(57) [Summary] (with correction) [PROBLEMS] To provide an active matrix type liquid crystal display device which suppresses an afterimage remaining after application of a DC voltage. Kind Code: A1 A dopant having a negative dielectric anisotropy in a liquid crystal layer, a dissociative group only in the minor axis direction of the molecule, and an alkyl group or an alkoxy group at both ends in the molecular axis direction. Was included.
