Abstract
A tri-state liquid crystal display panel includes a first substrate, a second substrate, a liquid crystal layer, a first electrode, a second electrode, a third electrode and a fourth electrode. The first substrate and the second substrate are disposed oppositely. The liquid crystal layer disposed between the first substrate and the second substrate includes a plurality of polymer network liquid crystals. The first electrode is disposed between the first substrate and the liquid crystal layer, the second electrode is disposed between the second substrate and the liquid crystal layer, and the first and second electrodes include planar electrodes. The third and fourth electrodes are disposed between the first substrate and the liquid crystal layer, and the third and fourth electrodes include patterned electrodes. The tri-state liquid crystal display panel has a transmission state display mode, a dark state display mode and a haze state display mode.
