1. A liquid crystal display panel, comprising:
a first substrate;
a second substrate;
a liquid crystal layer filled between the first substrate and the second substrate; and
support posts disposed between the first substrate and the second substrate configured to support the first substrate and the second substrate and ensure a distance between the first substrate and the second substrate, wherein each of the support posts comprises a support post body and an expandable auxiliary pad;
wherein in a first state, the auxiliary pad is in a non-expanded state, and in a second state, the auxiliary pad is in an expanded state;
wherein material of the auxiliary pad comprises an expansive material; and
wherein the expansive material comprises cesium-doped lead triiodide perovskite mixed with organic cations.
