Abstract: A liquid crystal display includes a first base substrate, a second base substrate, an electrode part, and a liquid crystal layer. The second base substrate is disposed opposite to the first base substrate. The electrode part is disposed on at least one of the first base substrate and the second base substrate. The liquid crystal layer is disposed between the first base substrate and the second base substrate. The liquid crystal layer includes a liquid crystal composition. The liquid crystal composition includes at least one kind of liquid crystal compounds including a cyclopentadienyl group.
