A liquid crystal display panel and a liquid crystal display are disclosed. The liquid crystal display panel comprises: a first substrate and a second substrate, disposed opposite to each other to form a cell, as well as a liquid crystal layer between the two substrates. On the first substrate, there is formed with a first common electrode and a pixel electrode, arranged at an interval; on the second substrate, there is formed with a set of layers, the set of layers comprising: a second common electrode, and a dielectric layer covering one side of the second common electrode facing the first substrate; and the structure of the set of layers is different at a position directly opposite to the first common electrode from that at a position directly opposite to the pixel electrode.
