ABSTRACT:
An IPS (In-Plane-Switching) liquid crystal display panel has column spacers for spacing an active matrix substrate structure from a counter substrate structure, and liquid crystal fills the gap therebetween, wherein the ratio of total contact area between the column spacers and the active matrix substrate structure to the total area occupied by the pixels is fallen within the range from 0.050 percent to 0.150 percent so as to prevent the liquid crystal display panel from irregularity of brightness by keeping the gap constant.
