摘要：
An active matrix liquid crystal display device is provided, in which an after image remaining after removing an application of a direct current voltage is suppressed. The active matrix liquid crystal display device has a liquid crystal layer containing a liquid crystal molecule having negative dielectric anisotropy and a dopant having a dissociative group.
