Abstract
A blue phase liquid crystal composition and a LC display using the composition. The liquid crystal composition includes a first class including a highly polar compound and a second class including a highly conjugated liquid crystal compound. The blue phase liquid crystal display device includes first and second substrates each with polarizer on the exterior surface and the blue phase liquid crystal composition sandwiched therebetween with and patterned electrodes on one of the substrates or both substrates. The patterned electrodes can be T-shaped, chevron or v-shaped, thin comb like shape and can also be flat or trapezoidal. The device outputs different light transmissions from the electrically controllable induced birefringence of the blue phase LC material for a low driving voltage, high transmittance blue phase liquid crystal display device.
