위와 같은 구성에 의해, 응답특성, 구동 전압, 시야각에서 장점을 갖는 액정표시장치를 제공할 수 있다.
A liquid crystal display device of the present invention comprises a first substrate and a second substrate facing each other; It disposed on the first substrate and the pixel electrode and a common electrode for forming an electric field in a first direction parallel to the first substrate; The first substrate located in the lower back light unit for supplying light and; Located between the first substrate and the second substrate, the electric field on the first substrate in unapplied state being arranged in a helical structure with a twist along a vertical helix axis, the electric field is applied while maintaining the helical axis in while the first direction and arranged so that in accordance with a liquid crystal layer including a chiral nematic liquid crystal molecules is relaxed the helical structure, the dielectric constant of the chiral nematic liquid crystal molecules is characterized by greater than 20.
By the above-mentioned configuration, it is possible to provide a liquid crystal display apparatus having the advantages in the response characteristic, the driving voltage, the viewing angle.
