1. A liquid crystal display panel, comprising:
a base substrate;
a first electrode layer disposed on one side of the base substrate;
a second electrode layer disposed on one side of the first electrode layer away from the base substrate;
an insulating layer disposed between the first electrode layer and the second electrode layer; and
a source/drain electrode layer disposed on one side of the insulating layer away from the second electrode layer, the source/drain electrode layer comprises wirings;
wherein the liquid crystal display panel comprises an opening area and a non-opening area, in the non-opening area, the wirings overlap with the second electrode layer, the opening area is a light-transmitting display area of the liquid crystal display panel, the non-opening area comprises a non-light-transmitting area between adjacent opening areas and a non-display area, and a thickness of the insulating layer located between the first electrode layer and the second electrode layer in the opening area is less than a thickness of the insulating layer located between the wirings and the second electrode layer in the non-opening area.
