Abstract
To increase the aperture ratio of a transflective liquid crystal display device and suppress a light leakage. Provided is a transflective liquid crystal display device that includes: within a unit pixel, a reflective area including a pixel electrode and a common electrode as a pair and a reflector, and a transmissive area including a pixel electrode and a common electrode as a pair; a liquid crystal layer provided to the reflective area and the transmissive area; storage capacitances for the reflective area and the transmissive area provided in a lower layer of the reflector for changing a potential of the pixel electrode by following a potential of the common electrode; and a suppressing device for suppressing a light leakage in the liquid crystal layer when the pixel electrode is affected by a potential of the reflector due to capacitance coupling generated between the reflector and the pixel electrode.
