panel.
