Abstract:
1. A method for driving a transflective liquid crystal display (LCD) device including pixels arranged in an array, each of said pixels having a reflective region on which a first pixel electrode connected to a data line via a first switching device wherein a pixel signal is supplied to said data line, a first common electrode and a reflection film are formed, each of said pixel having a transmissive region on which a second pixel electrode connected to said data line via a second switching device, and a second common electrode are formed, and each of said pixels having a common gate line in which said first switching device and said second switching device are respectively connected thereto, said method comprising the steps of: applying a first potential to a liquid crystal layer in said reflective region, and applying a second potential to said liquid crystal layer in said transmissive region, said first potential and said second potential therebetween are opposite magnitudes in each of said pixels, which are due to said first switching device and said second switching device connected to said common gate line being turned ON and a common pixel signal to said first pixel electrode and said second pixel electrode being supplied, and further a first common signal being supplied to said first common electrode, and a second common signal being supplied to said second common electrode, said second common signal being a substantially inverted signal of said first common signal.
