A liquid crystal display is provided, which includes a first substrate, a plurality of pixels, a second substrate, a plurality of floating electrodes, and a liquid crystal layer. The pixels are arranged in an array on the first substrate, and each of the pixels includes a first electrode and a second electrode, wherein a space is maintained between the first electrode and the second electrode. The floating electrodes are disposed on the second substrate and above the spaces. The liquid crystal layer is located between the first substrate and the second substrate, wherein the liquid crystal layer is optically isotropic when the first electrode and the second electrode have no voltage difference; and the liquid crystal layer is optically anisotropic when the first electrode and the second electrode have a voltage difference therebetween.
