Liquid crystal display panel and liquid crystal display device

A liquid crystal display panel including a first substrate, a second substrate and liquid crystal interposed between the first and the second substrates, the liquid crystal driven by a fringe electric field,

• wherein the first substrate comprises:
• a gate line and a source line intersecting the gate line, one of the gate line and the source line being a conductive pattern;
• a switching element arranged near an intersection of the gate line and the source line;
• a transparent pixel electrode connected to switching element;
• an insulating layer formed on the transparent pixel electrode and the conductive pattern;
• and
• a transparent common electrode arranged on the insulating layer and facing to the conductive pattern through the insulating layer, the transparent common electrode including a first flat portion above the conductive pattern and extending from a first edge of the conductive pattern to a second edge of the conductive pattern, a step portion near the first edge of the conductive pattern, and a second flat portion extending from the first flat portion through the step portion, and
• wherein the second substrate comprises:
• a shielding layer overlapping the first flat portion, the step portion, and a part of the second flat portion of the transparent common electrode.
