Abstract
A transflective liquid crystal display panel includes a ferroelectric liquid crystal cell operating in a half V-switching mode. The ferroelectric liquid crystal cell includes a reflective portion and a transmissive portion. A cell gap of the reflective portion is similar to a cell gap of the transmissive portion. A voltage applied to the ferroelectric liquid crystal cell depends on a brightness level of ambient light.
