Liquid crystal display deviceand methods for manufacturing the same

摘要

A liquid crystal display device includes a first substrate having a first alignment base layer disposed thereon, a second substrate facing the first substrate and having a second alignment base layer disposed thereon, and ferroelectric liquid crystals vertically aligned between the first substrate and the second substrate. The first alignment controller combines with the first alignment base layer and includes a side chain longer than that of the first alignment base layer. The second alignment controller combines with the second alignment base layer and includes a side chain longer than that of the second alignment base layer. The ferroelectric liquid crystals are pre-tilted by the first alignment controller and the second alignment controller, and as a result, transmittance may be improved. Because the ferroelectric liquid crystals are pre-tilted, a cell gap may be decreased and high-speed driving may be possible at a low voltage.
